Ankyrin repeat and sterile alpha motif (SAM) domain-containing (Anks) protein family ...
 1-126 1.03e-85

Ankyrin repeat and sterile alpha motif (SAM) domain-containing (Anks) protein family Phosphotyrosine-binding (PTB) domain; Both AIDA-1b (AbetaPP intracellular domain-associated protein 1b) and Odin (also known as ankyrin repeat and sterile alpha motif domain-containing 1A; ANKS1A) belong to the Anks protein family. Both of these family members interacts with the EphA8 receptor. Ank members consists of ankyrin repeats, a SAM domain and a C-terminal PTB domain which is crucial for interaction with the juxtamembrane (JM) region of EphA8. PTB domains are classified into three groups, namely, phosphotyrosine-dependent Shc-like, phosphotyrosine-dependent IRS-like, and phosphotyrosine-independent Dab-like PTB domains of which the Anks PTB is a member. 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.

Cell death protein 6 homolog (CED-6/GULP1) Phosphotyrosine-binding (PTB) domain; CED6 (also known as GULP1: engulfment adaptor PTB domain containing 1) is an adaptor protein involved in the specific recognition and engulfment of apoptotic cells. CED6 has been shown to interact with the cytoplasmic tail of another protein involved in the engulfment of apoptotic cells, CED1. CED6 has a C-terminal PTB domain, which can bind to NPXY motifs. 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.

 4-118 1.92e-12

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 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.

 1-114 9.04e-11

Low Density Lipoprotein Receptor Adaptor Protein 1 (LDLRAP1) in mammals and similar proteins Phosphotyrosine-binding (PTB) PH-like fold; The null mutations in the LDL receptor adaptor protein 1 (LDLRAP1) gene, which serves as an adaptor for LDLR endocytosis in the liver, causes autosomal recessive hypercholesterolemia (ARH). LDLRAP1 contains 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 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 contains mammals, insects, and sponges.

 31-128 1.30e-09

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 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.

 5-96 2.38e-09

Numb Phosphotyrosine-binding (PTB) domain; Numb is a membrane associated adaptor protein which plays critical roles in cell fate determination. Numb proteins are involved in control of asymmetric cell division and cell fate choice, endocytosis, cell adhesion, cell migration, ubiquitination of specific substrates and a number of signaling pathways (Notch, Hedgehog, p53). Mutations in Numb plays a critical role in disease (cancer). Numb has an N-terminal PTB domain and a C-terminal NumbF 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.

 24-117 3.58e-09

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.

 7-119 3.07e-08

Disabled (Dab) Phosphotyrosine-binding domain; Dab is a cystosolic adaptor protein, which binds to the cytoplasmic tails of lipoprotein receptors, such as ApoER2 and VLDLR, via its PTB domain. The dab PTB domain has a preference for unphosphorylated tyrosine within an NPxY motif. Additionally, the Dab PTB domain, which is structurally similar to PH domains, binds to phosphatidlyinositol phosphate 4,5 bisphosphate in a manner characteristic of phosphoinositide binding PH domains. 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.

uncharacterized protein LOC417372 Phosphotyrosine-binding (PTB) PH-like fold; The function of LOC417372 and its related proteins are unknown to date. Members here contain a N-terminal RUN domain, followed by a PDZ domain, and a C-terminal PTB domain. The RUN domain is involved in Ras-like GTPase signaling. The PDZ domain (also called DHR/Dlg homologous region or GLGF after its conserved sequence motif) binds C-terminal polypeptides, internal (non-C-terminal) polypeptides, and lipids. PTB domains have a common PH-like fold and are found in various eukaryotic signaling molecules.

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.
