for Recombinant PTPN1 (1-321) proteinBackground

PTPN1 (protein tyrosine phosphatase, non-receptor type 1, also known as PTP1B) is a member of the protein tyrosine phosphatase (PTP) family. PTPs catalyze the hydrolysis of the phosphate monoesters specifically on tyrosine residues. Members of the PTP family have a highly conserved catalytic motif, which is essential for the catalytic activity. PTPs regulate a variety of cellular processes including cell growth, differentiation, mitotic cycle, and oncogenic transformation as signaling molecules. Epidermal growth factor receptor (EGFR) and the adaptor protein Shc were reported to be substrates of this PTP, which suggested the roles in growth factor mediated cell signaling. PTPN1 acts as a negative regulator of insulin signaling by dephosphorylating the phosphotryosine residues of insulin receptor kinase. PTPN1 dephosphorylates epidermal growth factor receptor kinase, as well as JAK2 and TYK2 kinases.
