>gnl|CDD|206641 cd00157, Rho, Ras homology family (Rho) of small guanosine
triphosphatases (GTPases). Members of the Rho (Ras
homology) family include RhoA, Cdc42, Rac, Rnd, Wrch1,
RhoBTB, and Rop. There are 22 human Rho family members
identified currently. These proteins are all involved in
the reorganization of the actin cytoskeleton in response
to external stimuli. They also have roles in cell
transformation by Ras in cytokinesis, in focal adhesion
formation and in the stimulation of stress-activated
kinase. These various functions are controlled through
distinct effector proteins and mediated through a
GTP-binding/GTPase cycle involving three classes of
regulating proteins: GAPs (GTPase-activating proteins),
GEFs (guanine nucleotide exchange factors), and GDIs
(guanine nucleotide dissociation inhibitors). Most Rho
proteins contain a lipid modification site at the
C-terminus, with a typical sequence motif CaaX, where a
= an aliphatic amino acid and X = any amino acid. Lipid
binding is essential for membrane attachment, a key
feature of most Rho proteins. Since crystal structures
often lack C-terminal residues, this feature is not
available for annotation in many of the CDs in the
hierarchy.

>gnl|CDD|206704 cd04132, Rho4_like, Ras homology family 4 (Rho4) of small guanosine
triphosphatases (GTPases)-like. Rho4 is a GTPase that
controls septum degradation by regulating secretion of
Eng1 or Agn1 during cytokinesis. Rho4 also plays a role
in cell morphogenesis. Rho4 regulates septation and cell
morphology by controlling the actin cytoskeleton and
cytoplasmic microtubules. The localization of Rho4 is
modulated by Rdi1, which may function as a GDI, and by
Rga9, which is believed to function as a GAP. In S.
pombe, both Rho4 deletion and Rho4 overexpression result
in a defective cell wall, suggesting a role for Rho4 in
maintaining cell wall integrity. Most Rho proteins
contain a lipid modification site at the C-terminus,
with a typical sequence motif CaaX, where a = an
aliphatic amino acid and X = any amino acid. Lipid
binding is essential for membrane attachment, a key
feature of most Rho proteins.

>gnl|CDD|206663 cd01871, Rac1_like, Ras-related C3 botulinum toxin substrate 1 (rho
family, small GTP binding protein Rac1)-like consists of
Rac1, Rac2 and Rac3. The Rac1-like subfamily consists
of Rac1, Rac2, and Rac3 proteins, plus the splice
variant Rac1b that contains a 19-residue insertion near
switch II relative to Rac1. While Rac1 is ubiquitously
expressed, Rac2 and Rac3 are largely restricted to
hematopoietic and neural tissues respectively. Rac1
stimulates the formation of actin lamellipodia and
membrane ruffles. It also plays a role in cell-matrix
adhesion and cell anoikis. In intestinal epithelial
cells, Rac1 is an important regulator of migration and
mediates apoptosis. Rac1 is also essential for
RhoA-regulated actin stress fiber and focal adhesion
complex formation. In leukocytes, Rac1 and Rac2 have
distinct roles in regulating cell morphology, migration,
and invasion, but are not essential for macrophage
migration or chemotaxis. Rac3 has biochemical properties
that are closely related to Rac1, such as effector
interaction, nucleotide binding, and hydrolysis; Rac2
has a slower nucleotide association and is more
efficiently activated by the RacGEF Tiam1. Both Rac1 and
Rac3 have been implicated in the regulation of cell
migration and invasion in human metastatic breast
cancer. Most Rho proteins contain a lipid modification
site at the C-terminus, with a typical sequence motif
CaaX, where a = an aliphatic amino acid and X = any
amino acid. Lipid binding is essential for membrane
attachment, a key feature of most Rho proteins. Due to
the presence of truncated sequences in this CD, the
lipid modification site is not available for annotation.

>gnl|CDD|206662 cd01870, RhoA_like, Ras homology family A (RhoA)-like includes
RhoA, RhoB and RhoC. The RhoA subfamily consists of
RhoA, RhoB, and RhoC. RhoA promotes the formation of
stress fibers and focal adhesions, regulating cell
shape, attachment, and motility. RhoA can bind to
multiple effector proteins, thereby triggering different
downstream responses. In many cell types, RhoA mediates
local assembly of the contractile ring, which is
necessary for cytokinesis. RhoA is vital for muscle
contraction; in vascular smooth muscle cells, RhoA plays
a key role in cell contraction, differentiation,
migration, and proliferation. RhoA activities appear to
be elaborately regulated in a time- and space-dependent
manner to control cytoskeletal changes. Most Rho
proteins contain a lipid modification site at the
C-terminus, with a typical sequence motif CaaX, where a
= an aliphatic amino acid and X = any amino acid. Lipid
binding is essential for membrane attachment, a key
feature of most Rho proteins. RhoA and RhoC are observed
only in geranylgeranylated forms; however, RhoB can be
present in palmitoylated, farnesylated, and
geranylgeranylated forms. RhoA and RhoC are highly
relevant for tumor progression and invasiveness;
however, RhoB has recently been suggested to be a tumor
suppressor. Due to the presence of truncated sequences
in this CD, the lipid modification site is not available
for annotation.

>gnl|CDD|133277 cd01875, RhoG, Ras homolog family, member G (RhoG) of small
guanosine triphosphatases (GTPases). RhoG is a GTPase
with high sequence similarity to members of the Rac
subfamily, including the regions involved in effector
recognition and binding. However, RhoG does not bind to
known Rac1 and Cdc42 effectors, including proteins
containing a Cdc42/Rac interacting binding (CRIB) motif.
Instead, RhoG interacts directly with Elmo, an upstream
regulator of Rac1, in a GTP-dependent manner and forms a
ternary complex with Dock180 to induce activation of
Rac1. The RhoG-Elmo-Dock180 pathway is required for
activation of Rac1 and cell spreading mediated by
integrin, as well as for neurite outgrowth induced by
nerve growth factor. Thus RhoG activates Rac1 through
Elmo and Dock180 to control cell morphology. RhoG has
also been shown to play a role in caveolar trafficking
and has a novel role in signaling the neutrophil
respiratory burst stimulated by G protein-coupled
receptor (GPCR) agonists. Most Rho proteins contain a
lipid modification site at the C-terminus, with a
typical sequence motif CaaX, where a = an aliphatic
amino acid and X = any amino acid. Lipid binding is
essential for membrane attachment, a key feature of most
Rho proteins.

