>gnl|CDD|133311 cd04111, Rab39, Rab GTPase family 39 (Rab39). Found in eukaryotes,
Rab39 is mainly found in epithelial cell lines, but is
distributed widely in various human tissues and cell
lines. It is believed to be a novel Rab protein involved
in regulating Golgi-associated vesicular transport
during cellular endocytosis. 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.

>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.

>gnl|CDD|206660 cd01868, Rab11_like, Rab GTPase family 11 (Rab11)-like includes
Rab11a, Rab11b, and Rab25. Rab11a, Rab11b, and Rab25
are closely related, evolutionary conserved Rab proteins
that are differentially expressed. Rab11a is
ubiquitously synthesized, Rab11b is enriched in brain
and heart and Rab25 is only found in epithelia. Rab11/25
proteins seem to regulate recycling pathways from
endosomes to the plasma membrane and to the trans-Golgi
network. Furthermore, Rab11a is thought to function in
the histamine-induced fusion of tubulovesicles
containing H+, K+ ATPase with the plasma membrane in
gastric parietal cells and in insulin-stimulated
insertion of GLUT4 in the plasma membrane of
cardiomyocytes. Overexpression of Rab25 has recently
been observed in ovarian cancer and breast cancer, and
has been correlated with worsened outcomes in both
diseases. In addition, Rab25 overexpression has also
been observed in prostate cancer, transitional cell
carcinoma of the bladder, and invasive breast tumor
cells. GTPase activating proteins (GAPs) interact with
GTP-bound Rab and accelerate the hydrolysis of GTP to

has been implicated in numerous functions within the
cell. It helps regulate endocytosis through the sorting,
recycling, and degradation of early endosomes. Mammalian
Rab4 is involved in the regulation of many surface
proteins including G-protein-coupled receptors,
transferrin receptor, integrins, and surfactant protein
A. Experimental data implicate Rab4 in regulation of the
recycling of internalized receptors back to the plasma
membrane. It is also believed to influence
receptor-mediated antigen processing in B-lymphocytes,
in calcium-dependent exocytosis in platelets, in
alpha-amylase secretion in pancreatic cells, and in
insulin-induced translocation of Glut4 from internal
vesicles to the cell surface. Rab4 is known to share
effector proteins with Rab5 and Rab11. GTPase activating
proteins (GAPs) interact with GTP-bound Rab and
accelerate the hydrolysis of GTP to GDP. Guanine

(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
proteins, related in sequence to Sec4p of Saccharomyces
cerevisiae but closer to mammalian Rab8. GTPase

subfamily consists of Rab27a and its highly homologous
isoform, Rab27b. Unlike most Rab proteins whose
functions remain poorly defined, Rab27a has many known
functions. Rab27a has multiple effector proteins, and
depending on which effector it binds, Rab27a has
different functions as well as tissue distribution
and/or cellular localization. Putative functions have
been assigned to Rab27a when associated with the
effector proteins Slp1, Slp2, Slp3, Slp4, Slp5, DmSlp,
rabphilin, Dm/Ce-rabphilin, Slac2-a, Slac2-b, Slac2-c,
Noc2, JFC1, and Munc13-4. Rab27a has been associated
with several human diseases, including hemophagocytic
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
localized to the secretory granules of pancreatic beta
cells, it is believed to mediate glucose-stimulated
insulin secretion, making it a potential target for

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
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.

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

exclusively in fungi, was first identified in Ustilago
maydis. In U. maydis, Ras2 is regulated by Sql2, a
protein that is homologous to GEFs (guanine nucleotide
exchange factors) of the CDC25 family. Ras2 has been
shown to induce filamentous growth, but the signaling

>gnl|CDD|206694 cd04109, Rab28, Rab GTPase family 28 (Rab28). Rab28 subfamily.
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
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.

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
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

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.

RERG expression was decreased or lost in a significant

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.

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.

polarized kidney tubule and intestinal epithelial cells,
and in non-polarized cells. It also localizes to
vesico-tubular structures below the apical brush border
of renal proximal tubule cells and in the apical region
of duodenal epithelial cells. Rab20 has also been shown

of V-ATPase traffic in specific portions of the nephron.
It was also shown to be one of several proteins whose

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.

distinct from other Rabs, and have been termed Rab-like.
RabL2 contains RabL2a and RabL2b, two very similar Rab

RabL2b maps to the subtelomeric region of chromosome
22q13.3 and RabL2a maps to 2q13, a region that suggests

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.
Due to the presence of truncated sequences in this CD,
the lipid modification site is not available for

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

(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
GTP-bound, it binds cdc7 and causes it to translocate to
spindle poles. Sid4p (septation initiation defective) is
required for localization of Spg1p to the spindle pole
body, and the ability of Spg1p to promote septum
formation from any point in the cell cycle depends on
Sid4p. Spg1p is negatively regulated by Byr4 and cdc16,
which form a two-component GTPase activating protein
(GAP) for Spg1p. The existence of a SIN-related pathway
in plants has been proposed. GTPase activating proteins

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
feature of most Ras proteins. Due to the presence of
truncated sequences in this CD, the lipid modification
site is not available for annotation.

