PTPRK (Receptor-type tyrosine-protein phosphatase kappa) is an enzyme. The public catalogues list it as an oncogene driver and a tumour suppressor, and it is called a cancer driver by mutation analysis of patient cohorts. Tied to Breast cancer, Bladder & urothelial cancer, Renal cell carcinoma and 5 more. This dossier gathers the 0 products (0 approved), 0 trials, 0 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.

Biology

Regulation of processes involving cell contact and adhesion such as growth control, tumour invasion, and metastasis. Negative regulator of EGFR signalling pathway. Forms complexes with beta-catenin and gamma-catenin/plakoglobin. Beta-catenin may be a substrate for the catalytic activity of PTPRK/PTP-kappa. Location: Cell junction, adherens junction; Cell membrane (UniProt). Locus 6q22.33 (HGNC).
