1, 2, and 3 pleckstrin homology (PH) domain. PEPP1
(also called PLEKHA4/PH domain-containing family A
member 4 and RHOXF1/Rhox homeobox family member 1), and
related homologs PEPP2 (also called PLEKHA5/PH
domain-containing family A member 5) and PEPP3 (also
called PLEKHA6/PH domain-containing family A member 6),
have PH domains that interact specifically with
PtdIns(3,4)P3. Other proteins that bind PtdIns(3,4)P3
specifically are: TAPP1 (tandem PH-domain-containing
protein-1) and TAPP2], PtdIns3P AtPH1, and Ptd-
Ins(3,5)P2 (centaurin-beta2). All of these proteins
contain at least 5 of the 6 conserved amino acids that
make up the putative phosphatidylinositol 3,4,5-
trisphosphate-binding motif (PPBM) located at their
N-terminus. PH domains have diverse functions, but in
general are involved in targeting proteins to the
appropriate cellular location or in the interaction with
a binding partner. They share little sequence
conservation, but all have a common fold, which is
electrostatically polarized. Less than 10% of PH domains
bind phosphoinositide phosphates (PIPs) with high
affinity and specificity. PH domains are distinguished
from other PIP-binding domains by their specific
high-affinity binding to PIPs with two vicinal phosphate
groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3
which results in targeting some PH domain proteins to
the plasma membrane. A few display strong specificity in
lipid binding. Any specificity is usually determined by
loop regions or insertions in the N-terminus of the
domain, which are not conserved across all PH domains.
PH domains are found in cellular signaling proteins such
as serine/threonine kinase, tyrosine kinases, regulators
of G-proteins, endocytotic GTPases, adaptors, as well as
cytoskeletal associated molecules and in lipid
associated enzymes.

in eukaryotic signalling proteins. The domain family
possesses multiple functions including the abilities to
bind inositol phosphates, and various proteins. PH
domains have been found to possess inserted domains
(such as in PLC gamma, syntrophins) and to be inserted
within other domains. Mutations in Brutons tyrosine
kinase (Btk) within its PH domain cause X-linked
agammaglobulinaemia (XLA) in patients. Point mutations
cluster into the positively charged end of the molecule
around the predicted binding site for

suppressor of ras) (CNK) pleckstrin homology (PH)
domain. CNK family members function as protein
scaffolds, regulating the activity and the subcellular
localization of RAS activated RAF. There is a single CNK
protein present in Drosophila and Caenorhabditis elegans
in contrast to mammals which have 3 CNK proteins (CNK1,
CNK2, and CNK3). All of the CNK members contain a
sterile a motif (SAM), a conserved region in CNK (CRIC)
domain, and a PSD-95/DLG-1/ZO-1 (PDZ) domain, and, with
the exception of CNK3, a PH domain. A CNK2 splice
variant CNK2A also has a PDZ domain-binding motif at its
C terminus and Drosophila CNK (D-CNK) also has a domain
known as the Raf-interacting region (RIR) that mediates
binding of the Drosophila Raf kinase. This cd contains
CNKs from mammals, chickens, amphibians, fish, and
crustacea. PH domains have diverse functions, but in

