>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|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

>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

>gnl|CDD|206703 cd04131, Rnd, Rho family GTPase subfamily Rnd includes Rnd1/Rho6,
Rnd2/Rho7, and Rnd3/RhoE/Rho8. The Rnd subfamily
contains Rnd1/Rho6, Rnd2/Rho7, and Rnd3/RhoE/Rho8. These
novel Rho family proteins have substantial structural
differences compared to other Rho members, including N-
and C-terminal extensions relative to other Rhos.
Rnd3/RhoE is farnesylated at the C-terminal prenylation
site, unlike most other Rho proteins that are
geranylgeranylated. In addition, Rnd members are unable
to hydrolyze GTP and are resistant to GAP activity. They
are believed to exist only in the GTP-bound
conformation, and are antagonists of RhoA activity. 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

>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

plays a role in cell morphogenesis, control of cell wall
integrity, control of growth polarity, and maintenance
of growth direction. Rho2 activates the protein kinase C
homolog Pck2, and Pck2 controls Mok1, the major (1-3)
alpha-D-glucan synthase. Together with Rho1 (RhoA), Rho2
regulates the construction of the cell wall. Unlike
Rho1, Rho2 is not an essential protein, but its
overexpression is lethal. 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 proper intracellular localization via
membrane attachment. As with other Rho family GTPases,
the GDP/GTP cycling is regulated by GEFs (guanine
nucleotide exchange factors), GAPs (GTPase-activating
proteins) and GDIs (guanine nucleotide dissociation
inhibitors).

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|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
annotation.

>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

>gnl|CDD|206707 cd04135, Tc10, Rho GTPase TC10 (Tc10). TC10 is a Rho family
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
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.

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
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|206736 cd04173, Rnd2_Rho7, Rnd2/Rho7 GTPases. Rnd2/Rho7 is a member of
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
pro-acrosomal vesicle. 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

>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.
Due to the presence of truncated sequences in this CD,

the novel Rho subfamily Rnd, together with Rnd2/Rho7 and
Rnd3/RhoE/Rho8. Rnd1/Rho6 binds GTP but does not
hydrolyze it to GDP, indicating that it is
constitutively active. In rat, Rnd1/Rho6 is highly
expressed in the cerebral cortex and hippocampus during
synapse formation, and plays a role in spine formation.
Rnd1/Rho6 is also expressed in the liver and in

myometrial cells during pregnancy. Like Rnd3/RhoE/Rho8,
Rnd1/Rho6 is believed to function as an antagonist to
RhoA. Most Rho proteins contain a lipid modification

>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.

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
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,

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.

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

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

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.

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

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

>gnl|CDD|206655 cd01862, Rab7, Rab GTPase family 7 (Rab7). Rab7 subfamily. Rab7 is
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
the lytic compartment. Mammalian Rab7 is also proposed
to function as a tumor suppressor. 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.

>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
feature of most Ras proteins. Due to the presence of
truncated sequences in this CD, the lipid modification

Ras-like protein in neurons (Rin) and Ras-related
protein which interacts with calmodulin (Ric). Rit
(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.

RERG expression was decreased or lost in a significant

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

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.

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

and accelerate the hydrolysis of GTP to GDP. Guanine

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
endocytic compartments in a GTP-dependent manner. They
depart from other small GTP-binding proteins by a unique
structural device, interswitch toggle, that implements
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

(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

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

factors (GEFs) interact with GDP-bound Rabs to promote
the formation of the GTP-bound state. Rabs are further

C-terminal lipid binding and promoting cytosolic
localization.

several Rab proteins that appear to be restricted in
expression to the apical domain of murine polarized
epithelial cells. It is expressed on the apical side of
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
to colocalize with vacuolar H+-ATPases (V-ATPases) in
mouse kidney cells, suggesting a role in the regulation
of V-ATPase traffic in specific portions of the nephron.
It was also shown to be one of several proteins whose
expression is upregulated in human myelodysplastic
syndrome (MDS) patients. 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

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.

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
membrane-associated Ras proteins. However, a putative
CaaX motif has been identified in the alignment of the
C-terminal residues of this CD.

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
familial chronic lymphocytic leukemia (CLL). ARLTS1
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
increase in high-risk familial breast cancer.

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

>gnl|CDD|206716 cd04149, Arf6, ADP ribosylation factor 6 (Arf6). Arf6 subfamily.
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.

>gnl|CDD|206645 cd00879, Sar1, Sar1 is an essential component of COPII vesicle
coats. Sar1 is an essential component of COPII vesicle
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.

