>gnl|CDD|212760 cd11826, SH3_Abi, Src homology 3 domain of Abl Interactor proteins.
Abl interactor (Abi) proteins are adaptor proteins
serving as binding partners and substrates of Abl
tyrosine kinases. They are involved in regulating actin
cytoskeletal reorganization and play important roles in
membrane-ruffling, endocytosis, cell motility, and cell
migration. They localize to sites of actin
polymerization in epithelial adherens junction and
immune synapses, as well as to the leading edge of
lamellipodia. Vertebrates contain two Abi proteins, Abi1
and Abi2. Abi1 displays a wide expression pattern while
Abi2 is highly expressed in the eye and brain. Abi
proteins contain a homeobox homology domain, a
proline-rich region, and a SH3 domain. The SH3 domain of
Abi binds to a PxxP motif in Abl. SH3 domains are
protein interaction domains that bind to proline-rich
ligands with moderate affinity and selectivity,
preferentially to PxxP motifs. They play versatile and
diverse roles in the cell including the regulation of
enzymes, changing the subcellular localization of
signaling pathway components, and mediating the
formation of multiprotein complex assemblies.

Abi1, also called e3B1, is a central regulator of actin
cytoskeletal reorganization through interactions with
many protein complexes. It is part of WAVE, a
nucleation-promoting factor complex, that links Rac 1
activation to actin polymerization causing lamellipodia
protrusion at the plasma membrane. Abi1 interact with
formins to promote protrusions at the leading edge of
motile cells. It also is a target of alpha4 integrin,
regulating membrane protrusions at sites of integrin
engagement. Abi proteins are adaptor proteins serving as
binding partners and substrates of Abl tyrosine kinases.
They are involved in regulating actin cytoskeletal
reorganization and play important roles in
membrane-ruffling, endocytosis, cell motility, and cell
migration. Abi proteins contain a homeobox homology

>gnl|CDD|219593 pfam07815, Abi_HHR, Abl-interactor HHR. The region featured in
this family is found towards the N-terminus of a number
of adaptor proteins that interact with Abl-family
tyrosine kinases. More specifically, it is termed the
homeo-domain homologous region (HHR), as it is similar
to the DNA-binding region of homeo-domain proteins.
Other homeo-domain proteins have been implicated in
specifying positional information during embryonic
development, and in the regulation of the expression of
cell-type specific genes. The Abl-interactor proteins
are thought to coordinate the cytoplasmic and nuclear
functions of the Abl-family kinases, and seem to be
involved in cytoskeletal reorganisation, but their
precise role remains unclear.

>gnl|CDD|212810 cd11877, SH3_PIX, Src Homology 3 domain of Pak Interactive eXchange
factors. PIX proteins are Rho guanine nucleotide
exchange factors (GEFs), which activate small GTPases by
exchanging bound GDP for free GTP. They act as GEFs for
both Cdc42 and Rac 1, and have been implicated in cell
motility, adhesion, neurite outgrowth, and cell
polarity. Vertebrates contain two proteins from the PIX
subfamily, alpha-PIX and beta-PIX. Alpha-PIX, also
called ARHGEF6, is localized in dendritic spines where
it regulates spine morphogenesis. Mutations in the
ARHGEF6 gene cause X-linked intellectual disability in
humans. Beta-PIX play roles in regulating neuroendocrine
exocytosis, focal adhesion maturation, cell migration,
synaptic vesicle localization, and insulin secretion.
PIX proteins contain an N-terminal SH3 domain followed
by RhoGEF (also called Dbl-homologous or DH) and
Pleckstrin Homology (PH) domains, and a C-terminal
leucine-zipper domain for dimerization. The SH3 domain
of PIX binds to an atypical PxxxPR motif in
p21-activated kinases (PAKs) with high affinity. The
binding of PAKs to PIX facilitate the localization of
PAKs to focal complexes and also localizes PAKs to PIX
targets Cdc43 and Rac, leading to the activation of
PAKs. SH3 domains are protein interaction domains that

are referred to as proline-recognition domains (PRDs).
SH3 domains are less selective and show more diverse
specificity compared to other PRDs. They have been shown
to bind peptide sequences that lack the PxxP motif;
examples include the PxxDY motif of Eps8 and the

(MyoIf) are nonmuscle, unconventional, long tailed,
class I myosins containing an N-terminal motor domain
and a myosin tail with TH1, TH2, and SH3 domains. MyoIe
interacts with the endocytic proteins, dynamin and
synaptojanin-1, through its SH3 domain; it may play a
role in clathrin-dependent endocytosis. In the kidney,
MyoIe is critical for podocyte function and normal
glomerular filtration. Mutations in MyoIe is associated
with focal segmental glomerulosclerosis, a disease
characterized by massive proteinuria and progression to
end-stage kidney disease. MyoIf is predominantly
expressed in the immune system; it plays a role in
immune cell motility and innate immunity. Mutations in
MyoIf may be associated with the loss of hearing. The

proteins that function in exo- and endocytosis, actin
cytoskeletal reorganization, and signal transduction.
They are essential for initiating clathrin-coated pit
formation. They bind to many proteins through their
multidomain structure and facilitate the assembly of
multimeric complexes. Vertebrates contain two ITSN
proteins, ITSN1 and ITSN2, which exist in alternatively
spliced short and long isoforms. The short isoforms
contain two Eps15 homology domains (EH1 and EH2), a
coiled-coil region and five SH3 domains (SH3A-E), while

