Rabbit anti-Human Phospho-PTPRA-Y789 Polyclonal Antibody

Uniprot Id

P18433

Target Species

Human

Target Name

PTPRA

Target Full Name

Receptor-type tyrosine-protein phosphatase alpha

Target Function

Tyrosine protein phosphatase which is involved in integrin-mediated focal adhesion formation. Following integrin engagement, specifically recruits BCAR3, BCAR1 and CRK to focal adhesions thereby promoting SRC-mediated phosphorylation of BRAC1 and the subsequent activation of PAK and small GTPase RAC1 and CDC42.

Target Subcellular Location

Cell membrane; Single-pass type I membrane protein. Cell junction, focal adhesion.

Target Protein Families

Protein-tyrosine phosphatase family, Receptor class 4 subfamily

Target Synonyms

PTPRA; PTPA; PTPRL2; Receptor-type tyrosine-protein phosphatase alpha; Protein-tyrosine phosphatase alpha; R-PTP-alpha

Target Background

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 contains an extracellular domain, a single transmembrane segment and two tandem intracytoplasmic catalytic domains, and thus represents a receptor-type PTP. This PTP has been shown to dephosphorylate and activate Src family tyrosine kinases, and is implicated in the regulation of integrin signaling, cell adhesion and proliferation. Three alternatively spliced variants of this gene, which encode two distinct isoforms, have been reported.
