PTP kappa Antibody (N-term) Blocking peptide

Peptides; Blocking Peptides

PTPkappa, a member of the receptor class 2B subfamily of protein-tyrosine phophatases, is involved in regulation of processes involving cell contact and adhesion such as growth control, tumor invasion, and metastasis. It forms complexes with beta-catenin and gamma-catenin/plakoglobin. Beta-catenin may be a substrate for the catalytic activity of PTP-kappa. This Type I membrane protein, localized at adherens junctions, is found at high levels in lung, brain and colon; less in liver, pancreas, stomach, kidney, placenta and mammary carcinoma. It contains 4 fibronectin type III domains, 1 immunoglobulin-like C2-type domain, 1 MAM domain, and 2 protein-tyrosine phosphatase domains.
