>gnl|CDD|241310 cd10574, EVH1_SPRED-like, Sprouty-related EVH1
domain-containing-like proteins EVH1 domain. The Spred
family has the following domains: an N-terminal EVH1
domain, a unique KBD (c-Kit kinase binding) domain which
that is phosphorylated by the stem cell factor receptor
c-Kit, and a C-terminal cysteine-rich SPR
(Sprouty-related) domain which is involved in membrane
localization. There are 3 Spred proteins: Spred1 which
interacts with both Ras and Raf through its SPR domain;
Spred2 which is the most abundant isoform; and Spred3
which has a non-functional KBD and maintains the
inhibitory action on Raf. Legius syndrome is caused by
heterozygous mutations in Spred1. Both EVH1 and SPR
domains are involved in the inhibition of the MAP kinase
pathway by Spred proteins. The specific function of the
Spred2 EVH1 domain is unknown and there are no known
interacting proteins to date. It is thought that its
EVH1 domain will have a fourth distinct peptide binding
mechanism within the EVH1 family. The EVH1 domains are
part of the PH domain superamily. There are 5 EVH1
subfamilies: Enables/VASP, Homer/Vesl, WASP, Dcp1, and
Spred. Ligands are known for three of the EVH1
subfamilies, all of which bind proline-rich sequences:
the Enabled/VASP family binds to FPPPP peptides, the
Homer/Vesl family binds PPxxF peptides, and the WASP
family binds LPPPEP peptides. EVH1 has a PH-like fold,
despite having minimal sequence similarity to PH or PTB
domains.

>gnl|CDD|241243 cd01207, EVH1_Ena_VASP-like, Enabled/VASP family EVH1 domain.
Ena/VASP family includes proteins such as:
Vasodilator-stimulated phosphoprotein (VASP), enabled
gene product from Drosophila (Ena), mammalian enabled
(Mena) and Ena/VASP-Like protein (EVL) localize to focal
adhesions and to sites of actin filament dynamics. These
proteins share a common modular organization with a
highly conserved N- and C-terminal domains, termed
Ena/VASP homology domains 1 and 2 (EVH1 and EVH2), that
are separated by a central proline-rich domain. The EVH1
domain binds to other proteins at proline rich
sequences. The majority of Ena-VASP type EVH1 domains
recognize FPPPP motifs such as in the focal adhesion
proteins zyxin and vinculin, and the ActA surface
protein of Listeria monocytogenes, however the LIM3
domain of Tes lacks the FPPPP motif but still binds the
EVH1 domain of Mena. It has a PH-like fold, despite
having minimal sequence similarity to PH or PTB domains.
EVH2 mediates oligomerization within the family. The
proline-rich region binds SH3 and WW domains as well as
profilin, a protein that regulates actin filament
dynamics. The EVH1 domains are part of the PH domain
superamily. There are 5 EVH1 subfamilies: Enables/VASP,
Homer/Vesl, WASP, Dcp1, and Spred. Ligands are known
for three of the EVH1 subfamilies, all of which bind
proline-rich sequences: the Enabled/VASP family binds to
FPPPP peptides, the Homer/Vesl family binds PPxxF
peptides, and the WASP family binds LPPPEP peptides.
EVH1 has a PH-like fold, despite having minimal sequence
similarity to PH or PTB domains.

>gnl|CDD|144235 pfam00568, WH1, WH1 domain. WASp Homology domain 1 (WH1) domain.
WASP is the protein that is defective in Wiskott-Aldrich
syndrome (WAS). The majority of point mutations occur
within the amino- terminal WH1 domain. The metabotropic
glutamate receptors mGluR1alpha and mGluR5 bind a
protein called homer, which is a WH1 domain homologue. A
subset of WH1 domains has been termed a "EVH1" domain
and appear to bind a polyproline motif.