related proteins. This subfamily includes cortactin,
Abp1 (actin-binding protein 1), hematopoietic lineage
cell-specific protein 1 (HS1), and similar proteins.
These proteins are involved in regulating actin dynamics
through direct or indirect interaction with the Arp2/3
complex, which is required to initiate actin
polymerization. They all contain at least one C-terminal
SH3 domain. Cortactin and HS1 bind Arp2/3 and actin
through an N-terminal region that contains an acidic
domain and several copies of a repeat domain found in
cortactin and HS1. Abp1 binds actin via an N-terminal
actin-depolymerizing factor (ADF) homology domain. Yeast
Abp1 binds Arp2/3 directly through two acidic domains.
Mammalian Abp1 does not directly interact with Arp2/3;
instead, it regulates actin dynamics indirectly by
interacting with dynamin and WASP family proteins. The
C-terminal region of these proteins acts as an adaptor
or scaffold that can connect membrane trafficking and
signaling proteins that bind the SH3 domain within the
actin network. SH3 domains are protein interaction
domains that bind to proline-rich ligands with moderate

hematopoietic system. It plays an important role in T
cell receptor (TCR) signaling by promoting the formation
of the SLP-76:LAT complex, which couples the TCR to the
Ras pathway. It also has roles in antigen-receptor and
tyrosine kinase mediated signaling. GRAP2 is unique from

similar proteins. Family members contain an N-terminal
SH3 domain, a central SH2 domain, and a C-terminal SH3
domain. GRB2/Sem-5/DRK is a critical signaling molecule
that regulates the Ras pathway by linking tyrosine
kinases to the Ras guanine nucleotide releasing protein
Sos (son of sevenless), which converts Ras to the active
GTP-bound state. GRAP2 plays an important role in T cell
receptor (TCR) signaling by promoting the formation of
the SLP-76:LAT complex, which couples the TCR to the Ras
pathway. GRAP acts as a negative regulator of T cell
receptor (TCR)-induced lymphocyte proliferation by
downregulating the signaling to the Ras/ERK pathway. The
C-terminal SH3 domains (SH3c) of GRB2 and GRAP2 have
been shown to bind to classical PxxP motif ligands, as
well as to non-classical motifs. GRB2 SH3c binds Gab2

phagocytic NADPH oxidase complex (also called Nox2 or
gp91phox) and nonphagocytic NADPH oxidase Nox1,
respectively. They play roles in the activation of their
respective NADPH oxidase, which catalyzes the transfer
of electrons from NADPH to molecular oxygen to form
superoxide. Tks proteins are Src substrates and
scaffolding proteins that play important roles in the
formation of podosomes and invadopodia, the dynamic
actin-rich structures that are related to cell migration

Cortactin was originally identified as a substrate of
Src kinase. It is an actin regulatory protein that binds
to the Arp2/3 complex and stabilizes branched actin
filaments. It is involved in cellular processes that
affect cell motility, adhesion, migration, endocytosis,
and invasion. It is expressed ubiquitously except in
hematopoietic cells, where the homolog hematopoietic
lineage cell-specific 1 (HS1) is expressed instead.
Cortactin contains an N-terminal acidic domain, several
copies of a repeat domain found in cortactin and HS1, a
proline-rich region, and a C-terminal SH3 domain. The
N-terminal region interacts with the Arp2/3 complex and
F-actin, and is crucial in regulating branched actin
assembly. Cortactin also serves as a scaffold and
provides a bridge to the actin cytoskeleton for membrane
trafficking and signaling proteins that bind to its SH3
domain. Binding partners for the SH3 domain of cortactin
include dynamin2, N-WASp, MIM, FGD1, among others. SH3

plays a role in clathrin-coated pit (CCP) formation. It
binds to many proteins through its multidomain structure
and facilitate the assembly of multimeric complexes.
ITSN1 localizes in membranous organelles, CCPs, the
Golgi complex, and may be involved in the cell membrane
trafficking system. It exists in alternatively spliced
short and long isoforms. The short isoform contains two
Eps15 homology domains (EH1 and EH2), a coiled-coil
region and five SH3 domains (SH3A-E), while the long
isoform, in addition, contains RhoGEF (also called
Dbl-homologous or DH), Pleckstrin homology (PH) and C2
domains. The fifth SH3 domain (or SH3E) of ITSN1 has
been shown to bind many protein partners including
SGIP1, Sos1, dynamin1/2, CIN85, c-Cbl, SHIP2, N-WASP,
and synaptojanin-1, among others. SH3 domains are
protein interaction domains that bind to proline-rich
ligands with moderate affinity and selectivity,
preferentially to PxxP motifs. They play versatile and
diverse roles in the cell including the regulation of
enzymes, changing the subcellular localization of
signaling pathway components, and mediating the

