Name Receptor-type tyrosine-protein phosphatase kappa
Description Not Available
Synonyms
  1. Protein-tyrosine phosphatase kappa
  2. R-PTP-kappa
  3. SubName: Protein tyrosine phosphatase, receptor type, K
Gene Name PTPRK
Protein Type Enzyme
Biological Properties
General Function Involved in phosphatase activity
Specific Function Regulation of processes involving cell contact and adhesion such as growth control, tumor invasion, and metastasis. Negative regulator of EGFR signaling pathway. Forms complexes with beta-catenin and gamma-catenin/plakoglobin. Beta-catenin may be a substrate for the catalytic activity of PTPRK/PTP-kappa.