>gnl|CDD|241241 cd01205, EVH1_WASP-like, WASP family proteins EVH1 domain. The
Wiskott-Aldrich Syndrome Protein (WASP; also called
Bee1p) and its homolog N (neuronal)-WASP are signal
transduction proteins that promote actin polymerization
in response to upstream intracellular signals. WAS is an
X-linked recessive disease, characterized by eczema,
immunodeficiency, and thrombocytopenia. The majority of
patients with WAS, or a milder version of the disorder,
X-linked thrombocytopenia (XLT), have point mutations in
the EVH1 domain of WASP. WASP is an actin regulatory
protein consisting of an N-terminal EVH1 domain called
WH1 which binds LPPPEP peptides, a basic region (B), a
GTP binding domain (GBP), a proline rich region, a WH2
domain, and a verprolin-cofilin-acidic motif (VCA) which
activates the actin-related protein (Arp)2/3 actin
nucleating complex. The B, GBD, and the proline-rich
region are involved in autoinhibitory interactions that
repress or block the activity of the VCA. Yeast members
lack the GTP binding domain. The EVH1 domains are part
of the PH domain superamily. There are 5 EVH1
subfamilies: Enables/VASP, Homer/Vesl, WASP, Dcp1, and
Spred. Ligands are known for three of the EVH1
subfamilies, all of which bind proline-rich sequences:
the Enabled/VASP family binds to FPPPP peptides, the
Homer/Vesl family binds PPxxF peptides, and the WASP
family binds LPPPEP peptides. EVH1 has a PH-like fold,
despite having minimal sequence similarity to PH or PTB
domains.

>gnl|CDD|241242 cd01206, EVH1_Homer_Vesl, Homer/Vesl family proteins EVH1 domain.
Homer/Vesl proteins are synaptic scaffolding proteins,
required for long-term potentiation, a form of synaptic
plasticity thought to underlie memory formation. They
contains an N-terminal EVH1 domain and bind to both
neurotransmitter receptors, such as the metabotropic
group 1 glutamate receptor (mGluR) and to other
scaffolding proteins via PPXXF motifs, in order to
target them to the synaptic junction. These mGluRs
possess a long C-terminal intracellular tail that may
be important for subcellular localization of the
receptor. The C-terminus is also the site of binding by
the immediate early gene (IEG), Homer 1a. In contrast
to Homer 1a, other Homer members additionally encode a
C-terminal coiled-coil (CC) domain and form multivalent
complexes that bind group 1 mGluRs. Homer 1a competes
with constitutively expressed CC-Homers to modify the
association of group 1 mGluRs with CC-Homer complexes.
Since Homer proteins are strikingly enriched at the
postsynaptic density (PSD), these observations suggest
a role for the Homer family in regulating synaptic
metabotropic receptor function. PSD-Zip45 (also named
Homer 1c/Vesl-1L) has an EVH1 domain with a longer
alpha-helix and its linking part included in the
conserved region of Homer 1 (CRH1) interacts with the
EVH1 domain of the neighbour CRH1 molecule in the
crystal, suggesting that the EVH1 domain recognizes the
PPXXF motif found in the binding partners, and the
SPLTP sequence (P-motif) in the linking region of the
CRH1. The two types of binding are partly overlapped in
the EVH1 domain, implying a mechanism to regulate
multimerization of Homer 1 family proteins. Homer 2
and Homer 3 are negative regulators of T cell
activation. They bind the nuclear factor of activated T
cells (NFAT) and compete with calcineurin binding. NFAT
plays a critical role in calcium-dependent signaling in
other cell types, including muscle and neurons.
Homer-NFAT binding is also antagonized by active
serine-threonine kinase AKT, enhancing TCR signaling
via calcineurin-dependent dephosphorylation of NFAT
resulting in changes in cytokine expression and an
increase in effector-memory T cell populations in
Homer-deficient mice. The EVH1 domains are part of the
PH domain superamily. There are 5 EVH1 subfamilies:
Enables/VASP, Homer/Vesl, WASP, Dcp1, and Spred.
Ligands are known for three of the EVH1 subfamilies,
all of which bind proline-rich sequences: the
Enabled/VASP family binds to FPPPP peptides, the
Homer/Vesl family binds PPxxF peptides, and the WASP
family binds LPPPEP peptides. EVH1 has a PH-like fold,
despite having minimal sequence similarity to PH or PTB
domains.
