Description

Application Note: Kinase assay Recombinant human PTPN13 (2169-2485) was expressed in E.coli cells using a N-terminal GST tag.

Function: Regulates negatively FAS-induced apoptosis and NGFR-mediated pro-apoptotic signaling.

Catalytic Activity: Protein tyrosine phosphate + H2O = protein tyrosine + phosphate.

Subunit: Interacts with TRIP6 and TNFRSF6 (Fas receptor) through its second PDZ domain. Interacts with the C-terminal SVP motif of NGFR through its third PDZ domain. Interacts with the LIM domain of PDLIM4 through its second and fourth PDZ domains. Binds PLEKHA1 and PLEKHA2 through its first PDZ domain. Interacts with BRD7.

Subcellular Location: Cytoplasm (By similarity).

Tissue Specificity: Present in most tissues with the exception of the liver and skeletal muscle. Most abundant in lung, kidney and fetal brain.

Similarity: Belongs to the protein-tyrosine phosphatase family. Non-receptor class subfamily.

Similarity: Contains 1 FERM domain.

Similarity: Contains 5 PDZ (DHR) domains.

Similarity: Contains 1 tyrosine-protein phosphatase domain.

Summary: The protein encoded by this gene is a member of the protein tyrosine phosphatase (PTP) family. PTPs are known to be signaling molecules that regulate a variety of cellular processes including cell growth, differentiation, mitotic cycle, and oncogenic transformation. This PTP is a large protein that possesses a PTP domain at C-terminus, and multiple noncatalytic domains, which include a domain with similarity to band 4.1 superfamily of cytoskeletal-associated proteins, a region consisting of five PDZ domains, and a leucine zipper motif. This PTP was found to interact with, and dephosphorylate Fas receptor, as well as IkappaBalpha through the PDZ domains, which suggested its role in Fas mediated programmed cell death. This PTP was also shown to interact with GTPase-activating protein, and thus may function as a regulator of Rho signaling pathway. Four alternatively spliced transcript variants, which encode distinct proteins, have been reported.