>gnl|CDD|206664 cd01874, Cdc42, cell division cycle 42 (Cdc42) is a small GTPase of
the Rho family. Cdc42 is an essential GTPase that
belongs to the Rho family of Ras-like GTPases. These
proteins act as molecular switches by responding to
exogenous and/or endogenous signals and relaying those
signals to activate downstream components of a
biological pathway. Cdc42 transduces signals to the
actin cytoskeleton to initiate and maintain polarized
growth and to mitogen-activated protein morphogenesis.
In the budding yeast Saccharomyces cerevisiae, Cdc42
plays an important role in multiple actin-dependent
morphogenetic events such as bud emergence,
mating-projection formation, and pseudohyphal growth. In
mammalian cells, Cdc42 regulates a variety of
actin-dependent events and induces the JNK/SAPK protein
kinase cascade, which leads to the activation of
transcription factors within the nucleus. Cdc42 mediates
these processes through interactions with a myriad of
downstream effectors, whose number and regulation we are
just starting to understand. In addition, Cdc42 has been
implicated in a number of human diseases through
interactions with its regulators and downstream
effectors. Most Rho proteins contain a lipid
modification site at the C-terminus, with a typical
sequence motif CaaX, where a = an aliphatic amino acid
and X = any amino acid. Lipid binding is essential for
membrane attachment, a key feature of most Rho proteins.
Due to the presence of truncated sequences in this CD,
the lipid modification site is not available for

>gnl|CDD|206705 cd04133, Rop_like, Rho-related protein from plants (Rop)-like. The
Rop (Rho-related protein from plants) subfamily plays a
role in diverse cellular processes, including
cytoskeletal organization, pollen and vegetative cell
growth, hormone responses, stress responses, and
pathogen resistance. Rops are able to regulate several
downstream pathways to amplify a specific signal by
acting as master switches early in the signaling
cascade. They transmit a variety of extracellular and
intracellular signals. Rops are involved in establishing
cell polarity in root-hair development, root-hair
elongation, pollen-tube growth, cell-shape formation,
responses to hormones such as abscisic acid (ABA) and
auxin, responses to abiotic stresses such as oxygen
deprivation, and disease resistance and disease
susceptibility. An individual Rop can have a unique
function or an overlapping function shared with other
Rop proteins; in addition, a given Rop-regulated
function can be controlled by one or multiple Rop
proteins. For example, Rop1, Rop3, and Rop5 are all
involved in pollen-tube growth; Rop2 plays a role in
response to low-oxygen environments, cell-morphology,
and root-hair development; root-hair development is also
regulated by Rop4 and Rop6; Rop6 is also responsible for
ABA response, and ABA response is also regulated by
Rop10. Plants retain some of the regulatory mechanisms
that are shared by other members of the Rho family, but
have also developed a number of unique modes for
regulating Rops. Unique RhoGEFs have been identified
that are exclusively active toward Rop proteins, such as
those containing the domain PRONE (plant-specific Rop
nucleotide exchanger). Most Rho proteins contain a lipid
modification site at the C-terminus, with a typical
sequence motif CaaX, where a = an aliphatic amino acid
and X = any amino acid. Lipid binding is essential for
membrane attachment, a key feature of most Rho proteins.

>gnl|CDD|133330 cd04130, Wrch_1, Wnt-1 responsive Cdc42 homolog (Wrch-1) is a Rho
family GTPase similar to Cdc42. Wrch-1 (Wnt-1
responsive Cdc42 homolog) is a Rho family GTPase that
shares significant sequence and functional similarity
with Cdc42. Wrch-1 was first identified in mouse mammary
epithelial cells, where its transcription is upregulated
in Wnt-1 transformation. Wrch-1 contains N- and
C-terminal extensions relative to cdc42, suggesting
potential differences in cellular localization and
function. The Wrch-1 N-terminal extension contains
putative SH3 domain-binding motifs and has been shown to
bind the SH3 domain-containing protein Grb2, which
increases the level of active Wrch-1 in cells. Unlike
Cdc42, which localizes to the cytosol and perinuclear
membranes, Wrch-1 localizes extensively with the plasma
membrane and endosomes. The membrane association,
localization, and biological activity of Wrch-1 indicate
an atypical model of regulation distinct from other Rho
family GTPases. Most Rho proteins contain a lipid
modification site at the C-terminus, with a typical
sequence motif CaaX, where a = an aliphatic amino acid

integrity, control of growth polarity, and maintenance
of growth direction. Rho2 activates the protein kinase C

typical sequence motif CaaX, where a = an aliphatic
amino acid and X = any amino acid. Lipid binding is
essential for proper intracellular localization via

the GDP/GTP cycling is regulated by GEFs (guanine
nucleotide exchange factors), GAPs (GTPase-activating

suggesting an important role in promoting axonal
outgrowth and regeneration. TC10 regulates translocation
of insulin-stimulated GLUT4 in adipocytes and has also
been shown to bind directly to Golgi COPI coat proteins.
GTP-bound TC10 in vitro can bind numerous potential
effectors. Depending on its subcellular localization and
distinct functional domains, TC10 can differentially
regulate two types of filamentous actin in adipocytes.
TC10 mRNAs are highly expressed in three types of mouse
muscle tissues: leg skeletal muscle, cardiac muscle, and
uterus; they were also present in brain, with higher
levels in adults than in newborns. TC10 has also been
shown to play a role in regulating the expression of
cystic fibrosis transmembrane conductance regulator
(CFTR) through interactions with CFTR-associated ligand
(CAL). The GTP-bound form of TC10 directs the
trafficking of CFTR from the juxtanuclear region to the
secretory pathway toward the plasma membrane, away from
CAL-mediated DFTR degradation in the lysosome. Most Rho
proteins contain a lipid modification site at the
C-terminus, with a typical sequence motif CaaX, where a
= an aliphatic amino acid and X = any amino acid. Lipid
binding is essential for membrane attachment, a key
feature of most Rho proteins. Due to the presence of
truncated sequences in this CD, the lipid modification
site is not available for annotation.

triphosphatases (GTPases). Rho3 is a member of the Rho
family found only in fungi. Rho3 is believed to regulate
cell polarity by interacting with the diaphanous/formin
family protein For3 to control both the actin
cytoskeleton and microtubules. Rho3 is also believed to
have a direct role in exocytosis that is independent of
its role in regulating actin polarity. The function in
exocytosis may be two-pronged: first, in the transport
of post-Golgi vesicles from the mother cell to the bud,
mediated by myosin (Myo2); second, in the docking and
fusion of vesicles to the plasma membrane, mediated by
an exocyst (Exo70) protein. Most Rho proteins contain a

>gnl|CDD|206640 cd00154, Rab, Ras-related in brain (Rab) family of small guanosine
triphosphatases (GTPases). Rab GTPases form the largest
family within the Ras superfamily. There are at least 60
Rab genes in the human genome, and a number of Rab
GTPases are conserved from yeast to humans. Rab GTPases
are small, monomeric proteins that function as molecular
switches to regulate vesicle trafficking pathways. The
different Rab GTPases are localized to the cytosolic
face of specific intracellular membranes, where they
regulate distinct steps in membrane traffic pathways. In
the GTP-bound form, Rab GTPases recruit specific sets of
effector proteins onto membranes. Through their
effectors, Rab GTPases regulate vesicle formation,
actin- and tubulin-dependent vesicle movement, and
membrane fusion. GTPase activating proteins (GAPs)
interact with GTP-bound Rab and accelerate the
hydrolysis of GTP to GDP. Guanine nucleotide exchange
factors (GEFs) interact with GDP-bound Rabs to promote
the formation of the GTP-bound state. Rabs are further
regulated by guanine nucleotide dissociation inhibitors
(GDIs), which mask C-terminal lipid binding and promote
cytosolic localization. While most unicellular organisms
possess 5-20 Rab members, several have been found to
possess 60 or more Rabs; for many of these Rab isoforms,
homologous proteins are not found in other organisms.
Most Rab GTPases contain a lipid modification site at
the C-terminus, with sequence motifs CC, CXC, or CCX.
Lipid binding is essential for membrane attachment, a
key feature of most Rab proteins. Since crystal
structures often lack C-terminal residues, the lipid
modification site is not available for annotation in
many of the CDs in the hierarchy, but is included where
possible.

