PTPN12 Protein, Human

PTPN12 Protein, a versatile enzyme, dephosphorylates various proteins, regulating cellular signaling cascades. Documented in literature, PTPN12 selectively targets tyrosine kinases like ERBB2 and PTK2B/PYK2, exerting control over associated pathways. Notably, PTPN12's specificity is evident in dephosphorylating ERBB2 at specific tyrosine residues, such as 'Tyr-1112,' 'Tyr-1196,' and/or 'Tyr-1248.' Its intricate dephosphorylation activity underscores PTPN12's significance in modulating key signaling events and fine-tuning cellular responses within tyrosine kinase pathways. PTPN12 Protein, Human is the recombinant human-derived PTPN12 protein, expressed by Sf9 insect cells , with tag free. and with residual Gly-Pro in N-terminal (not related to functional changes) mutation. The total length of PTPN12 Protein, Human is 355 a.a., with molecular weight of ~41 kDa.

PTPN12 Protein, the subject, functions as a versatile enzyme capable of dephosphorylating a range of proteins, thereby playing a crucial role in the regulation of various cellular signaling cascades, as documented in the literature. Among its substrates, PTPN12 selectively dephosphorylates cellular tyrosine kinases, including ERBB2 and PTK2B/PYK2, exerting regulatory control over signaling pathways involving these kinases. The specificity of PTPN12 is highlighted by its ability to dephosphorylate ERBB2 at specific tyrosine residues, such as 'Tyr-1112,' 'Tyr-1196,' and/or 'Tyr-1248.' The intricate dephosphorylation activity of PTPN12 underscores its significance in modulating key signaling events and fine-tuning cellular responses mediated by tyrosine kinase pathways.