>gnl|CDD|241390 cd13236, PH2_FGD1-4, FYVE, RhoGEF and PH domain
containing/faciogenital dysplasia proteins pleckstrin
homology (PH) domain, C-terminus. In general, FGDs have
a RhoGEF (DH) domain, followed by an N-terminal PH
domain, a FYVE domain and a C-terminal PH domain. All
FGDs are guanine nucleotide exchange factors that
activates the Rho GTPase Cdc42, an important regulator
of membrane trafficking. The RhoGEF domain is
responsible for GEF catalytic activity, while the
N-terminal PH domain is involved in intracellular
targeting of the DH domain. Not much is known about
FGD2. FGD1 is the best characterized member of the
group with mutations here leading to the X-linked
disorder known as faciogenital dysplasia (FGDY). Both
FGD1 and FGD3 are targeted by the ubiquitin ligase
SCF(FWD1/beta-TrCP) upon phosphorylation of two serine
residues in its DSGIDS motif and subsequently degraded
by the proteasome. However, FGD1 and FGD3 induced
significantly different morphological changes in HeLa
Tet-Off cells and while FGD1 induced long finger-like
protrusions, FGD3 induced broad sheet-like protrusions
when the level of GTP-bound Cdc42 was significantly
increased by the inducible expression of FGD3. They also
reciprocally regulated cell motility in inducibly
expressed in HeLa Tet-Off cells, FGD1 stimulated cell
migration while FGD3 inhibited it. FGD1 and FGD3
therefore play different roles to regulate cellular
functions, even though their intracellular levels are
tightly controlled by the same destruction pathway
through SCF(FWD1/beta-TrCP). FGD4 is one of the genes
associated with Charcot-Marie-Tooth neuropathy type 4
(CMT4), a group of progressive motor and sensory axonal
and demyelinating neuropathies that are distinguished
from other forms of CMT by autosomal recessive
inheritance. Those affected have distal muscle weakness
and atrophy associated with sensory loss and,
frequently, pes cavus foot deformity. PH domains have
diverse functions, but in general are involved in
targeting proteins to the appropriate cellular location
or in the interaction with a binding partner. They share
little sequence conservation, but all have a common
fold, which is electrostatically polarized. Less than
10% of PH domains bind phosphoinositide phosphates
(PIPs) with high affinity and specificity. PH domains
are distinguished from other PIP-binding domains by

>gnl|CDD|241470 cd13316, PH_Boi, Boi family Pleckstrin homology domain. Yeast Boi
proteins Boi1 and Boi2 are functionally redundant and
important for cell growth with Boi mutants displaying
defects in bud formation and in the maintenance of cell
polarity.They appear to be linked to Rho-type GTPase,
Cdc42 and Rho3. Boi1 and Boi2 display two-hybrid
interactions with the GTP-bound ("active") form of
Cdc42, while Rho3 can suppress of the lethality caused
by deletion of Boi1 and Boi2. These findings suggest
that Boi1 and Boi2 are targets of Cdc42 that promote
cell growth in a manner that is regulated by Rho3. Boi
proteins contain a N-terminal SH3 domain, followed by a
SAM (sterile alpha motif) domain, a proline-rich region,
which mediates binding to the second SH3 domain of Bem1,
and C-terminal PH domain. The PH domain is essential for
its function in cell growth and is important for
localization to the bud, while the SH3 domain is needed
for localization to the neck. PH domains have diverse
functions, but in general are involved in targeting
proteins to the appropriate cellular location or in the

members: Ses1 and Ses2, which are also callled 7 kDa
inositol polyphosphate phosphatase-interacting protein 1
and 2. They play a role in endocytic trafficking and are
required for receptor recycling from endosomes, both to
the trans-Golgi network and the plasma membrane. Members

(PH) domain. SH3BP2 (the gene that encodes the adaptor
protein 3BP2), HD, ITU, IT10C3, and ADD1 are located
near the Huntington's Disease Gene on Human Chromosome
4pl6.3. SH3BP2 lies in a region that is often missing in
individuals with Wolf-Hirschhorn syndrome (WHS). Gain of
function mutations in SH3BP2 causes enhanced B-cell
antigen receptor (BCR)-mediated activation of nuclear
factor of activated T cells (NFAT), resulting in a rare,
genetic disorder called cherubism. This results in an
increase in the signaling complex formation with Syk,
phospholipase C-gamma2 (PLC-gamma2), and Vav1. It was
recently discovered that Tankyrase regulates 3BP2
stability through ADP-ribosylation and ubiquitylation by
the E3-ubiquitin ligase. Cherubism mutations uncouple
3BP2 from Tankyrase-mediated protein destruction, which
results in its stabilization and subsequent
hyperactivation of the Src, Syk, and Vav signaling
pathways. SH3BP2 is also a potential negative regulator
of the abl oncogene. PH domains have diverse functions,