subfamily. Rnd3/RhoE/Rho8 is a member of the novel Rho
subfamily Rnd, together with Rnd1/Rho6 and Rnd2/Rho7.
Rnd3/RhoE is known to bind the serine-threonine kinase
ROCK I. Unphosphorylated Rnd3/RhoE associates primarily
with membranes, but ROCK I-phosphorylated Rnd3/RhoE
localizes in the cytosol. Phosphorylation of Rnd3/RhoE
correlates with its activity in disrupting RhoA-induced
stress fibers and inhibiting Ras-induced fibroblast
transformation. In cells that lack stress fibers, such
as macrophages and monocytes, Rnd3/RhoE induces a
redistribution of actin, causing morphological changes
in the cell. In addition, Rnd3/RhoE has been shown to
inhibit cell cycle progression in G1 phase at a point
upstream of the pRb family pocket protein checkpoint.
Rnd3/RhoE has also been shown to inhibit Ras- and
Raf-induced fibroblast transformation. In mammary
epithelial tumor cells, Rnd3/RhoE regulates the assembly
of the apical junction complex and tight junction
formation. Rnd3/RhoE is underexpressed in prostate
cancer cells both in vitro and in vivo; re-expression of
Rnd3/RhoE suppresses cell cycle progression and
increases apoptosis, suggesting it may play a role in
tumor suppression. Most Rho proteins contain a lipid

and X = any amino acid. Lipid binding is essential for
membrane attachment, a key feature of most Rho proteins.

as well as R-Ras, Rap, Ral, Rheb, Rhes, ARHI, RERG,
Rin/Rit, RSR1, RRP22, Ras2, Ras-dva, and RGK proteins.
Ras proteins regulate cell growth, proliferation and
differentiation. Ras is activated by guanine nucleotide
exchange factors (GEFs) that release GDP and allow GTP
binding. Many RasGEFs have been identified. These are
sequestered in the cytosol until activation by growth
factors triggers recruitment to the plasma membrane or
Golgi, where the GEF colocalizes with Ras. Active
GTP-bound Ras interacts with several effector proteins:
among the best characterized are the Raf kinases,
phosphatidylinositol 3-kinase (PI3K), RalGEFs and
NORE/MST1. Most Ras proteins contain a lipid
modification site at the C-terminus, with a typical

the novel Rho subfamily Rnd, together with Rnd1/Rho6 and
Rnd3/RhoE/Rho8. Rnd2/Rho7 is transiently expressed in
radially migrating cells in the brain while they are
within the subventricular zone of the hippocampus and
cerebral cortex. These migrating cells typically develop
into pyramidal neurons. Cells that exogenously expressed
Rnd2/Rho7 failed to migrate to upper layers of the
brain, suggesting that Rnd2/Rho7 plays a role in the
radial migration and morphological changes of developing
pyramidal neurons, and that Rnd2/Rho7 degradation is
necessary for proper cellular migration. The Rnd2/Rho7
GEF Rapostlin is found primarily in the brain and
together with Rnd2/Rho7 induces dendrite branching.
Unlike Rnd1/Rho6 and Rnd3/RhoE/Rho8, which are RhoA
antagonists, Rnd2/Rho7 binds the GEF Pragmin and
significantly stimulates RhoA activity and Rho-A
mediated cell contraction. Rnd2/Rho7 is also found to be
expressed in spermatocytes and early spermatids, with
male-germ-cell Rac GTPase-activating protein
(MgcRacGAP), where it localizes to the Golgi-derived

>gnl|CDD|133275 cd01873, RhoBTB, RhoBTB protein is an atypical member of the Rho
family of small GTPases. Members of the RhoBTB
subfamily of Rho GTPases are present in vertebrates,
Drosophila, and Dictyostelium. RhoBTB proteins are
characterized by a modular organization, consisting of a
GTPase domain, a proline rich region, a tandem of two
BTB (Broad-Complex, Tramtrack, and Bric a brac) domains,
and a C-terminal region of unknown function. RhoBTB
proteins may act as docking points for multiple
components participating in signal transduction
cascades. RhoBTB genes appeared upregulated in some
cancer cell lines, suggesting a participation of RhoBTB
proteins in the pathogenesis of particular tumors. Note
that the Dictyostelium RacA GTPase domain is more
closely related to Rac proteins than to RhoBTB proteins,
where RacA actually belongs. Thus, the Dictyostelium
RacA is not included here. Most Rho proteins contain a
lipid modification site at the C-terminus; however,
RhoBTB is one of few Rho subfamilies that lack this
feature.

and K-Ras4A/4B. H-Ras/N-Ras/K-Ras subfamily. H-Ras,
N-Ras, and K-Ras4A/4B are the prototypical members of
the Ras family. These isoforms generate distinct signal
outputs despite interacting with a common set of
activators and effectors, and are strongly associated
with oncogenic progression in tumor initiation. Mutated
versions of Ras that are insensitive to GAP stimulation
(and are therefore constitutively active) are found in a
significant fraction of human cancers. Many Ras guanine
nucleotide exchange factors (GEFs) have been identified.
They are sequestered in the cytosol until activation by
growth factors triggers recruitment to the plasma
membrane or Golgi, where the GEF colocalizes with Ras.
Active (GTP-bound) Ras interacts with several effector
proteins that stimulate a variety of diverse cytoplasmic
signaling activities. Some are known to positively
mediate the oncogenic properties of Ras, including Raf,
phosphatidylinositol 3-kinase (PI3K), RalGEFs, and
Tiam1. Others are proposed to play negative regulatory
roles in oncogenesis, including RASSF and NORE/MST1.
Most Ras proteins contain a lipid modification site at
the C-terminus, with a typical sequence motif CaaX,
where a = an aliphatic amino acid and X = any amino
acid. Lipid binding is essential for membrane
attachment, a key feature of most Ras proteins. Due to
the presence of truncated sequences in this CD, the
lipid modification site is not available for annotation.

