>gnl|CDD|241301 cd01271, PTB2_Fe65, Fe65 C-terminal Phosphotyrosine-binding (PTB)
domain. The neuronal adaptor protein Fe65 is involved
in brain development, Alzheimer disease amyloid
precursor protein (APP) signaling, and proteolytic
processing of APP. It contains three protein-protein
interaction domains, one WW domain, and a unique tandem
array of phosphotyrosine-binding (PTB) domains. The
C-terminal PTB domain is responsible for APP binding.
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.

(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
domains, which recognize phosphotyrosine and adjacent
carboxy-terminal residues, PTB-domain binding
specificity is conferred by residues amino-terminal to

three groups: phosphotyrosine-dependent Shc-like,
phosphotyrosine-dependent IRS-like, and
phosphotyrosine-independent Dab-like PTB domains. This

Rab5, GIPC (GAIP-interacting protein, C terminus), human

>gnl|CDD|241311 cd13157, PTB_tensin-related, Tensin-related Phosphotyrosine-binding
(PTB) domain. Tensin plays critical roles in renal
function, muscle regeneration, and cell migration. It
binds to actin filaments and interacts with the
cytoplasmic tails of beta-integrin via its PTB domain,
allowing tensin to link actin filaments to integrin
receptors. Tensin functions as a platform for assembly
and disassembly of signaling complexes at focal
adhesions by recruiting tyrosine-phosphorylated
signaling molecules, and also by providing interaction
sites for other proteins. In addition to its PTB
domain, it contains a C-terminal SH2 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.

Shc is a substrate for receptor tyrosine kinases, which
can interact with phosphoproteins at NPXY motifs. Shc
contains an PTB domain followed by an SH2 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

>gnl|CDD|241300 cd01270, PTB_CAPON-like, Carboxyl-terminal PDZ ligand of neuronal
nitric oxide synthase protein (CAPON)
Phosphotyrosine-binding (PTB) domain. CAPON (also known
as Nitric oxide synthase 1 adaptor protein, NOS1AP,
encodes a cytosolic protein that binds to the signaling
molecule, neuronal NOS (nNOS). It contains a N-terminal
PTB domain that binds to the small monomeric G protein,
Dexras1 and a C-terminal PDZ-binding domain that
mediates interactions with nNOS. Included in this cd
are C. elegan proteins dystrobrevin, DYB-1, which
controls neurotransmitter release and muscle Ca(2+)
transients by localizing BK channels and DYstrophin-like
phenotype and CAPON related,DYC-1, which is functionally
related to dystrophin homolog, DYS-1. Mutations in the
dystrophin gene causes Duchenne muscular dystrophy.
DYS-1 shares sequence similarity, including key motifs,
with their mammalian counterparts. These CAPON-like
proteins all have a single 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

>gnl|CDD|234536 TIGR04312, choice_anch_B, choice-of-anchor B domain. This domain,
about 385 amino acids long, can have either of at least
two types of C-terminal sorting signal. Members from
Shewanella and allies have the rhombosortase target
domain GlyGly-CTERM (TIGR03501), while members of the
Bacteroidetes have the Por secretion system C-terminal
domain (TIGR04183). Most other members lack any
C-terminal extension, but in most of those, the normal
signal sequence is replaced by a lipoprotein signal
sequence. Member sequences show a region of local
similarity to the LVIVD repeat sequence (pfam08309).