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.

subfamily of the Arf family of small GTPases. Arl6
expression is limited to the brain and kidney in adult
mice, but it is expressed in the neural plate and
somites during embryogenesis, suggesting a possible role
for Arl6 in early development. Arl6 is also believed to
have a role in cilia or flagella function. Several
proteins have been identified that bind Arl6, including
Arl6 interacting protein (Arl6ip), and SEC61beta, a
subunit of the heterotrimeric conducting channel SEC61p.
Based on Arl6 binding to these effectors, Arl6 is also
proposed to play a role in protein transport, membrane
trafficking, or cell signaling during hematopoietic
maturation. At least three specific homozygous Arl6
mutations in humans have been found to cause
Bardet-Biedl syndrome, a disorder characterized by
obesity, retinopathy, polydactyly, renal and cardiac
malformations, learning disabilities, and
hypogenitalism. Older literature suggests that Arl6 is a
part of the Arl4/Arl7 subfamily, but analyses based on
more recent sequence data place Arl6 in its own
subfamily.

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
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.

>gnl|CDD|206739 cd09912, DLP_2, Dynamin-like protein including dynamins,
mitofusins, and guanylate-binding proteins. The dynamin
family of large mechanochemical GTPases includes the
classical dynamins and dynamin-like proteins (DLPs) that
are found throughout the Eukarya. This family also
includes bacterial DLPs. These proteins catalyze
membrane fission during clathrin-mediated endocytosis.
Dynamin consists of five domains; an N-terminal G domain
that binds and hydrolyzes GTP, a middle domain (MD)
involved in self-assembly and oligomerization, a
pleckstrin homology (PH) domain responsible for
interactions with the plasma membrane, GED, which is
also involved in self-assembly, and a proline arginine
rich domain (PRD) that interacts with SH3 domains on
accessory proteins. To date, three vertebrate dynamin
genes have been identified; dynamin 1, which is brain
specific, mediates uptake of synaptic vesicles in
presynaptic terminals; dynamin-2 is expressed
ubiquitously and similarly participates in membrane
fission; mutations in the MD, PH and GED domains of
dynamin 2 have been linked to human diseases such as
Charcot-Marie-Tooth peripheral neuropathy and rare forms
of centronuclear myopathy. Dynamin 3 participates in
megakaryocyte progenitor amplification, and is also
involved in cytoplasmic enlargement and the formation of
the demarcation membrane system. This family also
includes mitofusins (MFN1 and MFN2 in mammals) that are
involved in mitochondrial fusion. Dynamin oligomerizes
into helical structures around the neck of budding
vesicles in a GTP hydrolysis-dependent manner.

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

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.

>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.

with an N-terminal hydrophobic signal sequence that
binds SRP54, a component of the SRP. SRP directs
targeting of the ribosome-nascent chain complex (RNC) to
the ER membrane via interaction with the SR, which is
localized to the ER membrane. The RNC is then
transferred to the protein-conducting channel, or
translocon, which facilitates polypeptide translation
across the ER membrane or integration into the ER
membrane. SR-beta is found only in eukaryotes; it is
believed to control the release of the signal sequence
from SRP54 upon binding of the ribosome to the
translocon. High expression of SR-beta has been observed
in human colon cancer, suggesting it may play a role in
the development of this type of cancer.

>gnl|CDD|233986 TIGR02729, Obg_CgtA, Obg family GTPase CgtA. This model describes
a univeral, mostly one-gene-per-genome GTP-binding
protein that associates with ribosomal subunits and
appears to play a role in ribosomal RNA maturation. This
GTPase, related to the nucleolar protein Obg, is
designated CgtA in bacteria. Mutations in this gene are
pleiotropic, but it appears that effects on cellular
functions such as chromosome partition may be secondary
to the effect on ribosome structure. Recent work done in
Vibrio cholerae shows an essential role in the stringent
response, in which RelA-dependent ability to synthesize
the alarmone ppGpp is required for deletion of this
GTPase to be lethal [Protein synthesis, Other].

>gnl|CDD|206677 cd01890, LepA, LepA also known as Elongation Factor 4 (EF4). LepA
(also known as elongation factor 4, EF4) belongs to the
GTPase family and exhibits significant homology to the
translation factors EF-G and EF-Tu, indicating its
possible involvement in translation and association with
the ribosome. LepA is ubiquitous in bacteria and
eukaryota (e.g. yeast GUF1p), but is missing from
archaea. This pattern of phyletic distribution suggests
that LepA evolved through a duplication of the EF-G gene
in bacteria, followed by early transfer into the
eukaryotic lineage, most likely from the
promitochondrial endosymbiont. Yeast GUF1p is not
essential and mutant cells did not reveal any marked
phenotype.