1, 2, and 3. MLKs 1, 2, and 3 are Serine/Threonine
Kinases (STKs), catalyzing the transfer of the
gamma-phosphoryl group from ATP to S/T residues on
protein substrates. MLKs act as mitogen-activated
protein kinase kinase kinases (MAP3Ks, MKKKs, MAPKKKs),
which phosphorylate and activate MAPK kinases (MAPKKs or
MKKs or MAP2Ks), which in turn phosphorylate and
activate MAPKs during signaling cascades that are
important in mediating cellular responses to
extracellular signals. MLKs play roles in immunity and
inflammation, as well as in cell death, proliferation,
and cell cycle regulation. Little is known about the
specific function of MLK1, also called MAP3K9. It is
capable of activating the c-Jun N-terminal kinase
pathway. Mice lacking both MLK1 and MLK2 are viable,
fertile, and have normal life spans. MLK2, also called
MAP3K10, is abundant in brain, skeletal muscle, and
testis. It functions upstream of the MAPK, c-Jun
N-terminal kinase. It binds hippocalcin, a
calcium-sensor protein that protects neurons against
calcium-induced cell death. Both MLK2 and hippocalcin
may be associated with the pathogenesis of Parkinson's
disease. MLK3, also called MAP3K11, is highly expressed
in breast cancer cells and its signaling through c-Jun
N-terminal kinase has been implicated in the migration,
invasion, and malignancy of cancer cells. It also
functions as a negative regulator of Inhibitor of
Nuclear Factor-KappaB Kinase (IKK) and thus, impacts
inflammation and immunity. MLKs contain an SH3 domain, a
catalytic kinase domain, a leucine zipper, a
proline-rich region, and a CRIB domain that mediates
binding to GTP-bound Cdc42 and Rac. SH3 domains are
protein interaction domains that bind to proline-rich

containing ring finger proteins. This model represents
the first SH3 domain of SH3RF1 (or POSH), SH3RF2 (or
POSHER), SH3RF3 (POSH2), and similar domains. Members of
this family are scaffold proteins that function as E3
ubiquitin-protein ligases. They all contain an
N-terminal RING finger domain and multiple SH3 domains;
SH3RF1 and SH3RF3 have four SH3 domains while SH3RF2 has
three. SH3RF1 plays a role in calcium homeostasis
through the control of the ubiquitin domain protein
Herp. It may also have a role in regulating death
receptor mediated and JNK mediated apoptosis. SH3RF3
interacts with p21-activated kinase 2 (PAK2) and
GTP-loaded Rac1. It may play a role in regulating JNK
mediated apoptosis in certain conditions. SH3RF2 acts as
an anti-apoptotic regulator of the JNK pathway by
binding to and promoting the degradation of SH3RF1. SH3
domains are protein interaction domains that bind to
proline-rich ligands with moderate affinity and
selectivity, preferentially to PxxP motifs. They play

MLK4 is a Serine/Threonine Kinase (STK), catalyzing the
transfer of the gamma-phosphoryl group from ATP to S/T
residues on protein substrates. MLKs act as
mitogen-activated protein kinase kinase kinases (MAP3Ks,
MKKKs, MAPKKKs), which phosphorylate and activate MAPK
kinases (MAPKKs or MKKs or MAP2Ks), which in turn
phosphorylate and activate MAPKs during signaling
cascades that are important in mediating cellular
responses to extracellular signals. MLKs play roles in
immunity and inflammation, as well as in cell death,
proliferation, and cell cycle regulation. The specific
function of MLK4 is yet to be determined. Mutations in
the kinase domain of MLK4 have been detected in
colorectal cancers. MLK4 contains an SH3 domain, a
catalytic kinase domain, a leucine zipper, a
proline-rich region, and a CRIB domain that mediates

p67phox, also called Neutrophil cytosol factor 2
(NCF-2), is a cytosolic subunit of the phagocytic NADPH
oxidase complex (also called Nox2 or gp91phox) which
plays a crucial role in the cellular response to
bacterial infection. NADPH oxidase catalyzes the
transfer of electrons from NADPH to oxygen during
phagocytosis forming superoxide and reactive oxygen
species. p67phox plays a regulatory role and contains
N-terminal TPR, first SH3 (or N-terminal or central

C-terminal SH3 domain, to a proline-rich region of
p47phox and upon activation, this complex assembles with
flavocytochrome b558, the Nox2-p22phox heterodimer.
Concurrently, RacGTP translocates to the membrane and
interacts with the TPR domain of p67phox, which leads to
the activation of NADPH oxidase. The PB1 domain of
p67phox binds to its partner PB1 domain in p40phox, and
this facilitates the assembly of p47phox-p67phox at the

adaptor proteins that play roles in T- and B-cell
adhesion, respectively, and are thus important in the
migration of T- and B-cells to sites of inflammation and
for movement during T-cell conjugation with
antigen-presenting cells. Both SKAP1 and SKAP2 bind to
ADAP (adhesion and degranulation-promoting adaptor
protein), among many other binding partners. They
contain a pleckstrin homology (PH) domain, a C-terminal
SH3 domain, and several tyrosine phosphorylation sites.
The SH3 domain of SKAP1 is necessary for its ability to
regulate T-cell conjugation with antigen-presenting
cells and the formation of LFA-1 clusters. SKAP1 binds
primarily to a proline-rich region of ADAP through its
SH3 domain; its degradation is regulated by ADAP. A
secondary interaction occurs via the ADAP SH3 domain and
the RKxxYxxY motif in SKAP1. SH3 domains are protein
interaction domains that bind to proline-rich ligands
with moderate affinity and selectivity, preferentially
to PxxP motifs. They play versatile and diverse roles in
the cell including the regulation of enzymes, changing
the subcellular localization of signaling pathway
components, and mediating the formation of multiprotein
complex assemblies.

