Background
| Function | 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. {ECO:0000269|PubMed:19836242}. |
| Pathway | |
| Protein Families | Protein-tyrosine phosphatase family, Receptor class 2B subfamily |
| Tissue Specificity | High levels in lung, brain and colon; less in liver, pancreas, stomach, kidney, placenta and mammary carcinoma. |