M-Ras/R-Ras3, and related members of the Ras family.
M-Ras is expressed in lympho-hematopoetic cells. It
interacts with some of the known Ras effectors, but
appears to also have its own effectors. Expression of
mutated M-Ras leads to transformation of several types
of cell lines, including hematopoietic cells, mammary
epithelial cells, and fibroblasts. Overexpression of
M-Ras is observed in carcinomas from breast, uterus,
thyroid, stomach, colon, kidney, lung, and rectum. In
addition, expression of a constitutively active M-Ras
mutant in murine bone marrow induces a malignant mast
cell leukemia that is distinct from the monocytic
leukemia induced by H-Ras. TC21, along with H-Ras, has
been shown to regulate the branching morphogenesis of
ureteric bud cell branching in mice. Most Ras proteins

homologous RalA and RalB. The Ral (Ras-like) subfamily
consists of the highly homologous RalA and RalB. Ral
proteins are believed to play a crucial role in
tumorigenesis, metastasis, endocytosis, and actin
cytoskeleton dynamics. Despite their high sequence
similarity (>80% sequence identity), nonoverlapping and
opposing functions have been assigned to RalA and RalBs
in tumor migration. In human bladder and prostate cancer
cells, RalB promotes migration while RalA inhibits it. A
Ral-specific set of GEFs has been identified that are
activated by Ras binding. This RalGEF activity is
enhanced by Ras binding to another of its target
proteins, phosphatidylinositol 3-kinase (PI3K). Ral
effectors include RLIP76/RalBP1, a Rac/cdc42 GAP, and
the exocyst (Sec6/8) complex, a heterooctomeric protein
complex that is involved in tethering vesicles to
specific sites on the plasma membrane prior to
exocytosis. In rat kidney cells, RalB is required for
functional assembly of the exocyst and for localizing
the exocyst to the leading edge of migrating cells. In
human cancer cells, RalA is required to support
anchorage-independent proliferation and RalB is required
to suppress apoptosis. RalA has been shown to localize
to the plasma membrane while RalB is localized to the
intracellular vesicles. Most Ras proteins contain a

>gnl|CDD|206709 cd04137, RheB, Ras Homolog Enriched in Brain (RheB) is a small
GTPase. Rheb (Ras Homolog Enriched in Brain) subfamily.
Rheb was initially identified in rat brain, where its
expression is elevated by seizures or by long-term
potentiation. It is expressed ubiquitously, with
elevated levels in muscle and brain. Rheb functions as
an important mediator between the tuberous sclerosis
complex proteins, TSC1 and TSC2, and the mammalian
target of rapamycin (TOR) kinase to stimulate cell
growth. TOR kinase regulates cell growth by controlling
nutrient availability, growth factors, and the energy
status of the cell. TSC1 and TSC2 form a dimeric complex
that has tumor suppressor activity, and TSC2 is a GTPase
activating protein (GAP) for Rheb. The TSC1/TSC2 complex
inhibits the activation of TOR kinase through Rheb. Rheb
has also been shown to induce the formation of large
cytoplasmic vacuoles in a process that is dependent on
the GTPase cycle of Rheb, but independent of the TOR
kinase, suggesting Rheb plays a role in endocytic
trafficking that leads to cell growth and cell-cycle
progression. Most Ras proteins contain a lipid
modification site at the C-terminus, with a typical
sequence motif CaaX, where a = an aliphatic amino acid
and X = any amino acid. Lipid binding is essential for
membrane attachment, a key feature of most Ras proteins.

a small Rab GTPase that regulates vesicular traffic from
early to late endosomal stages of the endocytic pathway.
The yeast Ypt7 and mammalian Rab7 are both involved in
transport to the vacuole/lysosome, whereas Ypt7 is also
required for homotypic vacuole fusion. Mammalian Rab7 is
an essential participant in the autophagic pathway for
sequestration and targeting of cytoplasmic components to

>gnl|CDD|206708 cd04136, Rap_like, Rap-like family consists of Rap1, Rap2 and RSR1.
The Rap subfamily consists of the Rap1, Rap2, and RSR1.
Rap subfamily proteins perform different cellular
functions, depending on the isoform and its subcellular
localization. For example, in rat salivary gland,
neutrophils, and platelets, Rap1 localizes to secretory
granules and is believed to regulate exocytosis or the
formation of secretory granules. Rap1 has also been
shown to localize in the Golgi of rat fibroblasts,
zymogen granules, plasma membrane, and microsomal
membrane of the pancreatic acini, as well as in the
endocytic compartment of skeletal muscle cells and
fibroblasts. Rap1 localizes in the nucleus of human
oropharyngeal squamous cell carcinomas (SCCs) and cell
lines. Rap1 plays a role in phagocytosis by controlling
the binding of adhesion receptors (typically integrins)
to their ligands. In yeast, Rap1 has been implicated in
multiple functions, including activation and silencing
of transcription and maintenance of telomeres. Rap2 is
involved in multiple functions, including activation of
c-Jun N-terminal kinase (JNK) to regulate the actin
cytoskeleton and activation of the Wnt/beta-catenin
signaling pathway in embryonic Xenopus. A number of
effector proteins for Rap2 have been identified,
including isoform 3 of the human mitogen-activated
protein kinase kinase kinase kinase 4 (MAP4K4) and
Traf2- and Nck-interacting kinase (TNIK), and the
RalGEFs RalGDS, RGL, and Rlf, which also interact with
Rap1 and Ras. RSR1 is the fungal homolog of Rap1 and
Rap2. In budding yeasts, it is involved in selecting a
site for bud growth, which directs the establishment of
cell polarization. The Rho family GTPase Cdc42 and its
GEF, Cdc24, then establish an axis of polarized growth.
It is believed that Cdc42 interacts directly with RSR1
in vivo. In filamentous fungi such as Ashbya gossypii,
RSR1 is a key regulator of polar growth in the hypha.
Most Ras proteins contain a lipid modification site at

in eukaryotes: the Ras, Rho, Rab, and Sar1/Arf families.
This superfamily also includes proteins like the GTP
translation factors, Era-like GTPases, and G-alpha chain
of the heterotrimeric G proteins. Members of the Ras
superfamily regulate a wide variety of cellular
functions: the Ras family regulates gene expression, the
Rho family regulates cytoskeletal reorganization and
gene expression, the Rab and Sar1/Arf families regulate
vesicle trafficking, and the Ran family regulates
nucleocytoplasmic transport and microtubule
organization. The GTP translation factor family
regulates initiation, elongation, termination, and
release in translation, and the Era-like GTPase family
regulates cell division, sporulation, and DNA
replication. Members of the Ras superfamily are
identified by the GTP binding site, which is made up of
five characteristic sequence motifs, and the switch I
and switch II regions.

the Rap subfamily of the Ras family that is found in
fungi. In budding yeasts, RSR1 is involved in selecting
a site for bud growth on the cell cortex, which directs
the establishment of cell polarization. The Rho family
GTPase cdc42 and its GEF, cdc24, then establish an axis
of polarized growth by organizing the actin cytoskeleton
and secretory apparatus at the bud site. It is believed
that cdc42 interacts directly with RSR1 in vivo. In
filamentous fungi, polar growth occurs at the tips of
hypha and at novel growth sites along the extending
hypha. In Ashbya gossypii, RSR1 is a key regulator of
hyphal growth, localizing at the tip region and
regulating in apical polarization of the actin
cytoskeleton. Most Ras proteins contain a lipid
modification site at the C-terminus, with a typical
sequence motif CaaX, where a = an aliphatic amino acid
and X = any amino acid. Lipid binding is essential for
membrane attachment, a key feature of most Ras proteins.

