>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|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|206654 cd01861, Rab6, Rab GTPase family 6 (Rab6). Rab6 is involved in
microtubule-dependent transport pathways through the
Golgi and from endosomes to the Golgi. Rab6A of mammals
is implicated in retrograde transport through the Golgi
stack, and is also required for a slow,
COPI-independent, retrograde transport pathway from the
Golgi to the endoplasmic reticulum (ER). This pathway
may allow Golgi residents to be recycled through the ER
for scrutiny by ER quality-control systems. Yeast
Ypt6p, the homolog of the mammalian Rab6 GTPase, is not
essential for cell viability. Ypt6p acts in
endosome-to-Golgi, in intra-Golgi retrograde transport,
and possibly also in Golgi-to-ER trafficking. GTPase
activating proteins (GAPs) interact with GTP-bound Rab
and accelerate the hydrolysis of GTP to GDP. Guanine

Rab22; regulates early endosome fusion. The
Rab5-related subfamily includes Rab5 and Rab22 of
mammals, Ypt51/Ypt52/Ypt53 of yeast, and RabF of plants.
The members of this subfamily are involved in
endocytosis and endocytic-sorting pathways. In mammals,
Rab5 GTPases localize to early endosomes and regulate
fusion of clathrin-coated vesicles to early endosomes
and fusion between early endosomes. In yeast, Ypt51p
family members similarly regulate membrane trafficking
through prevacuolar compartments. GTPase activating

endosomes, together with mannose 6-phosphate receptors
(MPRs) and the tail-interacting protein of 47 kD
(TIP47). Rab9 is a key mediator of vesicular transport
from late endosomes to the trans-Golgi network (TGN) by
redirecting the MPRs. Rab9 has been identified as a key
component for the replication of several viruses,
including HIV1, Ebola, Marburg, and measles, making it

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

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

from other Rabs in several ways. It exists primarily in
the GTP-bound state, having a low intrinsic GTPase
activity; it is not efficiently geranyl-geranylated at
the C-terminus; it does not form a detectable complex
with Rab GDP-dissociation inhibitors (GDIs); and it has

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

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
diabetes therapy. When bound to JFC1 in prostate cells,
Rab27a is believed to regulate the exocytosis of
prostate- specific markers. GTPase activating proteins

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

several Rab proteins that appear to be restricted in
expression to the apical domain of murine polarized

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

nucleotide dissociation inhibitors (GDIs), which
facilitate Rab recycling by masking C-terminal lipid
binding and promoting cytosolic localization. Most Rab

(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

GTPase cdc42 and its GEF, cdc24, then establish an axis
of polarized growth by organizing the actin cytoskeleton

hypha and at novel growth sites along the extending
hypha. In Ashbya gossypii, RSR1 is a key regulator of

regulating in apical polarization of the actin
cytoskeleton. Most Ras proteins contain a lipid

nucleotide dissociation inhibitors (GDIs), which
facilitate Rab recycling by masking C-terminal lipid
binding and promoting cytosolic localization. Most Rab

Rap2c. The Rap2 subgroup is part of the Rap subfamily
of the Ras family. It consists of Rap2a, Rap2b, and
Rap2c. Both isoform 3 of the human mitogen-activated
protein kinase kinase kinase kinase 4 (MAP4K4) and
Traf2- and Nck-interacting kinase (TNIK) are putative
effectors of Rap2 in mediating the activation of c-Jun
N-terminal kinase (JNK) to regulate the actin
cytoskeleton. In human platelets, Rap2 was shown to
interact with the cytoskeleton by binding the actin
filaments. In embryonic Xenopus development, Rap2 is
necessary for the Wnt/beta-catenin signaling pathway.
The Rap2 interacting protein 9 (RPIP9) is highly
expressed in human breast carcinomas and correlates
with a poor prognosis, suggesting a role for Rap2 in
breast cancer oncogenesis. Rap2b, but not Rap2a, Rap2c,
Rap1a, or Rap1b, is expressed in human red blood cells,
where it is believed to be involved in vesiculation. A
number of additional effector proteins for Rap2 have
been identified, including the RalGEFs RalGDS, RGL, and
Rlf, which also interact with Rap1 and Ras. 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

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

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

While Rac1 is ubiquitously expressed, Rac2 and Rac3 are

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.

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

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

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.

This subfamily includes Rhes (Ras homolog enriched in
striatum) and Dexras1/AGS1 (activator of G-protein
signaling 1). These proteins are homologous, but
exhibit significant differences in tissue distribution
and subcellular localization. Rhes is found primarily
in the striatum of the brain, but is also expressed in
other areas of the brain, such as the cerebral cortex,
hippocampus, inferior colliculus, and cerebellum. Rhes
expression is controlled by thyroid hormones. In rat
PC12 cells, Rhes is farnesylated and localizes to the
plasma membrane. Rhes binds and activates PI3K, and
plays a role in coupling serpentine membrane receptors
with heterotrimeric G-protein signaling. Rhes has
recently been shown to be reduced under conditions of
dopamine supersensitivity and may play a role in
determining dopamine receptor sensitivity. Dexras1/AGS1
is a dexamethasone-induced Ras protein that is
expressed primarily in the brain, with low expression
levels in other tissues. Dexras1 localizes primarily to
the cytoplasm, and is a critical regulator of the
circadian master clock to photic and nonphotic input.