of the p47phox subunit of NADPH oxidase, also called
Neutrophil Cytosolic Factor 1. p47phox, or NCF1, is a
cytosolic subunit of the phagocytic NADPH oxidase
complex (also called Nox2 or gp91phox), which plays a
key role in the ability of phagocytes to defend against
bacterial infections. NADPH oxidase catalyzes the
transfer of electrons from NADPH to oxygen during
phagocytosis forming superoxide and reactive oxygen
species. p47phox is required for activation of NADH
oxidase and plays a role in translocation. It contains
an N-terminal Phox homology (PX) domain, tandem SH3
domains (N-SH3 and C-SH3), a polybasic/autoinhibitory
region, and a C-terminal proline-rich region (PRR). This
model characterizes the second SH3 domain (or C-SH3) of
p47phox. In its inactive state, the tandem SH3 domains
interact intramolecularly with the autoinhibitory
region; upon activation, the tandem SH3 domains are
exposed through a conformational change, resulting in
their binding to the PRR of p22phox and the activation
of NADPH oxidase. SH3 domains are protein interaction
domains that bind to proline-rich ligands with moderate
affinity and selectivity, preferentially to PxxP motifs.
They play versatile and diverse roles in the cell

SH3-containing adapter molecule 1 (SCAM-1). It is an
adaptor protein containing one sorbin homology (SoHo)
and three SH3 domains. Vinexin was first identified as a
vinculin binding protein; it is co-localized with
vinculin at cell-ECM and cell-cell adhesion sites. There

Nebulin. Nebulin is a giant filamentous protein
(600-900 kD) that is expressed abundantly in skeletal
muscle. It binds to actin thin filaments and regulates
its assembly and function. Nebulin was thought to be
part of a molecular ruler complex that is critical in
determining the lengths of actin thin filaments in
skeletal muscle since its length, which varies due to
alternative splicing, correlates with the length of thin
filaments in various muscle types. Recent studies
indicate that nebulin regulates thin filament length by
stabilizing the filaments and preventing
depolymerization. Mutations in nebulin can cause
nemaline myopathy, characterized by muscle weakness
which can be severe and can lead to neonatal lethality.
Nebulin contains an N-terminal LIM domain, many nebulin
repeats/super repeats, and a C-terminal SH3 domain. SH3

amphiphysin proteins from distinct genes. Amphiphysin I
proteins, enriched in the brain and nervous system,
contain domains that bind clathrin, Adaptor Protein
complex 2 (AP2), dynamin, and synaptojanin. They
function in synaptic vesicle endocytosis. Human
autoantibodies to amphiphysin I hinder GABAergic
signaling and contribute to the pathogenesis of
paraneoplastic stiff-person syndrome. Some amphiphysin
II isoforms, also called Bridging integrator 1 (Bin1),
are localized in many different tissues and may function
in intracellular vesicle trafficking. In skeletal
muscle, Bin1 plays a role in the organization and
maintenance of the T-tubule network. Mutations in Bin1
are associated with autosomal recessive centronuclear
myopathy. Amphiphysins contain an N-terminal BAR domain
with an additional N-terminal amphipathic helix (an
N-BAR), a variable central domain, and a C-terminal SH3
domain. The SH3 domain of amphiphysins bind proline-rich

RIMs binding proteins (RBPs, RIM-BPs) associate with
calcium channels present in photoreceptors, neurons, and
hair cells; they interact simultaneously with specific
calcium channel subunits, and active zone proteins, RIM1
and RIM2. RIMs are part of the matrix at the presynaptic
active zone and are associated with synaptic vesicles
through their interaction with the small GTPase Rab3.
RIM-BPs play a role in regulating synaptic transmission
by serving as adaptors and linking calcium channels with
the synaptic vesicle release machinery. RIM-BPs contain
three SH3 domains and two to three fibronectin III
repeats. Invertebrates contain one, while vertebrates
contain at least two RIM-BPs, RIM-BP1 and RIM-BP2.
RIM-BP1 is also called peripheral-type benzodiazapine
receptor associated protein 1 (PRAX-1). Mammals contain
a third protein, RIM-BP3. RIM-BP1 and RIM-BP2 are
predominantly expressed in the brain where they display
overlapping but distinct expression patterns, while
RIM-BP3 is almost exclusively expressed in the testis
and is essential in spermiogenesis. The SH3 domains of
RIM-BPs bind to the PxxP motifs of RIM1, RIM2, and
L-type (alpha1D) and N-type (alpha1B) calcium channel
subunits. SH3 domains are protein interaction domains
that bind to proline-rich ligands with moderate affinity
and selectivity. They play versatile and diverse roles

changing the subcellular localization of signaling
pathway components, and mediating the formation of
multiprotein complex assemblies.

