>gnl|CDD|206639 cd00066, G-alpha, Alpha subunit of G proteins (guanine nucleotide
binding). The alpha subunit of G proteins contains the
guanine nucleotide binding site. The heterotrimeric
GNP-binding proteins are signal transducers that
communicate signals from many hormones,
neurotransmitters, chemokines, and autocrine and
paracrine factors. Extracellular signals are received by
receptors, which activate the G proteins, which in turn
route the signals to several distinct intracellular
signaling pathways. The alpha subunit of G proteins is a
weak GTPase. In the resting state, heterotrimeric G
proteins are associated at the cytosolic face of the
plasma membrane and the alpha subunit binds to GDP. Upon
activation by a receptor GDP is replaced with GTP, and
the G-alpha/GTP complex dissociates from the beta and
gamma subunits. This results in activation of downstream
signaling pathways, such as cAMP synthesis by adenylyl
cyclase, which is terminated when GTP is hydrolized and
the heterotrimers reconstitute.

GTPases. Arf (ADP-ribosylation factor)/Arl (Arf-like)
small GTPases. Arf proteins are activators of
phospholipase D isoforms. Unlike Ras proteins they lack
cysteine residues at their C-termini and therefore are
unlikely to be prenylated. Arfs are N-terminally
myristoylated. Members of the Arf family are regulators
of vesicle formation in intracellular traffic that
interact reversibly with membranes of the secretory and
endocytic compartments in a GTP-dependent manner. They
depart from other small GTP-binding proteins by a unique
structural device, interswitch toggle, that implements
front-back communication from N-terminus to the
nucleotide binding site. Arf-like (Arl) proteins are
close relatives of the Arf, but only Arl1 has been shown
to function in membrane traffic like the Arf proteins.
Arl2 has an unrelated function in the folding of native
tubulin, and Arl4 may function in the nucleus. Most
other Arf family proteins are so far relatively poorly
characterized. Thus, despite their significant sequence
homologies, Arf family proteins may regulate unrelated
functions.

>gnl|CDD|206716 cd04149, Arf6, ADP ribosylation factor 6 (Arf6). Arf6 subfamily.
Arf6 (ADP ribosylation factor 6) proteins localize to
the plasma membrane, where they perform a wide variety
of functions. In its active, GTP-bound form, Arf6 is
involved in cell spreading, Rac-induced formation of
plasma membrane ruffles, cell migration, wound healing,
and Fc-mediated phagocytosis. Arf6 appears to change the
actin structure at the plasma membrane by activating
Rac, a Rho family protein involved in membrane ruffling.
Arf6 is required for and enhances Rac formation of
ruffles. Arf6 can regulate dendritic branching in
hippocampal neurons, and in yeast it localizes to the
growing bud, where it plays a role in polarized growth
and bud site selection. In leukocytes, Arf6 is required
for chemokine-stimulated migration across endothelial
cells. Arf6 also plays a role in down-regulation of
beta2-adrenergic receptors and luteinizing hormone
receptors by facilitating the release of sequestered
arrestin to allow endocytosis. Arf6 is believed to
function at multiple sites on the plasma membrane
through interaction with a specific set of GEFs, GAPs,
and effectors. Arf6 has been implicated in breast cancer
and melanoma cell invasion, and in actin remodelling at
the invasion site of Chlamydia infection.

>gnl|CDD|206717 cd04150, Arf1_5_like, ADP-ribosylation factor-1 (Arf1) and
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).

>gnl|CDD|133356 cd04156, ARLTS1, Arf-like tumor suppressor gene 1 (ARLTS1 or
Arl11). ARLTS1 (Arf-like tumor suppressor gene 1), also
known as Arl11, is a member of the Arf family of small
GTPases that is believed to play a major role in
apoptotic signaling. ARLTS1 is widely expressed and
functions as a tumor suppressor gene in several human
cancers. ARLTS1 is a low-penetrance suppressor that
accounts for a small percentage of familial melanoma or
familial chronic lymphocytic leukemia (CLL). ARLTS1
inactivation seems to occur most frequently through
biallelic down-regulation by hypermethylation of the
promoter. In breast cancer, ARLTS1 alterations were
typically a combination of a hypomorphic polymorphism
plus loss of heterozygosity. In a case of thyroid
adenoma, ARLTS1 alterations were polymorphism plus
promoter hypermethylation. The nonsense polymorphism
Trp149Stop occurs with significantly greater frequency
in familial cancer cases than in sporadic cancer cases,
and the Cys148Arg polymorphism is associated with an
increase in high-risk familial breast cancer.

>gnl|CDD|206723 cd04158, ARD1, (ADP-ribosylation factor domain protein 1 (ARD1).
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.

