Phosphotyrosine-binding (PTB) domain. JIP is a
mitogen-activated protein kinase scaffold protein. JIP
consists of a C-terminal SH3 domain, followed by a PTB
domain. PTB domains have a common PH-like fold and are
found in various eukaryotic signaling molecules. This
domain was initially shown to binds peptides with a NPXY
motif with differing requirements for phosphorylation of
the tyrosine, although more recent studies have found
that some types of PTB domains can bind to peptides lack
tyrosine residues altogether. In contrast to SH2
domains, which recognize phosphotyrosine and adjacent
carboxy-terminal residues, PTB-domain binding
specificity is conferred by residues amino-terminal to
the phosphotyrosine. PTB domains are classified into
three groups: phosphotyrosine-dependent Shc-like,
phosphotyrosine-dependent IRS-like, and
phosphotyrosine-independent Dab-like PTB domains. This
cd is part of the Dab-like subgroup.

>gnl|CDD|212735 cd11801, SH3_JIP1_like, Src homology 3 domain of JNK-interacting
proteins 1 and 2, and similar domains. JNK-interacting
proteins (JIPs) function as scaffolding proteins for
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
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|241315 cd13161, PTB_TK_HMTK, Tyrosine-specific kinase/HM-motif TK
(TM/HMTK) Phosphotyrosine-binding (PTB) PH-like fold.
TK kinases catalyzes the transfer of the terminal
phosphate of ATP to a specific tyrosine residue on its
target protein. TK kinases play significant roles in
development and cell division. Tyrosine-protein kinases
can be divided into two subfamilies: receptor tyrosine
kinases, which have an intracellular tyrosine kinase
domain, a transmembrane domain and an extracellular
ligand-binding domain; and non-receptor (cytoplasmic)
tyrosine kinases, which are soluble, cytoplasmic
kinases. In HMTK the conserved His-Arg-Asp sequence
within the catalytic loop is replaced by a His-Met
sequence. TM/HMTK have are 2-3 N-terminal PTB domains.
PTB domains in TKs are thought to function analogously
to the membrane targeting (PH, myristoylation) and pTyr
binding (SH2) domains of Src subgroup kinases. PTB
domains have a common PH-like fold and are found in
various eukaryotic signaling molecules. This domain was
initially shown to binds peptides with a NPXY motif with
differing requirements for phosphorylation of the
tyrosine, although more recent studies have found that
some types of PTB domains can bind to peptides lack
tyrosine residues altogether. In contrast to SH2

three groups: phosphotyrosine-dependent Shc-like,
phosphotyrosine-dependent IRS-like, and

subfamily is composed of the second SH3 domain (SH3B) of
CD2AP, CIN85 (Cbl-interacting protein of 85 kDa), and
similar domains. CD2AP and CIN85 are adaptor proteins
that bind to protein partners and assemble complexes
that have been implicated in T cell activation, kidney
function, and apoptosis of neuronal cells. They also
associate with endocytic proteins, actin cytoskeleton
components, and other adaptor proteins involved in
receptor tyrosine kinase (RTK) signaling. CD2AP and the
main isoform of CIN85 contain three SH3 domains, a
proline-rich region, and a C-terminal coiled-coil
domain. All of these domains enable CD2AP and CIN85 to
bind various protein partners and assemble complexes
that have been implicated in many different functions.
SH3B of both proteins have been shown to bind to Cbl. In
the case of CD2AP, its SH3B binds to Cbl at a site
distinct from the c-Cbl/SH3A binding site. The CIN85
SH3B also binds ubiquitin. 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

requires Bch1p and Bud7p, which are Chs5p-Arf1p binding
proteins, for localization to the plasma membrane. It
acts as a scaffold protein to assemble a cell surface
complex which is involved in septum degradation and
inhibition of the NOG pathway to promote cell fusion.
The SH3 domain of Fus1p interacts with Bin1p, a formin
that controls the assembly of actin cables in response
to Cdc42 signaling. It has been shown to bind the motif,
R(S/T)(S/T)SL, instead of PxxP motifs. SH3 domains are
protein interaction domains that bind to proline-rich

Phosphotyrosine-binding (PTB) PH-like fold. RGS12
functions as a GTPase-activating protein and a
transcriptional repressor. It is thought to play a role
in tumorigenesis. RGS12 specifically interacts with
guanine nucleotide-binding protein G(i), alpha-1 subunit
and guanine nucleotide-binding protein G(k) subunit
alpha. RGS proteins are multi-functional,
GTPase-accelerating proteins that promote GTP hydrolysis
by the alpha subunit of heterotrimeric G proteins,
thereby inactivating the G protein and rapidly switching
off G protein-coupled receptor signalling pathways. Upon
activation by GPCRs, heterotrimeric G proteins exchange
GDP for GTP, are released from the receptor, and
dissociate into free, active GTP-bound alpha subunit and
beta-gamma dimer, both of which activate downstream
effectors. The response is terminated upon GTP
hydrolysis by the alpha subunit, which can then bind the
beta-gamma dimer and the receptor. RGS proteins markedly
reduce the lifespan of GTP-bound alpha subunits by
stabilizing the G protein transition state. PTB domains

proteins. Nck adaptor proteins regulate actin
cytoskeleton dynamics by linking proline-rich effector
molecules to protein tyrosine kinases and phosphorylated
signaling intermediates. They contain three SH3 domains
and a C-terminal SH2 domain. They function downstream of
the PDGFbeta receptor and are involved in Rho GTPase
signaling and actin dynamics. Vertebrates contain two
Nck adaptor proteins: Nck1 (also called Nckalpha) and
Nck2 (also called Nckbeta or Growth factor
receptor-bound protein 4, Grb4), which show partly
overlapping functions but also bind distinct targets.
Their SH3 domains are involved in recruiting downstream
effector molecules, such as the N-WASP/Arp2/3 complex,
which when activated induces actin polymerization that
results in the production of pedestals, or protrusions
of the plasma membrane. The second SH3 domain of Nck
appears to prefer ligands containing the APxxPxR motif.
SH3 domains are protein interaction domains that usually
bind to proline-rich ligands with moderate affinity and
selectivity, preferentially a PxxP motif. 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.