protein product of the dentatorubral-pallidoluysian
atrophy (DRPLA) gene. DRPLA OMIM:125370 is a progressive
neurodegenerative disorder. It is caused by the
expansion of a CAG repeat in the DRPLA gene on
chromosome 12p. This results in an extended
polyglutamine region in atrophin-1, that is thought to
confer toxicity to the protein, possibly through
altering its interactions with other proteins. The
expansion of a CAG repeat is also the underlying defect
in six other neurodegenerative disorders, including
Huntington's disease. One interaction of expanded
polyglutamine repeats that is thought to be pathogenic
is that with the short glutamine repeat in the
transcriptional coactivator CREB binding protein, CBP.
This interaction draws CBP away from its usual nuclear
location to the expanded polyglutamine repeat protein
aggregates that are characteristic of the polyglutamine
neurodegenerative disorders. This interferes with
CBP-mediated transcription and causes cytotoxicity.

Vinexin is also called Sorbs3, SH3P3, and
SH3-containing adapter molecule 1 (SCAM-1). It is an
adaptor protein containing one sorbin homology (SoHo)
and three SH3 domains. Vinexin was first identified as a
vinculin binding protein; it is co-localized with
vinculin at cell-ECM and cell-cell adhesion sites. There
are several splice variants of vinexin: alpha, which
contains the SoHo and three SH3 domains and displays
tissue-specific expression; and beta, which contains
only the three SH3 domains and is widely expressed.
Vinexin alpha stimulates the accumulation of F-actin at
focal contact sites. Vinexin also promotes keratinocyte
migration and wound healing. The SH3 domains of vinexin
have been reported to bind a number of ligands including
vinculin, WAVE2, DLG5, Abl, and Cbl. SH3 domains are

Associated with Focal adhesion kinase 2. GRAF2, also
called Rho GTPase activating protein 10 (ARHGAP10) or
PS-GAP, is a GAP with activity towards Cdc42 and RhoA.
It regulates caspase-activated p21-activated protein
kinase-2 (PAK-2p34). GRAF2 interacts with PAK-2p34,
leading to its stabilization and decrease of cell death.
It is highly expressed in skeletal muscle, and is
involved in alpha-catenin recruitment at cell-cell
junctions. GRAF2 contains an N-terminal BAR domain,
followed by a Pleckstrin homology (PH) domain, a Rho GAP
domain, and a C-terminal SH3 domain. The SH3 domain of
GRAF binds PKNbeta, a target of the small GTPase Rho.
SH3 domains bind to proline-rich ligands with moderate
affinity and selectivity, preferentially to PxxP motifs;
they play a role in the regulation of enzymes by
intramolecular interactions, changing the subcellular
localization of signal pathway components and mediate
multiprotein complex assemblies.

Protein Tyrosine Kinases. Src subfamily members include
Src, Lck, Hck, Blk, Lyn, Fgr, Fyn, Yrk, Yes, and Brk.
Src (or c-Src) proteins are cytoplasmic (or
non-receptor) PTKs which are anchored to the plasma
membrane. They contain an N-terminal SH4 domain with a
myristoylation site, followed by SH3 and SH2 domains, a
tyr kinase domain, and a regulatory C-terminal region
containing a conserved tyr. They are activated by
autophosphorylation at the tyr kinase domain, but are
negatively regulated by phosphorylation at the
C-terminal tyr by Csk (C-terminal Src Kinase). However,
Brk lacks the N-terminal myristoylation sites. Src
proteins are involved in signaling pathways that
regulate cytokine and growth factor responses,
cytoskeleton dynamics, cell proliferation, survival, and
differentiation. They were identified as the first
proto-oncogene products, and they regulate cell
adhesion, invasion, and motility in cancer cells, and
tumor vasculature, contributing to cancer progression
and metastasis. Src kinases are overexpressed in a
variety of human cancers, making them attractive targets
for therapy. They are also implicated in acute
inflammatory responses and osteoclast function. Src,
Fyn, Yes, and Yrk are widely expressed, while Blk, Lck,
Hck, Fgr, Lyn, and Brk show a limited expression
pattern. This subfamily also includes Drosophila Src42A,
Src oncogene at 42A (also known as Dsrc41) which
accumulates at sites of cell-cell or cell-matrix
adhesion, and participates in Drosphila development and
wound healing. It has been shown to promote tube
elongation in the tracheal system, is essential for
proper cell-cell matching during dorsal closure, and
regulates cell-cell contacts in developing Drosophila
eyes. The SH3 domain of Src kinases contributes to
substrate recruitment by binding adaptor
proteins/substrates, and regulation of kinase activity
through an intramolecular interaction. SH3 domains are
protein interaction domains that bind to proline-rich
ligands with moderate affinity and selectivity,
preferentially to PxxP motifs. They play versatile and

similarity at their C-termini, where they harbor a
proline-rich region, four ankyrin (ANK) repeats, and an
SH3 domain. Vertebrates contain three members of the
family: ASPP1, ASPP2, and iASPP. ASPP1 and ASPP2
activate the apoptotic function of the p53 family of
tumor suppressors (p53, p63, and p73), while iASPP is an
oncoprotein that specifically inhibits p53-induced
apoptosis. The expression of ASPP proteins is altered in
tumors; ASPP1 and ASPP2 are downregulated whereas iASPP
is upregulated is some cancer types. ASPP proteins also
bind and regulate protein phosphatase 1 (PP1), and this