>gnl|CDD|133375 cd04175, Rap1, Rap1 family GTPase consists of Rap1a and Rap1b
isoforms. The Rap1 subgroup is part of the Rap
subfamily of the Ras family. It can be further divided
into the Rap1a and Rap1b isoforms. In humans, Rap1a and
Rap1b share 95% sequence homology, but are products of
two different genes located on chromosomes 1 and 12,
respectively. Rap1a is sometimes called smg p21 or Krev1
in the older literature. Rap1 proteins are believed to
perform different cellular functions, depending on the
isoform, its subcellular localization, and the effector
proteins it binds. For example, in rat salivary gland,
neutrophils, and platelets, Rap1 localizes to secretory
granules and is believed to regulate exocytosis or the
formation of secretory granules. Rap1 has also been
shown to localize in the Golgi of rat fibroblasts,
zymogen granules, plasma membrane, and the microsomal
membrane of pancreatic acini, as well as in the
endocytic compartment of skeletal muscle cells and
fibroblasts. High expression of Rap1 has been observed
in the nucleus of human oropharyngeal squamous cell
carcinomas (SCCs) and cell lines; interestingly, in the
SCCs, the active GTP-bound form localized to the
nucleus, while the inactive GDP-bound form localized to
the cytoplasm. Rap1 plays a role in phagocytosis by
controlling the binding of adhesion receptors (typically
integrins) to their ligands. In yeast, Rap1 has been
implicated in multiple functions, including activation
and silencing of transcription and maintenance of
telomeres. Rap1a, which is stimulated by T-cell receptor
(TCR) activation, is a positive regulator of T cells by
directing integrin activation and augmenting lymphocyte
responses. In murine hippocampal neurons, Rap1b
determines which neurite will become the axon and
directs the recruitment of Cdc42, which is required for
formation of dendrites and axons. In murine platelets,
Rap1b is required for normal homeostasis in vivo and is
involved in integrin activation. Most Ras proteins
contain a lipid modification site at the C-terminus,
with a typical sequence motif CaaX, where a = an
aliphatic amino acid and X = any amino acid. Lipid
binding is essential for membrane attachment, a key

(Rab8, Rab10, Rab13). Rab8/Sec4/Ypt2 are known or
suspected to be involved in post-Golgi transport to the
plasma membrane. It is likely that these Rabs have
functions that are specific to the mammalian lineage and
have no orthologs in plants. Rab8 modulates polarized
membrane transport through reorganization of actin and
microtubules, induces the formation of new surface
extensions, and has an important role in directed
membrane transport to cell surfaces. The Ypt2 gene of
the fission yeast Schizosaccharomyces pombe encodes a
member of the Ypt/Rab family of small GTP-binding

cerevisiae but closer to mammalian Rab8. GTPase
activating proteins (GAPs) interact with GTP-bound Rab
and accelerate the hydrolysis of GTP to GDP. Guanine

>gnl|CDD|206643 cd00877, Ran, Ras-related nuclear proteins (Ran)/TC4 family of
small GTPases. Ran GTPase is involved in diverse
biological functions, such as nuclear transport, spindle
formation during mitosis, DNA replication, and cell
division. Among the Ras superfamily, Ran is a unique
small G protein. It does not have a lipid modification
motif at the C-terminus to bind to the membrane, which
is often observed within the Ras superfamily. Ran may
therefore interact with a wide range of proteins in
various intracellular locations. Like other GTPases, Ran
exists in GTP- and GDP-bound conformations that interact
differently with effectors. Conversion between these
forms and the assembly or disassembly of effector
complexes requires the interaction of regulator
proteins. The intrinsic GTPase activity of Ran is very
low, but it is greatly stimulated by a GTPase-activating
protein (RanGAP1) located in the cytoplasm. By contrast,
RCC1, a guanine nucleotide exchange factor that
generates RanGTP, is bound to chromatin and confined to
the nucleus. Ran itself is mobile and is actively
imported into the nucleus by a mechanism involving
NTF-2. Together with the compartmentalization of its
regulators, this is thought to produce a relatively high
concentration of RanGTP in the nucleus.

(Ras-like protein in all tissues), Rin (Ras-like protein
in neurons) and Ric (Ras-related protein which interacts
with calmodulin) form a subfamily with several unique
structural and functional characteristics. These
proteins all lack a the C-terminal CaaX lipid-binding
motif typical of Ras family proteins, and Rin and Ric
contain calmodulin-binding domains. Rin, which is
expressed only in neurons, induces neurite outgrowth in
rat pheochromocytoma cells through its association with
calmodulin and its activation of endogenous Rac/cdc42.
Rit, which is ubiquitously expressed in mammals,
inhibits growth-factor withdrawl-mediated apoptosis and
induces neurite extension in pheochromocytoma cells. Rit
and Rin are both able to form a ternary complex with
PAR6, a cell polarity-regulating protein, and Rac/cdc42.
This ternary complex is proposed to have physiological
function in processes such as tumorigenesis. Activated
Ric is likely to signal in parallel with the Ras pathway
or stimulate the Ras pathway at some upstream point, and
binding of calmodulin to Ric may negatively regulate Ric
activity.

syndrome (Griscelli syndrome or GS), Hermansky-Pudlak
syndrome, and choroidermia. In the case of GS, a rare,
autosomal recessive disease, a Rab27a mutation is
directly responsible for the disorder. When Rab27a is

Rab33B. Rab33B/Rab33A subfamily. Rab33B is ubiquitously
expressed in mouse tissues and cells, where it is
localized to the medial Golgi cisternae. It colocalizes
with alpha-mannose II. Together with the other cisternal
Rabs, Rab6A and Rab6A', it is believed to regulate the
Golgi response to stress and is likely a molecular
target in stress-activated signaling pathways. Rab33A
(previously known as S10) is expressed primarily in the
brain and immune system cells. In humans, it is located
on the X chromosome at Xq26 and its expression is
down-regulated in tuberculosis patients. Experimental
evidence suggests that Rab33A is a novel CD8+ T cell
factor that likely plays a role in tuberculosis disease
processes. GTPase activating proteins (GAPs) interact
with GTP-bound Rab and accelerate the hydrolysis of GTP
to GDP. Guanine nucleotide exchange factors (GEFs)
interact with GDP-bound Rabs to promote the formation of
the GTP-bound state. Rabs are further regulated by
guanine nucleotide dissociation inhibitors (GDIs), which
facilitate Rab recycling by masking C-terminal lipid
binding and promoting cytosolic localization. Most Rab
GTPases contain a lipid modification site at the
C-terminus, with sequence motifs CC, CXC, or CCX. Lipid
binding is essential for membrane attachment, a key
feature of most Rab proteins. Due to the presence of
truncated sequences in this CD, the lipid modification
site is not available for annotation.

subfamily. Rab23 is a member of the Rab family of small
GTPases. In mouse, Rab23 has been shown to function as a
negative regulator in the sonic hedgehog (Shh) signaling
pathway. Rab23 mediates the activity of Gli2 and Gli3,
transcription factors that regulate Shh signaling in the
spinal cord, primarily by preventing Gli2 activation in
the absence of Shh ligand. Rab23 also regulates a step
in the cytoplasmic signal transduction pathway that
mediates the effect of Smoothened (one of two integral
membrane proteins that are essential components of the
Shh signaling pathway in vertebrates). In humans, Rab23
is expressed in the retina. Mice contain an isoform that
shares 93% sequence identity with the human Rab23 and an
alternative splicing isoform that is specific to the
brain. This isoform causes the murine open brain
phenotype, indicating it may have a role in the
development of the central nervous system. GTPase
activating proteins (GAPs) interact with GTP-bound Rab
and accelerate the hydrolysis of GTP to GDP. Guanine
nucleotide exchange factors (GEFs) interact with
GDP-bound Rabs to promote the formation of the GTP-bound

expression. Rab3A, Rab3B, and Rab3C localized to
synaptic and secretory vesicles; Rab3D was expressed at
high levels only in adipose tissue, exocrine glands, and
the endocrine pituitary, where it is localized to