N-terminal DUF3398 domain, a PH-like domain, a Dock
Homology Region 1, DHR1 (also called CZH1), a C2 domain,
and a C-terminal DHR2 domain (also called CZH2).
Zizimin1 is enriched in the brain, lung, and kidney;
zizimin2 is found in B and T lymphocytes, and zizimin3
is enriched in brain, lung, spleen and thymus. Zizimin1
functions in autoinhibition and membrane targeting.
Zizimin2 is an immune-related and age-regulated guanine
nucleotide exchange factor, which facilitates filopodial
formation through activation of Cdc42, which results in
activation of cell migration. No function has been
determined for Zizimin3 to date. The N-terminal half of
zizimin1 binds to the GEF domain through three distinct
areas, including CZH1, to inhibit the interaction with
Cdc42. In addition its PH domain binds phosphoinositides
and mediates zizimin1 membrane targeting. DOCK is a
family of proteins involved in intracellular signalling
networks. They act as guanine nucleotide exchange
factors for small G proteins of the Rho family, such as
Rac and Cdc42. There are 4 subfamilies of DOCK family
proteins based on their sequence homology: A-D. PH
domains have diverse functions, but in general are
involved in targeting proteins to the appropriate
cellular location or in the interaction with a binding
partner. They share little sequence conservation, but
all have a common fold, which is electrostatically
polarized. Less than 10% of PH domains bind
phosphoinositide phosphates (PIPs) with high affinity
and specificity. PH domains are distinguished from other
PIP-binding domains by their specific high-affinity
binding to PIPs with two vicinal phosphate groups:
PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which
results in targeting some PH domain proteins to the
plasma membrane. A few display strong specificity in
lipid binding. Any specificity is usually determined by
loop regions or insertions in the N-terminus of the
domain, which are not conserved across all PH domains.
PH domains are found in cellular signaling proteins such
as serine/threonine kinase, tyrosine kinases, regulators
of G-proteins, endocytotic GTPases, adaptors, as well as
cytoskeletal associated molecules and in lipid
associated enzymes.

of GTPase-activating proteins. RASA1 contains N-terminal
SH2-SH3-SH2 domains, followed by two C2 domains, a PH
domain, a RasGAP domain, and a BTK domain. Splice
variants lack the N-terminal domains. It is a cytosolic
vertebrate protein that acts as a suppressor of RAS via
its C-terminal GAP domain function, enhancing the weak
intrinsic GTPase activity of RAS proteins resulting in
the inactive GDP-bound form of RAS, allowing control of
cellular proliferation and differentiation.
Additionally, it is involved in mitogenic signal
transmission towards downstream interacting partners
through its N-terminal SH2-SH3-SH2 domains. RASA1
interacts with a number of proteins including: G3BP1,
SOCS3, ANXA6, Huntingtin, KHDRBS1, Src, EPHB3, EPH

is activated by receptor and non-receptor tyrosine

There are two main isoforms of PLC-gamma expressed in
human specimens, PLC-gamma1 and PLC-gamma2. PLC-gamma
consists of an N-terminal PH domain, a EF hand domain,
a catalytic domain split into X and Y halves internal
to which is a PH domain split by two SH2 domains and a
single SH3 domain, and a C-terminal C2 domain. The
split PH domain is present in this hierarchy. PLCs (EC
3.1.4.3) play a role in the initiation of cellular
activation, proliferation, differentiation and
apoptosis. They are central to inositol lipid
signalling pathways, facilitating intracellular Ca2+
release and protein kinase C (PKC) activation.
Specificaly, PLCs catalyze the cleavage of
phosphatidylinositol-4,5-bisphosphate (PIP2) and result
in the release of 1,2-diacylglycerol (DAG) and inositol
1,4,5-triphosphate (IP3). These products trigger the
activation of protein kinase C (PKC) and the release of
Ca2+ from intracellular stores. There are fourteen

are classified into six isotypes (beta, gamma, delta,
epsilon, zeta, eta). PH domains have diverse functions,

GRF2; Ras guanine nucleotide exchange factor 2) are a
family of guanine nucleotide exchange factors (GEFs).
They both promote the exchange of Ras-bound GDP by GTP,
thereby regulating the RAS signaling pathway. RasGRF1
and RasGRF2 form homooligomers and heterooligomers. GRF1
has 3 isoforms and GRF2 has 2 isoforms. The longest
isoforms of RasGRF1 and RasGRF2 contain the following
domains: a Rho-GEF domain sandwiched between 2 PH
domains, IQ domains, a REM (Ras exchanger motif) domain,
and a Ras-GEF domainwhich gives them the capacity to
activate both Ras and Rac GTPases in response to signals
from a variety of neurotransmitter receptors. Their IQ
domains allow them to act as calcium sensors to mediate
the actions of NMDA-type and calcium-permeable AMPA-type
glutamate receptors. GRF1 also mediates the action of
dopamine receptors that signal through cAMP. GRF1 and

