>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.

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|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:

>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.

>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

Yersinia pestis murine toxin-like proteins. Putative
catalytic domain, repeat 1, of Yersinia pestis murine
toxin (Ymt), a plasmid-encoded phospholipase D (PLD, EC
3.1.4.4), and similar proteins. Ymt is important in
order for Yersinia pestis to survive and spread. It is
toxic to mice and rats but not to other animals. It is
not a conventional secreted exotoxin, but a cytoplasmic
protein that is released upon bacterial lysis. Ymt may
be active as a dimer. The monomeric Ymt consists of two
catalytic domains, each of which contains one copy of
the conserved HKD motif (H-x-K-x(4)-D, where x
represents any amino acid residue). Two HKD motifs from
two domains form a single active site. Ymt has PLD-like
activity and has been classified into the PLD
superfamily. It hydrolyzes the terminal phosphodiester
bond in several phospholipids, with preference for
phosphatidylethanolamine (PE) over phosphatidylcholine
(PC) and phosphatidylserine (PS). Like other PLD
enzymes, Ymt may utilize a common two-step ping-pong
catalytic mechanism involving an enzyme-substrate
intermediate to cleave phosphodiester bonds. The two
histidine residues from the two HKD motifs play key
roles in the catalysis. Upon substrate binding, a
histidine residue from one HKD motif could function as
the nucleophile, attacking the phosphodiester bond to
create a covalent phosphohistidine intermediate, while
the other histidine residue from the second HKD motif
could serve as a general acid, stabilizing the leaving
group. In terms of sequence similarity, Ymt is closely
related to Streptomyces PLDs.

>gnl|CDD|187632 cd05374, 17beta-HSD-like_SDR_c, 17beta hydroxysteroid
dehydrogenase-like, classical (c) SDRs.
17beta-hydroxysteroid dehydrogenases are a group of
isozymes that catalyze activation and inactivation of
estrogen and androgens. SDRs are a functionally diverse
family of oxidoreductases that have a single domain with
a structurally conserved Rossmann fold (alpha/beta
folding pattern with a central beta-sheet), an
NAD(P)(H)-binding region, and a structurally diverse
C-terminal region. Classical SDRs are typically about
250 residues long, while extended SDRs are approximately
350 residues. Sequence identity between different SDR
enzymes are typically in the 15-30% range, but the
enzymes share the Rossmann fold NAD-binding motif and
characteristic NAD-binding and catalytic sequence
patterns. These enzymes catalyze a wide range of
activities including the metabolism of steroids,
cofactors, carbohydrates, lipids, aromatic compounds,
and amino acids, and act in redox sensing. Classical
SDRs have an TGXXX[AG]XG cofactor binding motif and a
YXXXK active site motif, with the Tyr residue of the
active site motif serving as a critical catalytic
residue (Tyr-151, human 15-hydroxyprostaglandin
dehydrogenase (15-PGDH) numbering). In addition to the
Tyr and Lys, there is often an upstream Ser (Ser-138,
15-PGDH numbering) and/or an Asn (Asn-107, 15-PGDH
numbering) contributing to the active site; while
substrate binding is in the C-terminal region, which
determines specificity. The standard reaction mechanism
is a 4-pro-S hydride transfer and proton relay involving
the conserved Tyr and Lys, a water molecule stabilized
by Asn, and nicotinamide. Extended SDRs have additional
elements in the C-terminal region, and typically have a
TGXXGXXG cofactor binding motif. Complex (multidomain)
SDRs such as ketoreductase domains of fatty acid
synthase have a GGXGXXG NAD(P)-binding motif and an
altered active site motif (YXXXN). Fungal type ketoacyl
reductases have a TGXXXGX(1-2)G NAD(P)-binding motif.
Some atypical SDRs have lost catalytic activity and/or
have an unusual NAD(P)-binding motif and missing or
unusual active site residues. Reactions catalyzed within
the SDR family include isomerization, decarboxylation,
epimerization, C=N bond reduction, dehydratase activity,
dehalogenation, Enoyl-CoA reduction, and
carbonyl-alcohol oxidoreduction.

>gnl|CDD|241350 cd13196, FERM_C_JAK, Janus kinase (JAK) FERM domain C-lobe. JAK
(also called Just Another Kinase) is a family of
intracellular, non-receptor tyrosine kinases that
transduce cytokine-mediated signals via the JAK-STAT
pathway. The JAK family in mammals consists of 4
members: JAK1, JAK2, JAK3 and TYK2. JAKs are composed of
seven JAK homology (JH) domains (JH1-JH7) . The
C-terminal JH1 domain is the main catalytic domain,
followed by JH2, which is often referred to as a
pseudokinase domain, followed by JH3-JH4 which is
homologous to the SH2 domain, and lastly JH5-JH7 which
is a FERM domain. Named after Janus, the two-faced
Roman god of doorways, JAKs possess two near-identical
phosphate-transferring domains; one which displays the
kinase activity (JH1), while the other negatively
regulates the kinase activity of the first (JH2). The
FERM domain has a cloverleaf tripart structure (FERM_N,
FERM_M, FERM_C/N, alpha-, and C-lobe/A-lobe,A-lobe,
B-lobe, C-lobe/F1, F2, F3). The C-lobe/F3 within the
FERM domain is part of the PH domain family. The FERM
domain is found in the cytoskeletal-associated proteins
such as ezrin, moesin, radixin, 4.1R, and merlin. These
proteins provide a link between the membrane and
cytoskeleton and are involved in signal transduction
pathways. The FERM domain is also found in protein
tyrosine phosphatases (PTPs) , the tyrosine kinases FAK
and JAK, in addition to other proteins involved in
signaling. This domain is structurally similar to the PH
and PTB domains and consequently is capable of binding
to both peptides and phospholipids at different sites.