(septum-promoting GTPase) was first identified in the

formation in the septation initiation network (SIN)
through the cdc7 protein kinase. Spg1p is an essential
gene that localizes to the spindle pole bodies. When

Growth inhibitor) and Ras-like 11 are members of a novel
subfamily of Ras that were identified based on their
behavior in breast and prostate tumors, respectively.
RERG expression was decreased or lost in a significant
fraction of primary human breast tumors that lack
estrogen receptor and are correlated with poor clinical
prognosis. Elevated RERG expression correlated with
favorable patient outcome in a breast tumor subtype that
is positive for estrogen receptor expression. In
contrast to most Ras proteins, RERG overexpression
inhibited the growth of breast tumor cells in vitro and
in vivo. RasL11 was found to be ubiquitously expressed
in human tissue, but down-regulated in prostate tumors.
Both RERG and RasL11 lack the C-terminal CaaX
prenylation motif, where a = an aliphatic amino acid and
X = any amino acid, and are localized primarily in the
cytoplasm. Both are believed to have tumor suppressor

>gnl|CDD|133318 cd04118, Rab24, Rab GTPase family 24 (Rab24). Rab24 is distinct
from other Rabs in several ways. It exists primarily in
the GTP-bound state, having a low intrinsic GTPase
activity; it is not efficiently geranyl-geranylated at
the C-terminus; it does not form a detectable complex
with Rab GDP-dissociation inhibitors (GDIs); and it has
recently been shown to undergo tyrosine phosphorylation
when overexpressed in vitro. The specific function of
Rab24 still remains unknown. It is found in a transport
route between ER-cis-Golgi and late endocytic
compartments. It is putatively involved in an autophagic
pathway, possibly directing misfolded proteins in the ER
to degradative pathways. GTPase activating proteins
(GAPs) interact with GTP-bound Rab and accelerate the
hydrolysis of GTP to GDP. Guanine nucleotide exchange
factors (GEFs) interact with GDP-bound Rabs to promote
the formation of the GTP-bound state. Rabs are further
regulated by guanine nucleotide dissociation inhibitors
(GDIs), which facilitate Rab recycling by masking
C-terminal lipid binding and promoting cytosolic
localization. Most Rab GTPases contain a lipid
modification site at the C-terminus, with sequence
motifs CC, CXC, or CCX. Lipid binding is essential for
membrane attachment, a key feature of most Rab proteins.

(Rab36). Rab34/Rab36 subfamily. Rab34, found primarily
in the Golgi, interacts with its effector,
Rab-interacting lysosomal protein (RILP). This enables
its participation in microtubular
dynenin-dynactin-mediated repositioning of lysosomes
from the cell periphery to the Golgi. A Rab34 (Rah)
isoform that lacks the consensus GTP-binding region has
been identified in mice. This isoform is associated with
membrane ruffles and promotes macropinosome formation.
Rab36 has been mapped to human chromosome 22q11.2, a
region that is homozygously deleted in malignant
rhabdoid tumors (MRTs). However, experimental
assessments do not implicate Rab36 as a tumor suppressor
that would enable tumor formation through a
loss-of-function mechanism. GTPase activating proteins
(GAPs) interact with GTP-bound Rab and accelerate the
hydrolysis of GTP to GDP. Guanine nucleotide exchange
factors (GEFs) interact with GDP-bound Rabs to promote
the formation of the GTP-bound state. Rabs are further

subfamily includes Rhes (Ras homolog enriched in
striatum) and Dexras1/AGS1 (activator of G-protein
signaling 1). These proteins are homologous, but exhibit
significant differences in tissue distribution and
subcellular localization. Rhes is found primarily in the
striatum of the brain, but is also expressed in other
areas of the brain, such as the cerebral cortex,
hippocampus, inferior colliculus, and cerebellum. Rhes
expression is controlled by thyroid hormones. In rat
PC12 cells, Rhes is farnesylated and localizes to the
plasma membrane. Rhes binds and activates PI3K, and
plays a role in coupling serpentine membrane receptors
with heterotrimeric G-protein signaling. Rhes has
recently been shown to be reduced under conditions of
dopamine supersensitivity and may play a role in
determining dopamine receptor sensitivity. Dexras1/AGS1
is a dexamethasone-induced Ras protein that is expressed
primarily in the brain, with low expression levels in
other tissues. Dexras1 localizes primarily to the
cytoplasm, and is a critical regulator of the circadian
master clock to photic and nonphotic input. Most Ras
proteins contain a lipid modification site at the
C-terminus, with a typical sequence motif CaaX, where a
= an aliphatic amino acid and X = any amino acid. Lipid
binding is essential for membrane attachment, a key
feature of most Ras proteins.

GTPases. RGK subfamily. The RGK (Rem, Rem2, Rad,
Gem/Kir) subfamily of Ras GTPases are expressed in a
tissue-specific manner and are dynamically regulated by
transcriptional and posttranscriptional mechanisms in
response to environmental cues. RGK proteins bind to the
beta subunit of L-type calcium channels, causing
functional down-regulation of these voltage-dependent
calcium channels, and either termination of
calcium-dependent secretion or modulation of electrical
conduction and contractile function. Inhibition of
L-type calcium channels by Rem2 may provide a mechanism
for modulating calcium-triggered exocytosis in
hormone-secreting cells, and has been proposed to
influence the secretion of insulin in pancreatic beta
cells. RGK proteins also interact with and inhibit the
Rho/Rho kinase pathway to modulate remodeling of the
cytoskeleton. Two characteristics of RGK proteins cited
in the literature are N-terminal and C-terminal
extensions beyond the GTPase domain typical of Ras
superfamily members. The N-terminal extension is not
conserved among family members; the C-terminal extension
is reported to be conserved among the family and lack
the CaaX prenylation motif typical of

family. RRP22 (Ras-related protein on chromosome 22)
subfamily consists of proteins that inhibit cell growth
and promote caspase-independent cell death. Unlike most
Ras proteins, RRP22 is down-regulated in many human
tumor cells due to promoter methylation. RRP22 localizes
to the nucleolus in a GTP-dependent manner, suggesting a
novel function in modulating transport of nucleolar
components. Most Ras proteins contain a lipid
modification site at the C-terminus, with a typical
sequence motif CaaX, where a = an aliphatic amino acid
and X = any amino acid. Lipid binding is essential for
membrane attachment, a key feature of most Ras proteins.
Like most Ras family proteins, RRP22 is farnesylated.

