Target Information
PTP1B (PTPN1) is a tyrosine-protein phosphatase that regulates the endoplasmic reticulum unfolded protein response by dephosphorylating EIF2AK3/PERK, thereby inactivating its kinase activity. It participates in CKII- and p60c-src-induced signaling cascades and modulates EFNA5-EPHA3 signaling, influencing cell organization and repulsion. PTP1B also regulates hepatocyte growth factor receptor (MET) signaling through dephosphorylation.