with other Src subfamily members, particularly Src. It
also shows some unique functions such as binding to

associates with a number of proteins in different cell
types that Src does not interact with, like JAK2 and
gp130 in pre-adipocytes, and Pyk2 in treated pulmonary
vein endothelial cells. Although the biological function
of Yes remains unclear, it appears to have a role in

trafficking in polarized cells. Src kinases contain an

C-terminal domains of the gamma subunit are represented

Together with TFIID, TFIIA binds to the promoter region;
this is the first step in the formation of a
pre-initiation complex (PIC). Binding of the rest of the
transcription machinery follows this step. After
initiation, the PIC does not completely dissociate from
the promoter. Some components, including TFIIA, remain
attached and re-initiate a subsequent round of

of Intersectin-1. Intersectin-1 (ITSN1) is an adaptor
protein that functions in exo- and endocytosis, actin
cytoskeletal reorganization, and signal transduction. It
plays a role in clathrin-coated pit (CCP) formation. It
binds to many proteins through its multidomain structure
and facilitate the assembly of multimeric complexes.
ITSN1 localizes in membranous organelles, CCPs, the
Golgi complex, and may be involved in the cell membrane
trafficking system. It exists in alternatively spliced
short and long isoforms. The short isoform contains two
Eps15 homology domains (EH1 and EH2), a coiled-coil
region and five SH3 domains (SH3A-E), while the long
isoform, in addition, contains RhoGEF (also called
Dbl-homologous or DH), Pleckstrin homology (PH) and C2
domains. The second SH3 domain (or SH3B) of ITSN1 has
been shown to bind WNK and CdGAP. SH3 domains are
protein interaction domains that bind to proline-rich
ligands with moderate affinity and selectivity,
preferentially to PxxP motifs. They play versatile and
diverse roles in the cell including the regulation of
enzymes, changing the subcellular localization of
signaling pathway components, and mediating the
formation of multiprotein complex assemblies.

Palmitoylated 5 (or MAGUK p55 subfamily member 5).
MPP5, also called PALS1 (Protein associated with Lin7)
or Nagie oko protein in zebrafish or Stardust in
Drosophila, is a scaffolding protein which associates
with Crumbs homolog 1 (CRB1), CRB2, or CRB3 through its
PDZ domain and with PALS1-associated tight junction
protein (PATJ) or multi-PDZ domain protein 1 (MUPP1)
through its L27 domain. The resulting tri-protein
complexes are core proteins of the Crumb complex, which
localizes at tight junctions or subapical regions, and
is involved in the maintenance of apical-basal polarity
in epithelial cells and the morphogenesis and function
of photoreceptor cells. MPP5 is critical for the proper
stratification of the retina and is also expressed in T
lymphocytes where it is important for TCR-mediated
activation of NFkB. Drosophila Stardust exists in
several isoforms, some of which show opposing functions
in photoreceptor cells, which suggests that the relative
ratio of different Crumbs complexes regulates
photoreceptor homeostasis. MPP5 contains two L27 domains
followed by the core of three domains characteristic of
MAGUK (membrane-associated guanylate kinase) proteins:
PDZ, SH3, and guanylate kinase (GuK). In addition, it
also contains the Hook (Protein 4.1 Binding) motif in
between the SH3 and GuK domains. The GuK domain in MAGUK
proteins is enzymatically inactive; instead, the domain
mediates protein-protein interactions and associates
intramolecularly with the SH3 domain. SH3 domains are
protein interaction domains that bind to proline-rich
ligands with moderate affinity and selectivity,
preferentially to PxxP motifs. They play versatile and
diverse roles in the cell including the regulation of
enzymes, changing the subcellular localization of
signaling pathway components, and mediating the
formation of multiprotein complex assemblies.

>gnl|CDD|212941 cd12008, SH3_Src, Src homology 3 domain of Src Protein Tyrosine
Kinase. Src (or c-Src) is a cytoplasmic (or
non-receptor) PTK and is the vertebrate homolog of the
oncogenic protein (v-Src) from Rous sarcoma virus.
Together with other Src subfamily proteins, it is
involved in signaling pathways that regulate cytokine
and growth factor responses, cytoskeleton dynamics, cell
proliferation, survival, and differentiation. Src also
play a role in regulating cell adhesion, invasion, and
motility in cancer cells, and tumor vasculature,
contributing to cancer progression and metastasis.
Elevated levels of Src kinase activity have been
reported in a variety of human cancers. Several
inhibitors of Src have been developed as anti-cancer
drugs. Src is also implicated in acute inflammatory
responses and osteoclast function. Src kinases contain
an N-terminal SH4 domain with a myristoylation site,
followed by SH3 and SH2 domains, a tyr kinase domain,
and a regulatory C-terminal region containing a
conserved tyr. They are activated by autophosphorylation
at the tyr kinase domain, but are negatively regulated
by phosphorylation at the C-terminal tyr by Csk
(C-terminal Src Kinase). The SH3 domain of Src kinases
contributes to substrate recruitment by binding adaptor
proteins/substrates, and regulation of kinase activity
through an intramolecular interaction. SH3 domains are
protein interaction domains that bind to proline-rich
ligands with moderate affinity and selectivity,
preferentially to PxxP motifs. They play versatile and