Rab40b and Rab40c. The Rab40 subfamily contains Rab40a,
Rab40b, and Rab40c, which are all highly homologous. In
rat, Rab40c is localized to the perinuclear recycling
compartment (PRC), and is distributed in a
tissue-specific manor, with high expression in brain,
heart, kidney, and testis, low expression in lung and
liver, and no expression in spleen and skeletal muscle.
Rab40c is highly expressed in differentiated
oligodendrocytes but minimally expressed in
oligodendrocyte progenitors, suggesting a role in the
vesicular transport of myelin components. Unlike most
other Ras-superfamily proteins, Rab40c was shown to have
a much lower affinity for GTP, and an affinity for GDP
that is lower than for GTP. GTPase activating proteins
(GAPs) interact with GTP-bound Rab and accelerate the
hydrolysis of GTP to GDP. Guanine nucleotide exchange
factors (GEFs) interact with GDP-bound Rabs to promote
the formation of the GTP-bound state. Rabs are further
regulated by guanine nucleotide dissociation inhibitors
(GDIs), which facilitate Rab recycling by masking
C-terminal lipid binding and promoting cytosolic
localization. Most Rab GTPases contain a lipid
modification site at the C-terminus, with sequence
motifs CC, CXC, or CCX. Lipid binding is essential for
membrane attachment, a key feature of most Rab proteins.

First identified in maize, Rab28 has been shown to be a
late embryogenesis-abundant (Lea) protein that is
regulated by the plant hormone abcisic acid (ABA). In
Arabidopsis, Rab28 is expressed during embryo
development and is generally restricted to provascular
tissues in mature embryos. Unlike maize Rab28, it is not
ABA-inducible. Characterization of the human Rab28
homolog revealed two isoforms, which differ by a 95-base
pair insertion, producing an alternative sequence for
the 30 amino acids at the C-terminus. The two human
isoforms are presumably the result of alternative
splicing. Since they differ at the C-terminus but not in
the GTP-binding region, they are predicted to be
targeted to different cellular locations. GTPase
activating proteins (GAPs) interact with GTP-bound Rab
and accelerate the hydrolysis of GTP to GDP. Guanine
nucleotide exchange factors (GEFs) interact with
GDP-bound Rabs to promote the formation of the GTP-bound
state. Rabs are further regulated by guanine nucleotide

centaurins (alpha, beta, gamma, and delta) are large,
multi-domain proteins that all contain an ArfGAP domain
and ankyrin repeats, and in some cases, numerous
additional domains. Centaurin gamma contains an
additional GTPase domain near its N-terminus. The
specific function of this GTPase domain has not been
well characterized, but centaurin gamma 2 (CENTG2) may
play a role in the development of autism. Centaurin
gamma 1 is also called PIKE (phosphatidyl inositol (PI)
3-kinase enhancer) and centaurin gamma 2 is also known
as AGAP (ArfGAP protein with a GTPase-like domain,
ankyrin repeats and a Pleckstrin homology domain) or
GGAP. Three isoforms of PIKE have been identified.
PIKE-S (short) and PIKE-L (long) are brain-specific
isoforms, with PIKE-S restricted to the nucleus and
PIKE-L found in multiple cellular compartments. A third
isoform, PIKE-A was identified in human glioblastoma
brain cancers and has been found in various tissues.
GGAP has been shown to have high GTPase activity due to
a direct intramolecular interaction between the
N-terminal GTPase domain and the C-terminal ArfGAP
domain. In human tissue, AGAP mRNA was detected in
skeletal muscle, kidney, placenta, brain, heart, colon,
and lung. Reduced expression levels were also observed
in the spleen, liver, and small intestine.

small GTPases. Arf proteins are activators of
phospholipase D isoforms. Unlike Ras proteins they lack
cysteine residues at their C-termini and therefore are
unlikely to be prenylated. Arfs are N-terminally
myristoylated. Members of the Arf family are regulators
of vesicle formation in intracellular traffic that
interact reversibly with membranes of the secretory and

front-back communication from N-terminus to the
nucleotide binding site. Arf-like (Arl) proteins are
close relatives of the Arf, but only Arl1 has been shown
to function in membrane traffic like the Arf proteins.
Arl2 has an unrelated function in the folding of native
tubulin, and Arl4 may function in the nucleus. Most
other Arf family proteins are so far relatively poorly
characterized. Thus, despite their significant sequence
homologies, Arf family proteins may regulate unrelated
functions.

ARD1 (ADP-ribosylation factor domain protein 1) is an
unusual member of the Arf family. In addition to the
C-terminal Arf domain, ARD1 has an additional 46-kDa
N-terminal domain that contains a RING finger domain,
two predicted B-Boxes, and a coiled-coil protein
interaction motif. This domain belongs to the TRIM
(tripartite motif) or RBCC (RING, B-Box, coiled-coil)
family. Like most Arfs, the ARD1 Arf domain lacks
detectable GTPase activity. However, unlike most Arfs,
the full-length ARD1 protein has significant GTPase
activity due to the GAP (GTPase-activating protein)
activity exhibited by the 46-kDa N-terminal domain. The
GAP domain of ARD1 is specific for its own Arf domain
and does not bind other Arfs. The rate of GDP
dissociation from the ARD1 Arf domain is slowed by the
adjacent 15 amino acids, which act as a GDI
(GDP-dissociation inhibitor) domain. ARD1 is
ubiquitously expressed in cells and localizes to the
Golgi and to the lysosomal membrane. Two Tyr-based
motifs in the Arf domain are responsible for Golgi
localization, while the GAP domain controls lysosomal
localization.

Era contains two domains: the N-terminal GTPase domain
and a C-terminal domain KH domain that is critical for

Arf6 (ADP ribosylation factor 6) proteins localize to
the plasma membrane, where they perform a wide variety
of functions. In its active, GTP-bound form, Arf6 is
involved in cell spreading, Rac-induced formation of
plasma membrane ruffles, cell migration, wound healing,
and Fc-mediated phagocytosis. Arf6 appears to change
the actin structure at the plasma membrane by
activating Rac, a Rho family protein involved in
membrane ruffling. Arf6 is required for and enhances
Rac formation of ruffles. Arf6 can regulate dendritic
branching in hippocampal neurons, and in yeast it
localizes to the growing bud, where it plays a role in
polarized growth and bud site selection. In leukocytes,
Arf6 is required for chemokine-stimulated migration
across endothelial cells. Arf6 also plays a role in
down-regulation of beta2-adrenergic receptors and
luteinizing hormone receptors by facilitating the
release of sequestered arrestin to allow endocytosis.
Arf6 is believed to function at multiple sites on the
plasma membrane through interaction with a specific set
of GEFs, GAPs, and effectors. Arf6 has been implicated
in breast cancer and melanoma cell invasion, and in
actin remodelling at the invasion site of Chlamydia
infection.

