Invitrogen™ Phospho-PTP1B (Ser50) Polyclonal Antibody

Rabbit Polyclonal Antibody

Brand:  Invitrogen™ PA5143754

Product Code. 17896768

Description

The antibody detects a 50 kDa* doublet corresponding to PTP1B in western blots of calyculin A treated human A431 and Jurkat cells. This reactivity is observed as a weak singlet in control cells and is not observed after lambda phosphatase treatment.

PTP1B (PTPN1) is a tyrosine-protein phosphatase which acts as a regulator of endoplasmic reticulum unfolded protein response. It mediates dephosphorylation of EIF2AK3/PERK and in turn inactivates the protein kinase activity of EIF2AK3/PERK. PTP1B also plays a role in CKII- and p60c-src-induced signal transduction cascades. It regulates the EFNA5-EPHA3 signaling pathway which modulates cell reorganization and cell-cell repulsion. PTP1B also regulates the hepatocyte growth factor receptor signaling pathway through dephosphorylation of MET.