c-Jun N-terminal kinase (JNK) signaling pathways. They
bind to components of Mitogen-activated protein kinase
(MAPK) pathways such as JNK, MKK, and several MAP3Ks
such as MLK and DLK. There are four JIPs (JIP1-4); all
contain a JNK binding domain. JIP1 and JIP2 also contain
SH3 and Phosphotyrosine-binding (PTB) domains. Both are
highly expressed in the brain and pancreatic beta-cells.
JIP1 functions as an adaptor linking motor to cargo
during axonal transport and also is involved in
regulating insulin secretion. JIP2 form complexes with
fibroblast growth factor homologous factors (FHFs),
which facilitates activation of the p38delta MAPK. The
SH3 domain of JIP1 homodimerizes at the interface
usually involved in proline-rich ligand recognition,
despite the lack of this motif in the domain itself. SH3
domains are protein interaction domains that bind to
proline-rich ligands with moderate affinity and

Mediator is a large complex of up to 33 proteins that is
conserved from plants through fungi to humans - the
number and representation of individual subunits varying
with species. It is arranged into four different
sections, a core, a head, a tail and a kinase-activity
part, and the number of subunits within each of these is
what varies with species. Overall, Mediator regulates
the transcriptional activity of RNA polymerase II but it
would appear that each of the four different sections
has a slightly different function. Med13 is part of the
ancillary kinase module, together with Med12, CDK8 and
CycC, which in yeast is implicated in transcriptional
repression, though most of this activity is likely
attributable to the CDK8 kinase. The large Med12 and
Med13 proteins are required for specific developmental
processes in Drosophila, zebrafish, and Caenorhabditis
elegans but their biochemical functions are not
understood.

MPP1, also called 55 kDa erythrocyte membrane protein
(p55), is a ubiquitously-expressed scaffolding protein
that plays roles in regulating neutrophil polarity, cell
shape, hair cell development, and neural development and
patterning of the retina. It was originally identified
as an erythrocyte protein that stabilizes the actin
cytoskeleton to the plasma membrane by forming a complex
with 4.1R protein and glycophorin C. MPP1 is one of
seven vertebrate homologs of the Drosophila Stardust
protein, which is required in establishing cell
polarity, and it contains the three domains
characteristic of MAGUK (membrane-associated guanylate
kinase) proteins: PDZ, SH3, and guanylate kinase (GuK).
In addition, it also contains the Hook (Protein 4.1
Binding) motif in between the SH3 and GuK domains. The
GuK domain in MAGUK proteins is enzymatically inactive;
instead, the domain mediates protein-protein
interactions and associates intramolecularly with the

>gnl|CDD|197891 smart00818, Amelogenin, Amelogenins, cell adhesion proteins, play a
role in the biomineralisation of teeth. They seem to
regulate formation of crystallites during the secretory
stage of tooth enamel development and are thought to
play a major role in the structural organisation and
mineralisation of developing enamel. The extracellular
matrix of the developing enamel comprises two major
classes of protein: the hydrophobic amelogenins and the
acidic enamelins. Circular dichroism studies of porcine
amelogenin have shown that the protein consists of 3
discrete folding units: the N-terminal region appears to
contain beta-strand structures, while the C-terminal
region displays characteristics of a random coil
conformation. Subsequent studies on the bovine protein
have indicated the amelogenin structure to contain a
repetitive beta-turn segment and a "beta-spiral" between
Gln112 and Leu138, which sequester a (Pro, Leu, Gln)
rich region. The beta-spiral offers a probable site for
interactions with Ca2+ ions. Muatations in the human
amelogenin gene (AMGX) cause X-linked hypoplastic
amelogenesis imperfecta, a disease characterised by
defective enamel. A 9bp deletion in exon 2 of AMGX
results in the loss of codons for Ile5, Leu6, Phe7 and
Ala8, and replacement by a new threonine codon,
disrupting the 16-residue (Met1-Ala16) amelogenin signal
peptide.

>gnl|CDD|213014 cd12081, SH3_CASK, Src Homology 3 domain of
Calcium/calmodulin-dependent Serine protein Kinase.
CASK is a scaffolding protein that is highly expressed
in the mammalian nervous system and plays roles in
synaptic protein targeting, neural development, and gene
expression regulation. CASK interacts with many
different binding partners including parkin, neurexin,
syndecans, calcium channel proteins, caskin, among
others, to perform specific functions in different
subcellular locations. Disruption of the CASK gene in
mice results in neonatal lethality while mutations in
the human gene have been associated with X-linked mental
retardation. Drosophila CASK is associated with both
pre- and postsynaptic membranes and is crucial in
synaptic transmission and vesicle cycling. CASK contains
an N-terminal calmodulin-dependent kinase (CaMK)-like
domain, two L27 domains, followed by the core of three
domains characteristic of MAGUK (membrane-associated
guanylate kinase) proteins: PDZ, SH3, and guanylate
kinase (GuK). In addition, it also contains the Hook
(Protein 4.1 Binding) motif in between the SH3 and GuK
domains. The GuK domain in MAGUK proteins is
enzymatically inactive; instead, the domain mediates
protein-protein interactions and associates
intramolecularly with the SH3 domain. SH3 domains are
protein interaction domains that bind to proline-rich
ligands with moderate affinity and selectivity,
preferentially to PxxP motifs. They play versatile and
diverse roles in the cell including the regulation of
enzymes, changing the subcellular localization of
signaling pathway components, and mediating the
formation of multiprotein complex assemblies.

