>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|206694 cd04109, Rab28, Rab GTPase family 28 (Rab28). Rab28 subfamily.
First identified in maize, Rab28 has been shown to be a
late embryogenesis-abundant (Lea) protein that is
regulated by the plant hormone abcisic acid (ABA). In
Arabidopsis, Rab28 is expressed during embryo
development and is generally restricted to provascular
tissues in mature embryos. Unlike maize Rab28, it is not
ABA-inducible. Characterization of the human Rab28
homolog revealed two isoforms, which differ by a 95-base
pair insertion, producing an alternative sequence for
the 30 amino acids at the C-terminus. The two human
isoforms are presumably the result of alternative
splicing. Since they differ at the C-terminus but not in
the GTP-binding region, they are predicted to be
targeted to different cellular locations. GTPase
activating proteins (GAPs) interact with GTP-bound Rab
and accelerate the hydrolysis of GTP to GDP. Guanine
nucleotide exchange factors (GEFs) interact with
GDP-bound Rabs to promote the formation of the GTP-bound
state. Rabs are further regulated by guanine nucleotide
dissociation inhibitors (GDIs), which facilitate Rab
recycling by masking C-terminal lipid binding and
promoting cytosolic localization. Most Rab GTPases
contain a lipid modification site at the C-terminus,
with sequence motifs CC, CXC, or CCX. Lipid binding is
essential for membrane attachment, a key feature of most
Rab proteins.

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

>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

>gnl|CDD|206659 cd01867, Rab8_Rab10_Rab13_like, Rab GTPase families 8, 10, 13
(Rab8, Rab10, Rab13). Rab8/Sec4/Ypt2 are known or
suspected to be involved in post-Golgi transport to the
plasma membrane. It is likely that these Rabs have
functions that are specific to the mammalian lineage and
have no orthologs in plants. Rab8 modulates polarized
membrane transport through reorganization of actin and
microtubules, induces the formation of new surface
extensions, and has an important role in directed
membrane transport to cell surfaces. The Ypt2 gene of
the fission yeast Schizosaccharomyces pombe encodes a
member of the Ypt/Rab family of small GTP-binding
proteins, related in sequence to Sec4p of Saccharomyces
cerevisiae but closer to mammalian Rab8. GTPase
activating proteins (GAPs) interact with GTP-bound Rab
and accelerate the hydrolysis of GTP to GDP. Guanine

>gnl|CDD|206657 cd01865, Rab3, Rab GTPase family 3 contains Rab3A, Rab3B, Rab3C and
Rab3D. The Rab3 subfamily contains Rab3A, Rab3B, Rab3C,
and Rab3D. All four isoforms were found in mouse brain
and endocrine tissues, with varying levels of
expression. Rab3A, Rab3B, and Rab3C localized to
synaptic and secretory vesicles; Rab3D was expressed at
high levels only in adipose tissue, exocrine glands, and
the endocrine pituitary, where it is localized to
cytoplasmic secretory granules. Rab3 appears to control
Ca2+-regulated exocytosis. The appropriate GDP/GTP
exchange cycle of Rab3A is required for Ca2+-regulated
exocytosis to occur, and interaction of the GTP-bound
form of Rab3A with effector molecule(s) is widely
believed to be essential for this process. Functionally,
most studies point toward a role for Rab3 in the
secretion of hormones and neurotransmitters. GTPase
activating proteins (GAPs) interact with GTP-bound Rab
and accelerate the hydrolysis of GTP to GDP. Guanine
nucleotide exchange factors (GEFs) interact with

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

>gnl|CDD|206700 cd04127, Rab27A, Rab GTPase family 27a (Rab27a). The Rab27a
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
(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

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,
the lipid modification site is not available for

several Rab proteins to be found to participate in the
regulation of osteoclast cells in rats. In addition,
Rab35 has been identified as a protein that interacts
with nucleophosmin-anaplastic lymphoma kinase (NPM-ALK)
in human cells. Overexpression of NPM-ALK is a key
oncogenic event in some anaplastic large-cell lymphomas;
since Rab35 interacts with N|PM-ALK, it may provide a
target for cancer treatments. 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.

GTPases consists of several families with an extremely
high degree of structural and functional similarity. The
Ras superfamily is divided into at least four families
in eukaryotes: the Ras, Rho, Rab, and Sar1/Arf families.
This superfamily also includes proteins like the GTP

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

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

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

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,

proteins are believed to play a crucial role in

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

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.

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

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

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.

>gnl|CDD|217025 pfam02421, FeoB_N, Ferrous iron transport protein B. Escherichia
coli has an iron(II) transport system (feo) which may
make an important contribution to the iron supply of
the cell under anaerobic conditions. FeoB has been
identified as part of this transport system. FeoB is a
large 700-800 amino acid integral membrane protein. The
N terminus contains a P-loop motif suggesting that iron
transport may be ATP dependent.

>gnl|CDD|206692 cd04107, Rab32_Rab38, Rab GTPase families 18 (Rab18) and 32
(Rab32). Rab38/Rab32 subfamily. Rab32 and Rab38 are
members of the Rab family of small GTPases. Human Rab32
was first identified in platelets but it is expressed in
a variety of cell types, where it functions as an
A-kinase anchoring protein (AKAP). Rab38 has been shown
to be melanocyte-specific. GTPase activating proteins
(GAPs) interact with GTP-bound Rab and accelerate the
hydrolysis of GTP to GDP. Guanine nucleotide exchange
factors (GEFs) interact with GDP-bound Rabs to promote
the formation of the GTP-bound state. Rabs are further
regulated by guanine nucleotide dissociation inhibitors
(GDIs), which facilitate Rab recycling by masking
C-terminal lipid binding and promoting cytosolic
localization. Most Rab GTPases contain a lipid
modification site at the C-terminus, with sequence
motifs CC, CXC, or CCX. Lipid binding is essential for
membrane attachment, a key feature of most Rab proteins.

>gnl|CDD|206726 cd04163, Era, E. coli Ras-like protein (Era) is a multifunctional
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.