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

feature of most Rho proteins. RhoA and RhoC are observed
only in geranylgeranylated forms; however, RhoB can be
present in palmitoylated, farnesylated, and

relevant for tumor progression and invasiveness;
however, RhoB has recently been suggested to be a tumor
suppressor. Due to the presence of truncated sequences

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

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

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

myristoylated. Members of the Arf family are regulators
of vesicle formation in intracellular traffic that
interact reversibly with membranes of the secretory and

Arl2 has an unrelated function in the folding of native

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
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.

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

protein that has been shown to induce microspike
formation and neurite outgrowth in vitro. Its expression
changes dramatically after peripheral nerve injury,
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

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

(MgcRacGAP), where it localizes to the Golgi-derived
pro-acrosomal vesicle. Most Rho proteins contain a lipid

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

functions as a tumor suppressor gene in several human
cancers. ARLTS1 is a low-penetrance suppressor that
accounts for a small percentage of familial melanoma or

inactivation seems to occur most frequently through
biallelic down-regulation by hypermethylation of the

typically a combination of a hypomorphic polymorphism
plus loss of heterozygosity. In a case of thyroid
adenoma, ARLTS1 alterations were polymorphism plus
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

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

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

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)

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

membrane surface; however, it has been proposed that
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
epithelial cell proliferation and cyst formation.

heterochromatin and telomeres, and prevents telomere
fusion. Arl5 may also play a role in embryonic nuclear

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).

coats involved in export of cargo from the ER. The
GTPase activity of Sar1 functions as a molecular switch
to control protein-protein and protein-lipid
interactions that direct vesicle budding from the ER.
Activation of the GDP to the GTP-bound form of Sar1
involves the membrane-associated guanine nucleotide
exchange factor (GEF) Sec12. Sar1 is unlike all Ras
superfamily GTPases that use either myristoyl or prenyl
groups to direct membrane association and function, in
that Sar1 lacks such modification. Instead, Sar1
contains a unique nine-amino-acid N-terminal extension.
This extension contains an evolutionarily conserved
cluster of bulky hydrophobic amino acids, referred to as
the Sar1-N-terminal activation recruitment (STAR) motif.
The STAR motif mediates the recruitment of Sar1 to ER
membranes and facilitates its interaction with mammalian
Sec12 GEF leading to activation.

Arl1 (Arf-like 1) localizes to the Golgi complex, where
it is believed to recruit effector proteins to the
trans-Golgi network. Like most members of the Arf
family, Arl1 is myristoylated at its N-terminal helix
and mutation of the myristoylation site disrupts Golgi
targeting. In humans, the Golgi-localized proteins
golgin-97 and golgin-245 have been identified as Arl1
effectors. Golgins are large coiled-coil proteins found
in the Golgi, and these golgins contain a C-terminal
GRIP domain, which is the site of Arl1 binding.
Additional Arl1 effectors include the GARP
(Golgi-associated retrograde protein)/VFT (Vps53)
vesicle-tethering complex and Arfaptin 2. Arl1 is not
required for exocytosis, but appears necessary for
trafficking from the endosomes to the Golgi. In

the host-bloodstream form of Trypanosoma brucei, Arl1
is essential for viability.

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

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

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.

>gnl|CDD|206680 cd01893, Miro1, Mitochondrial Rho family 1 (Miro1), N-terminal.
Miro1 subfamily. Miro (mitochondrial Rho) proteins have
tandem GTP-binding domains separated by a linker region
containing putative calcium-binding EF hand motifs.
Genes encoding Miro-like proteins were found in several
eukaryotic organisms. This CD represents the N-terminal
GTPase domain of Miro proteins. These atypical Rho
GTPases have roles in mitochondrial homeostasis and
apoptosis. Most Rho proteins contain a lipid
modification site at the C-terminus; however, Miro is
one of few Rho subfamilies that lack this feature.

Arl2l1 (Arl2-like protein 1) and Arl13 form a subfamily
of the Arf family of small GTPases. Arl2l1 was
identified in human cells during a search for the
gene(s) responsible for Bardet-Biedl syndrome (BBS).
Like Arl6, the identified BBS gene, Arl2l1 is proposed
to have cilia-specific functions. Arl13 is found on the
X chromosome, but its expression has not been confirmed;
it may be a pseudogene.

>gnl|CDD|206742 cd09915, Rag, Rag GTPase subfamily of Ras-related GTPases. Rag
GTPases (ras-related GTP-binding proteins) constitute a
unique subgroup of the Ras superfamily, playing an
essential role in regulating amino acid-induced target
of rapamycin complex 1 (TORC1) kinase signaling,
exocytic cargo sorting at endosomes, and epigenetic
control of gene expression. This subfamily consists of
RagA and RagB as well as RagC and RagD that are closely
related. Saccharomyces cerevisiae encodes single
orthologs of metazoan RagA/B and RagC/D, Gtr1 and Gtr2,
respectively. Dimer formation is important for their
cellular function; these domains form heterodimers, as
RagA or RagB dimerizes with RagC or RagD, and
similarly, Gtr1 dimerizes with Gtr2. In response to
amino acids, the Rag GTPases guide the TORC1 complex to
activate the platform containing Rheb proto-oncogene by
driving the relocalization of mTORC1 from discrete
locations in the cytoplasm to a late endosomal and/or
lysosomal compartment that is Rheb-enriched and
contains Rab-7.