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

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

(Rab-like2) subfamily. RabL2s are novel Rab proteins
identified recently which display features that are
distinct from other Rabs, and have been termed
Rab-like. RabL2 contains RabL2a and RabL2b, two very
similar Rab proteins that share > 98% sequence identity
in humans. RabL2b maps to the subtelomeric region of
chromosome 22q13.3 and RabL2a maps to 2q13, a region
that suggests it is also a subtelomeric gene. Both
genes are believed to be expressed ubiquitously,
suggesting that RabL2s are the first example of
duplicated genes in human proximal subtelomeric regions
that are both expressed actively. Like other Rab-like
proteins, RabL2s lack a prenylation site at the
C-terminus. The specific functions of RabL2a and RabL2b
remain unknown. 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.

Rab40b and Rab40c. The Rab40 subfamily contains
Rab40a, Rab40b, and Rab40c, which are all highly
homologous. In rat, Rab40c is localized to the
perinuclear recycling compartment (PRC), and is
distributed in a tissue-specific manor, with high
expression in brain, heart, kidney, and testis, low
expression in lung and liver, and no expression in
spleen and skeletal muscle. Rab40c is highly expressed
in differentiated oligodendrocytes but minimally
expressed in oligodendrocyte progenitors, suggesting a
role in the vesicular transport of myelin components.
Unlike most other Ras-superfamily proteins, Rab40c was
shown to have a much lower affinity for GTP, and an
affinity for GDP that is lower than for GTP. GTPase
activating proteins (GAPs) interact with GTP-bound Rab
and accelerate the hydrolysis of GTP to GDP. Guanine

>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

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

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.

gamma 1 is also called PIKE (phosphatidyl inositol (PI)
3-kinase enhancer) and centaurin gamma 2 is also known
as AGAP (ArfGAP protein with a GTPase-like domain,

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

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

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

with GTP hydrolysis to promote the tRNA modification
reaction, in which the conserved cysteine in the
C-terminal domain is thought to function as a catalytic
residue. In bacteria that are able to survive in
extremely low pH conditions, TrmE regulates
glutamate-dependent acid resistance.

GTPase. Era (E. coli Ras-like protein) is a
multifunctional GTPase found in all bacteria except
some eubacteria. It binds to the 16S ribosomal RNA
(rRNA) of the 30S subunit and appears to play a role in
the assembly of the 30S subunit, possibly by
chaperoning the 16S rRNA. It also contacts several
assembly elements of the 30S subunit. Era couples cell
growth with cytokinesis and plays a role in cell
division and energy metabolism. Homologs have also been
found in eukaryotes. Era contains two domains: the
N-terminal GTPase domain and a C-terminal domain KH
domain that is critical for RNA binding. Both domains
are important for Era function. Era is functionally
able to compensate for deletion of RbfA, a cold-shock
adaptation protein that is required for efficient
processing of the 16S rRNA.

>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.

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

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

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,

Dynamin-like C-terminal Eps15 homology domain (EHD)
proteins regulate endocytic events; they have been
linked to a number of Rab proteins through their
association with mutual effectors, suggesting a
coordinate role in endocytic regulation. Eukaryotic
EHDs comprise four members (EHD1-4) in mammals and
single members in Caenorhabditis elegans (Rme-1),
Drosophila melanogaster (Past1) as well as several
eukaryotic parasites. EHD1 regulates trafficking of
multiple receptors from the endocytic recycling
compartment (ERC) to the plasma membrane; EHD2
regulates trafficking from the plasma membrane by
controlling Rac1 activity; EHD3 regulates
endosome-to-Golgi transport, and preserves Golgi
morphology; EHD4 is involved in the control of
trafficking at the early endosome and regulates exit of
cargo toward the recycling compartment as well as late
endocytic pathway. Rme-1, an ortholog of human EHD1,
controls the recycling of internalized receptors from
the endocytic recycling compartment to the plasma
membrane. In D. melanogaster, deletion of the Past1
gene leads to infertility as well as premature death of
adult flies. Arabidopsis thaliana also has homologs of
EHD proteins (AtEHD1 and AtEHD2), possibly involved in
regulating endocytosis and signaling.

Mx proteins. The dynamin family of large
mechanochemical GTPases includes the classical dynamins
and dynamin-like proteins (DLPs) that are found
throughout the Eukarya. 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 interferon-induced Mx proteins that inhibit a
wide range of viruses by blocking an early stage of the
replication cycle. Dynamin oligomerizes into helical
structures around the neck of budding vesicles in a GTP
hydrolysis-dependent manner.