>gnl|CDD|206645 cd00879, Sar1, Sar1 is an essential component of COPII vesicle
coats. Sar1 is an essential component of COPII vesicle
coats involved in export of cargo from the ER. The
GTPase activity of Sar1 functions as a molecular switch
to control protein-protein and protein-lipid
interactions that direct vesicle budding from the ER.
Activation of the GDP to the GTP-bound form of Sar1
involves the membrane-associated guanine nucleotide
exchange factor (GEF) Sec12. Sar1 is unlike all Ras
superfamily GTPases that use either myristoyl or prenyl
groups to direct membrane association and function, in
that Sar1 lacks such modification. Instead, Sar1
contains a unique nine-amino-acid N-terminal extension.
This extension contains an evolutionarily conserved
cluster of bulky hydrophobic amino acids, referred to as
the Sar1-N-terminal activation recruitment (STAR) motif.
The STAR motif mediates the recruitment of Sar1 to ER
membranes and facilitates its interaction with mammalian
Sec12 GEF leading to activation.

>gnl|CDD|206718 cd04151, Arl1, ADP ribosylation factor 1 (Arf1). Arl1 subfamily.
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.

>gnl|CDD|206722 cd04157, Arl6, Arf-like 6 (Arl6) GTPase. Arl6 (Arf-like 6) forms a
subfamily of the Arf family of small GTPases. Arl6
expression is limited to the brain and kidney in adult
mice, but it is expressed in the neural plate and
somites during embryogenesis, suggesting a possible role
for Arl6 in early development. Arl6 is also believed to
have a role in cilia or flagella function. Several
proteins have been identified that bind Arl6, including
Arl6 interacting protein (Arl6ip), and SEC61beta, a
subunit of the heterotrimeric conducting channel SEC61p.
Based on Arl6 binding to these effectors, Arl6 is also
proposed to play a role in protein transport, membrane
trafficking, or cell signaling during hematopoietic
maturation. At least three specific homozygous Arl6
mutations in humans have been found to cause
Bardet-Biedl syndrome, a disorder characterized by
obesity, retinopathy, polydactyly, renal and cardiac
malformations, learning disabilities, and
hypogenitalism. Older literature suggests that Arl6 is a
part of the Arl4/Arl7 subfamily, but analyses based on
more recent sequence data place Arl6 in its own

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

>gnl|CDD|206720 cd04154, Arl2, Arf-like 2 (Arl2) GTPase. Arl2 (Arf-like 2) GTPases
are members of the Arf family that bind GDP and GTP with
very low affinity. Unlike most Arf family proteins, Arl2
is not myristoylated at its N-terminal helix. The
protein PDE-delta, first identified in photoreceptor rod
cells, binds specifically to Arl2 and is structurally
very similar to RhoGDI. Despite the high structural
similarity between Arl2 and Rho proteins and between
PDE-delta and RhoGDI, the interactions between the
GTPases and their effectors are very different. In its
GTP bound form, Arl2 interacts with the protein Binder
of Arl2 (BART), and the complex is believed to play a
role in mitochondrial adenine nucleotide transport. In
its GDP bound form, Arl2 interacts with tubulin- folding
Cofactor D; this interaction is believed to play a role
in regulation of microtubule dynamics that impact the
cytoskeleton, cell division, and cytokinesis.

>gnl|CDD|206725 cd04160, Arfrp1, Arf-related protein 1 (Arfrp1). Arfrp1
(Arf-related protein 1), formerly known as ARP, is a
membrane-associated Arf family member that lacks the
N-terminal myristoylation motif. Arfrp1 is mainly
associated with the trans-Golgi compartment and the
trans-Golgi network, where it regulates the targeting 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.

Arf family protein that differs from most Arf family
members in the N-terminal extension. In is inactive,
GDP-bound form, the N-terminal extension forms an
elongated loop that is hydrophobically anchored into the
membrane surface; however, it has been proposed that
this region might form a helix in the GTP-bound form.
The delta subunit of the rod-specific cyclic GMP
phosphodiesterase type 6 (PDEdelta) is an Arl3 effector.
Arl3 binds microtubules in a regulated manner to alter
specific aspects of cytokinesis via interactions with
retinitis pigmentosa 2 (RP2). It has been proposed that
RP2 functions in concert with Arl3 to link the cell
membrane and the cytoskeleton in photoreceptors as part
of the cell signaling or vesicular transport machinery.
In mice, the absence of Arl3 is associated with abnormal
epithelial cell proliferation and cyst formation.

fusion. Arl5 may also play a role in embryonic nuclear

GTPase superfamily. The Ras-like superfamily of small
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
translation factors, Era-like GTPases, and G-alpha chain
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.