CSK is a cytoplasmic (or nonreceptor) tyr kinase
containing the Src homology domains, SH3 and SH2,
N-terminal to the catalytic tyr kinase domain. They
negatively regulate the activity of Src kinases that are
anchored to the plasma membrane. To inhibit Src kinases,
CSK is translocated to the membrane via binding to
specific transmembrane proteins, G-proteins, or adaptor
proteins near the membrane. CSK catalyzes the tyr
phosphorylation of the regulatory C-terminal tail of Src
kinases, resulting in their inactivation. It is
expressed in a wide variety of tissues and plays a role,
as a regulator of Src, in cell proliferation, survival,
and differentiation, and consequently, in cancer
development and progression. In addition, CSK also shows
Src-independent functions. It is a critical component in
G-protein signaling, and plays a role in cytoskeletal
reorganization and cell migration. SH3 domains are
protein interaction domains that bind to proline-rich
ligands with moderate affinity and selectivity,
preferentially to PxxP motifs. They play versatile and
diverse roles in the cell including the regulation of
enzymes, changing the subcellular localization of
signaling pathway components, and mediating the

ABF1 is a sequence-specific DNA binding protein involved
in transcription activation, gene silencing and
initiation of DNA replication. ABF1 is known to remodel
chromatin, and it is proposed that it mediates its
effects on transcription and gene expression by
modifying local chromatin architecture. These functions
require a conserved stretch of 20 amino acids in the
C-terminal region of ABF1 (amino acids 639 to 662 S.
cerevisiae). The N-terminal two thirds of the protein
are necessary for DNA binding, and the N-terminus (amino
acids 9 to 91 in S. cerevisiae) is thought to contain a
novel zinc-finger motif which may stabilise the protein
structure.

Peroxisomal biogenesis factor 13. PEX13 is a peroxin
and is required for protein import into the peroxisomal
matrix and membrane. It is an integral membrane protein
that is essential for the localization of PEX14 and the
import of proteins containing the peroxisome matrix
targeting signals, PTS1 and PTS2. Mutations of the PEX13
gene in humans lead to a wide range of peroxisome
biogenesis disorders (PBDs), the most severe of which is
known as Zellweger syndrome (ZS), a severe multisystem
disorder characterized by hypotonia, psychomotor
retardation, and neuronal migration defects. PEX13
contains two transmembrane regions and a C-terminal SH3
domain. SH3 domains are protein interaction domains that
bind to proline-rich ligands with moderate affinity and
selectivity, preferentially to PxxP motifs. They play
versatile and diverse roles in the cell including the
regulation of enzymes, changing the subcellular
localization of signaling pathway components, and
mediating the formation of multiprotein complex
assemblies.

Palmitoylated (or MAGUK p55 subfamily member) proteins.
The MPP/p55 subfamily of MAGUK (membrane-associated
guanylate kinase) proteins includes at least eight
vertebrate members (MPP1-7 and CASK), four Drosophila
proteins (Stardust, Varicose, CASK and Skiff), and other
similar proteins; they all contain one each of the core
of three domains characteristic of MAGUK proteins: PDZ,
SH3, and guanylate kinase (GuK). In addition, most
members except for MPP1 contain N-terminal L27 domains
and some also contain a Hook (Protein 4.1 Binding) motif
in between the SH3 and GuK domains. CASK has an
additional calmodulin-dependent kinase (CaMK)-like
domain at the N-terminus. Members of this subfamily are
scaffolding proteins that play important roles in
regulating and establishing cell polarity, cell
adhesion, and synaptic targeting and transmission, among
others. The GuK domain in MAGUK proteins is
enzymatically inactive; instead, the domain mediates
protein-protein interactions and associates
intramolecularly with the SH3 domain. SH3 domains are
protein interaction domains that bind to proline-rich
ligands with moderate affinity and selectivity,

This model represents the CopA copper resistance protein

oxidoreductase) and L-ascorbate oxidase, both
copper-containing enzymes. Most members have a typical
TAT (twin-arginine translocation) signal sequence with
an Arg-Arg pair. Twin-arginine translocation is observed
for a large number of periplasmic proteins that cross
the inner membrane with metal-containing cofactors
already bound. The combination of copper-binding sites
and TAT translocation motif suggests a mechansism of
resistance by packaging and export [Cellular processes,

as dystrophin and YAP (Yes-associated protein). This is
the WW-domain binding protein WWbp via PY and PY_like

suggests a potential regulatory role for tyrosine
phosphorylation in modulating WW domain-ligand
interactions. Given the likelihood that WWP1 and WWP2
function as E3 ubiquitin-protein ligases, it is possible
that initial substrate-specific recognition occurs via
WW domain-substrate protein interaction followed by