>gnl|CDD|241307 cd10571, PH_beta_spectrin, Beta-spectrin pleckstrin homology (PH)
domain. Beta spectrin binds actin and functions as a
major component of the cytoskeleton underlying cellular
membranes. Beta spectrin consists of multiple spectrin
repeats followed by a PH domain, which binds to
inositol-1,4,5-trisphosphate. The PH domain of
beta-spectrin is thought to play a role in the
association of spectrin with the plasma membrane of
cells. PH domains have diverse functions, but in general
are involved in targeting proteins to the appropriate
cellular location or in the interaction with a binding
partner. They share little sequence conservation, but
all have a common fold, which is electrostatically
polarized. Less than 10% of PH domains bind
phosphoinositide phosphates (PIPs) with high affinity
and specificity. PH domains are distinguished from other
PIP-binding domains by their specific high-affinity
binding to PIPs with two vicinal phosphate groups:
PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which
results in targeting some PH domain proteins to the
plasma membrane. A few display strong specificity in
lipid binding. Any specificity is usually determined by
loop regions or insertions in the N-terminus of the
domain, which are not conserved across all PH domains.
PH domains are found in cellular signaling proteins such
as serine/threonine kinase, tyrosine kinases, regulators
of G-proteins, endocytotic GTPases, adaptors, as well as
cytoskeletal associated molecules and in lipid
associated enzymes.

FGD6 is unknown. In general, FGDs have a RhoGEF (DH)
domain, followed by a PH domain, a FYVE domain and a
C-terminal PH domain. All FGDs are guanine nucleotide
exchange factors that activate the Rho GTPase Cdc42, an
important regulator of membrane trafficking. The RhoGEF

the PH domain is involved in intracellular targeting of
the DH domain. PH domains have diverse functions, but

anillin-like yeast protein involved in the formation and
the disassembly of the double ring structure formed by
the septins during cytokinesis. Bud4 acts with Bud3 and
and in parallel with septin phosphorylation by the
p21-activated kinase Cla4 and the septin-dependent
kinase Gin4. Bud4 is regulated by the cyclin-dependent
protein kinase Cdk1, the master regulator of cell cycle
progression. Bud4 contains an anillin-like domain
followed by a PH domain. In addition there are two
consensus Cdk phosphorylation sites: one at the
N-terminus and one right before the C-terminal PH
domain. Anillins also have C-terminal PH domains. PH

homology (PH) domain. The Gab subfamily includes
several Gab proteins, Drosophila DOS and C. elegans
SOC-1. They are scaffolding adaptor proteins, which
possess N-terminal PH domains and a C-terminus with
proline-rich regions and multiple phosphorylation sites.
Following activation of growth factor receptors, Gab
proteins are tyrosine phosphorylated and activate PI3K,
which generates 3-phosphoinositide lipids. By binding to
these lipids via the PH domain, Gab proteins remain in
proximity to the receptor, leading to further signaling.
While not all Gab proteins depend on the PH domain for
recruitment, it is required for Gab activity. The
members in this cd include the Gab1, Gab2, and Gab3
proteins. PH domains have diverse functions, but in
general are involved in targeting proteins to the
appropriate cellular location or in the interaction with
a binding partner. They share little sequence

contain a N-terminal PH domain and a C-terminal
OSBP-related domain. Not much is known about its
specific function in plants to date. Members here
include: Arabidopsis, spruce, and petunia. Oxysterol
binding proteins are a multigene family that is
conserved in yeast, flies, worms, mammals and plants. In
general OSBPs and ORPs have been found to be involved in
the transport and metabolism of cholesterol and related
lipids in eukaryotes. They all contain a C-terminal
oxysterol binding domain, and most contain an N-terminal
PH domain. OSBP PH domains bind to membrane
phosphoinositides and thus likely play an important role
in intracellular targeting. They are members of the
oxysterol binding protein (OSBP) family which includes
OSBP, OSBP-related proteins (ORP), Goodpasture antigen
binding protein (GPBP), and Four phosphate adaptor
protein 1 (FAPP1). They have a wide range of purported
functions including sterol transport, cell cycle
control, pollen development and vessicle transport from