proteins Phosphotyrosine-binding (PTB) domain. The
TBC1D1-like members here include TBC1D1, TBC1D4 (also
called Akt substrate of 160 kDa or AS160), and pollux
(PLX), a calmodulin-binding protein, and are thought to
have a role in regulating cell growth and
differentiation. These proteins are thought to function
as GTPase-activating protein for Rab family protein(s).
They may play a role in the cell cycle and
differentiation of various tissues. They all contain an
N-terminal PTB domain, a calmodulin CBD domain, and a
C-terminal TBC domain which is thought to be a GTPase
activator protein of Rab-like small GTPases. Recently,
TBC1D1 and TBC1D4 were recognized to potentially link
the proximal signalling of insulin and/or exercise with
GLUT4. TBC1D4 is thought to be involved in
contraction-stimulated glucose uptake, but
TBC1D4-independent mechanisms (potentially involving
TBC1D1) are likely to be essential for most of the
contraction's effect. PTB domains have a common PH-like
fold and are found in various eukaryotic signaling
molecules. This domain was initially shown to binds
peptides with a NPXY motif with differing requirements
for phosphorylation of the tyrosine, although more
recent studies have found that some types of PTB domains
can bind to peptides lack tyrosine residues altogether.
In contrast to SH2 domains, which recognize
phosphotyrosine and adjacent carboxy-terminal residues,
PTB-domain binding specificity is conferred by residues
amino-terminal to the phosphotyrosine. PTB domains are
classified into three groups: phosphotyrosine-dependent
Shc-like, phosphotyrosine-dependent IRS-like, and
phosphotyrosine-independent Dab-like PTB domains. This
cd is part of the Dab-like subgroup.

4,6-dehydratase/5-epimerase. The FnlA enzyme is the
first step in the biosynthesis of UDP-FucNAc from
UDP-GlcNAc in E. coli (along with FnlB and FnlC). The
proteins identified by this model include FnlA homologs
in the O-antigen clusters of O4, O25, O26, O29 (Shigella
D11), O118, O145 and O172 serotype strains, all of which
produce O-antigens containing FucNAc (or the further
modified FucNAm). A homolog from Pseudomonas aerugiosa
serotype O11, WbjB, also involved in the biosynthesis of
UDP-FucNAc has been characterized and is now believed to
carry out both the initial 4,6-dehydratase reaction and
the subsequent epimerization of the resulting methyl
group at C-5. A phylogenetic tree of related sequences
shows a distinct clade of enzymes involved in the
biosynthesis of UDP-QuiNAc (Qui=qinovosamine). This
clade appears to be descendant from the common ancestor
of the Pseudomonas and E. coli fucose-biosynthesis
enzymes. It has been hypothesized that the first step in
the biosynthesis of these two compounds may be the same,
and thus that these enzymes all have the same function.
At present, lacking sufficient confirmation of this, the
current model trusted cutoff only covers the tree
segment surrounding the E. coli genes. The clades
containing the Pseudomonas and QuiNAc biosynthesis
enzymes score above the noise cutoff. Immediately below
the noise cutoff are enzymes involved in the
biosynthesis of UDP-RhaNAc (Rha=rhamnose), which again
may or may not produce the same product.

Putative catalytic domain, repeat 2, of uncharacterized
hypothetical proteins, which show high sequence homology
to the endonuclease from Salmonella typhimurium and
vertebrate phospholipase D6. Nuc and PLD6 belong to the
phospholipase D (PLD) superfamily. They contain a short
conserved sequence motif, the HKD motif (H-x-K-x(4)-D,
where x represents any amino acid residue), which
characterizes the PLD superfamily and is essential for
catalysis. Nuc and PLD6 utilize a two-step mechanism to
cleave phosphodiester bonds: Upon substrate binding, the
bond is first attacked by a histidine residue from one
HKD motif to form a covalent phosphohistidine
intermediate, which is then hydrolyzed by water with the
aid of a second histidine residue from the other HKD
motif in the opposite subunit. However, proteins in this
subfamily have two HKD motifs in a single polypeptide
chain.

human mitochondrial HSPA9 (also known as 70-kDa heat
shock protein 9, CSA; MOT; MOT2; GRP75; PBP74; GRP-75;
HSPA9B; MTHSP75; the gene encoding HSPA9 maps to
5q31.1), Escherichia coli DnaK, Saccharomyces cerevisiae

Ssc2p, Ssh1p, mtHSP70 homolog), and S. cerevisiae
Stress-Seventy subfamily C/Ssc1p (also called mtHSP70,
Endonuclease SceI 75 kDa subunit). It belongs to the
heat shock protein 70 (HSP70) family of chaperones that
assist in protein folding and assembly, and can direct
incompetent "client" proteins towards degradation.
Typically, HSP70s have a nucleotide-binding domain (NBD)
and a substrate-binding domain (SBD). The nucleotide
sits in a deep cleft formed between the two lobes of the
NBD. The two subdomains of each lobe change conformation
between ATP-bound, ADP-bound, and nucleotide-free
states. ATP binding opens up the substrate-binding site;
substrate-binding increases the rate of ATP hydrolysis.
Hsp70 chaperone activity is regulated by various
co-chaperones: J-domain proteins and nucleotide exchange
factors (NEFs); for Escherichia coli DnaK, these are the
DnaJ and GrpE, respectively.