Arf family protein that differs from most Arf family
members in the N-terminal extension. In is inactive,
GDP-bound form, the N-terminal extension forms an
elongated loop that is hydrophobically anchored into the

this region might form a helix in the GTP-bound form.
The delta subunit of the rod-specific cyclic GMP
phosphodiesterase type 6 (PDEdelta) is an Arl3 effector.
Arl3 binds microtubules in a regulated manner to alter
specific aspects of cytokinesis via interactions with
retinitis pigmentosa 2 (RP2). It has been proposed that
RP2 functions in concert with Arl3 to link the cell
membrane and the cytoskeleton in photoreceptors as part
of the cell signaling or vesicular transport machinery.
In mice, the absence of Arl3 is associated with abnormal

>gnl|CDD|176124 cd08433, PBP2_Nac, The C-teminal substrate binding domain of
LysR-like nitrogen assimilation control (NAC) protein,
contains the type 2 periplasmic binding fold. The NAC
is a LysR-type transcription regulator that activates
expression of operons such as hut (histidine
utilization) and ure (urea utilization), allowing use of
non-preferred (poor) nitrogen sources, and represses
expression of operons, such as glutamate dehydrogenase
(gdh), allowing assimilation of the preferred nitrogen
source. The expression of the nac gene is fully
dependent on the nitrogen regulatory system (NTR) and
the sigma54-containing RNA polymerase (sigma54-RNAP). In
response to nitrogen starvation, NTR system activates
the expression of nac, and NAC activates the expression
of hut, ure, and put (proline utilization). NAC is not
involved in the transcription of Sigma70-RNAP operons
such as glnA, which directly respond by the NTR system,
but activates the transcription of sigma70-RNAP
dependent operons such as hut. Hence, NAC allows the
coupling of sigma70-RNAP dependent operons to the
sigma54-RNAP dependent NTR system. This
substrate-binding domain has significant homology to the
type 2 periplasmic binding proteins (PBP2), which are
responsible for the uptake of a variety of substrates
such as phosphate, sulfate, polysaccharides,
lysine/arginine/ornithine, and histidine. The PBP2 bind
their ligand in the cleft between these domains in a
manner resembling a Venus flytrap. After binding their
specific ligand with high affinity, they can interact
with a cognate membrane transport complex comprised of
two integral membrane domains and two cytoplasmically
located ATPase domains. This interaction triggers the
ligand translocation across the cytoplasmic membrane
energized by ATP hydrolysis.

inactivation seems to occur most frequently through

typically a combination of a hypomorphic polymorphism
plus loss of heterozygosity. In a case of thyroid

promoter hypermethylation. The nonsense polymorphism
Trp149Stop occurs with significantly greater frequency
in familial cancer cases than in sporadic cancer cases,
and the Cys148Arg polymorphism is associated with an

ADP-ribosylation factor-5 (Arf5). The Arf1-Arf5-like
subfamily contains Arf1, Arf2, Arf3, Arf4, Arf5, and
related proteins. Arfs1-5 are soluble proteins that are
crucial for assembling coat proteins during vesicle
formation. Each contains an N-terminal myristoylated
amphipathic helix that is folded into the protein in
the GDP-bound state. GDP/GTP exchange exposes the
helix, which anchors to the membrane. Following GTP
hydrolysis, the helix dissociates from the membrane and
folds back into the protein. A general feature of
Arf1-5 signaling may be the cooperation of two Arfs at
the same site. Arfs1-5 are generally considered to be
interchangeable in function and location, but some
specific functions have been assigned. Arf1 localizes
to the early/cis-Golgi, where it is activated by GBF1
and recruits the coat protein COPI. It also localizes
to the trans-Golgi network (TGN), where it is activated
by BIG1/BIG2 and recruits the AP1, AP3, AP4, and GGA
proteins. Humans, but not rodents and other lower
eukaryotes, lack Arf2. Human Arf3 shares 96% sequence
identity with Arf1 and is believed to generally
function interchangeably with Arf1. Human Arf4 in the
activated (GTP-bound) state has been shown to interact
with the cytoplasmic domain of epidermal growth factor
receptor (EGFR) and mediate the EGF-dependent
activation of phospholipase D2 (PLD2), leading to
activation of the activator protein 1 (AP-1)
transcription factor. Arf4 has also been shown to
recognize the C-terminal sorting signal of rhodopsin
and regulate its incorporation into specialized
post-Golgi rhodopsin transport carriers (RTCs). There
is some evidence that Arf5 functions at the early-Golgi
and the trans-Golgi to affect Golgi-associated
alpha-adaptin homology Arf-binding proteins (GGAs).

>gnl|CDD|133353 cd04153, Arl5_Arl8, Arf-like 5 (Arl5) and 8 (Arl8) GTPases.
Arl5/Arl8 subfamily. Arl5 (Arf-like 5) and Arl8, like
Arl4 and Arl7, are localized to the nucleus and
nucleolus. Arl5 is developmentally regulated during
embryogenesis in mice. Human Arl5 interacts with the
heterochromatin protein 1-alpha (HP1alpha), a
nonhistone chromosomal protein that is associated with
heterochromatin and telomeres, and prevents telomere
fusion. Arl5 may also play a role in embryonic nuclear
dynamics and/or signaling cascades. Arl8 was identified
from a fetal cartilage cDNA library. It is found in
brain, heart, lung, cartilage, and kidney. No function
has been assigned for Arl8 to date.

>gnl|CDD|206684 cd01897, NOG, Nucleolar GTP-binding protein (NOG). NOG1 is a
nucleolar GTP-binding protein present in eukaryotes
ranging from trypanosomes to humans. NOG1 is
functionally linked to ribosome biogenesis and found in
association with the nuclear pore complexes and
identified in many preribosomal complexes. Thus, defects
in NOG1 can lead to defects in 60S biogenesis. The S.
cerevisiae NOG1 gene is essential for cell viability,
and mutations in the predicted G motifs abrogate
function. It is a member of the ODN family of
GTP-binding proteins that also includes the bacterial
Obg and DRG proteins.

>gnl|CDD|206646 cd00880, Era_like, E. coli Ras-like protein (Era)-like GTPase. The
Era (E. coli Ras-like protein)-like family includes
several distinct subfamilies (TrmE/ThdF, FeoB, YihA
(EngB), Era, and EngA/YfgK) that generally show sequence
conservation in the region between the Walker A and B
motifs (G1 and G3 box motifs), to the exclusion of other
GTPases. TrmE is ubiquitous in bacteria and is a
widespread mitochondrial protein in eukaryotes, but is
absent from archaea. The yeast member of TrmE family,
MSS1, is involved in mitochondrial translation;
bacterial members are often present in
translation-related operons. FeoB represents an unusual
adaptation of GTPases for high-affinity iron (II)
transport. YihA (EngB) family of GTPases is typified by
the E. coli YihA, which is an essential protein involved
in cell division control. Era is characterized by a
distinct derivative of the KH domain (the pseudo-KH
domain) which is located C-terminal to the GTPase
domain. EngA and its orthologs are composed of two
GTPase domains and, since the sequences of the two
domains are more similar to each other than to other
GTPases, it is likely that an ancient gene duplication,
rather than a fusion of evolutionarily distinct GTPases,
gave rise to this family.

alkylhydroperoxide reductase subunit C) is one subunit
of a two-subunit complex with subunit F(TIGR03140).
Usually these are found as an apparent operon. The gene
has been characterized in Bacteroides fragilis where it
is important in oxidative stress defense. This gene
contains two invariant cysteine residues, one near the
N-terminus and one near the C-terminus, each followed
immediately by a proline residue [Cellular processes,
