PTP rho/PTPRT: Lysates

Protein Tyrosine Phosphatase, Receptor-type T (PTPRT), also known as RPTPrho, dephosphorylates tyrosine residues in proteins. PTPRT is present in many tissues, including brain, heart, lung, and colon. Genetic screening of colon cancers indicates that the PTPRT gene has a high incidence of missense mutations that reduce phosphatase activity in the encoded protein. Overexpression of intact PTPRT in cancer cell lines inhibits cell proliferation, suggesting that the phosphatase is a tumor suppressor.
