>gnl|CDD|133267 cd01864, Rab19, Rab GTPase family 19 (Rab19). Rab19 subfamily.
Rab19 proteins are associated with Golgi stacks.
Similarity analysis indicated that Rab41 is closely
related to Rab19. However, the function of these Rabs
is not yet characterized. 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.

(Rab8, Rab10, Rab13). Rab8/Sec4/Ypt2 are known or
suspected to be involved in post-Golgi transport to the
plasma membrane. It is likely that these Rabs have
functions that are specific to the mammalian lineage
and have no orthologs in plants. Rab8 modulates
polarized membrane transport through reorganization of
actin and microtubules, induces the formation of new
surface extensions, and has an important role in
directed membrane transport to cell surfaces. The Ypt2
gene of the fission yeast Schizosaccharomyces pombe
encodes a member of the Ypt/Rab family of small
GTP-binding proteins, related in sequence to Sec4p of
Saccharomyces cerevisiae but closer to mammalian Rab8.

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

ubiquitously expressed in mouse tissues and cells,
where it is localized to the medial Golgi cisternae. It
colocalizes with alpha-mannose II. Together with the
other cisternal Rabs, Rab6A and Rab6A', it is believed
to regulate the Golgi response to stress and is likely
a molecular target in stress-activated signaling
pathways. Rab33A (previously known as S10) is expressed
primarily in the brain and immune system cells. In
humans, it is located on the X chromosome at Xq26 and
its expression is down-regulated in tuberculosis

functions. Rab27a has multiple effector proteins, and
depending on which effector it binds, Rab27a has
different functions as well as tissue distribution

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

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
a potential target for inhibiting a variety of viruses.
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.

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

RabL2 contains RabL2a and RabL2b, two very similar Rab

RabL2b maps to the subtelomeric region of chromosome
22q13.3 and RabL2a maps to 2q13, a region that suggests
it is also a subtelomeric gene. Both genes are believed
to be expressed ubiquitously, suggesting that RabL2s 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.

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

(septum-promoting GTPase) was first identified in the
fission yeast S. pombe, where it regulates septum
formation in the septation initiation network (SIN)
through the cdc7 protein kinase. Spg1p is an essential
gene that localizes to the spindle pole bodies. When
GTP-bound, it binds cdc7 and causes it to translocate
to spindle poles. Sid4p (septation initiation
defective) is required for localization of Spg1p to the
spindle pole body, and the ability of Spg1p to promote
septum formation from any point in the cell cycle
depends on Sid4p. Spg1p is negatively regulated by Byr4
and cdc16, which form a two-component GTPase activating
protein (GAP) for Spg1p. The existence of a SIN-related
pathway in plants has been proposed. GTPase activating
proteins (GAPs) interact with GTP-bound Rab and
accelerate the hydrolysis of GTP to GDP. Guanine

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

Instead, RhoG interacts directly with Elmo, an upstream

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

of growth direction. Rho2 activates the protein kinase C

regulates the construction of the cell wall. Unlike

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).

(Ras-like protein in all tissues), Rin (Ras-like

several unique structural and functional
characteristics. These proteins all lack a the
C-terminal CaaX lipid-binding motif typical of Ras

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.

subfamily. Rheb was initially identified in rat brain,
where its expression is elevated by seizures or by

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

TSC1/TSC2 complex inhibits the activation of TOR kinase
through Rheb. Rheb has also been shown to induce the

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

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

have a direct role in exocytosis that is independent of
its role in regulating actin polarity. The function in
exocytosis may be two-pronged: first, in the transport
of post-Golgi vesicles from the mother cell to the bud,
mediated by myosin (Myo2); second, in the docking and
fusion of vesicles to the plasma membrane, mediated by
an exocyst (Exo70) protein. Most Rho proteins contain a
lipid modification site at the C-terminus, with a
typical sequence motif CaaX, where a = an aliphatic
amino acid and X = any amino acid. Lipid binding is
essential for membrane attachment, a key feature of most
Rho proteins.

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

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

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

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

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.
Most Ras proteins contain a lipid modification site at

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.

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.

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

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

(Arf-related protein 1), formerly known as ARP, is a

associated with the trans-Golgi compartment and the

of Arl1 and the GRIP domain-containing proteins,
golgin-97 and golgin-245, onto Golgi membranes. It is
also involved in the anterograde transport of the
vesicular stomatitis virus G protein from the Golgi to
the plasma membrane, and in the retrograde transport of
TGN38 and Shiga toxin from endosomes to the trans-Golgi
network. Arfrp1 also inhibits Arf/Sec7-dependent
activation of phospholipase D. Deletion of Arfrp1 in
mice causes embryonic lethality at the gastrulation
stage and apoptosis of mesodermal cells, indicating its
importance in development.

GDP-bound form, the N-terminal extension forms an

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

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

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

2-methylcitrate cycle is one of at least five
degradation pathways for propionate via propionyl-CoA.
Degradation of propionate toward pyruvate consumes
oxaloacetate and releases succinate. Oxidation of
succinate back into oxaloacetate by the TCA cycle makes
the 2-methylcitrate pathway a cycle. This family
consists of PrpF, an incompletely characterized protein
that appears to be an essential accessory protein for
the Fe/S-dependent 2-methylisocitrate dehydratase AcnD
(TIGR02333). This protein is related to but distinct
from FldA (part of Pfam family pfam04303), a putative
fluorene degradation protein of Sphingomonas sp. LB126
[Energy metabolism, Fermentation].

bind GTP. As regards the septins, these are
polypeptides of 30-65kDa with three characteristic
GTPase motifs (G-1, G-3 and G-4) that are similar to
those of the Ras family. The G-4 motif is strictly
conserved with a unique septin consensus of AKAD. Most
septins are thought to have at least one coiled-coil
region, which in some cases is necessary for
intermolecular interactions that allow septins to
polymerise to form rod-shaped complexes. In turn, these
are arranged into tandem arrays to form filaments. They
are multifunctional proteins, with roles in

heterodimeric signal recognition particle (SRP).
Signal recognition particle receptor, beta subunit
(SR-beta). SR-beta and SR-alpha form the heterodimeric
signal recognition particle (SRP or SR) receptor that
binds SRP to regulate protein translocation across the
ER membrane. Nascent polypeptide chains are synthesized
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.

that the Dictyostelium RacA GTPase domain is more
