Carboxyl-terminal PDZ ligand of neuronal nitric oxide synthase protein (CAPON) ...
 2-185 4.55e-124

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.

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.

 30-174 1.31e-16

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.

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.

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.

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.

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.
