Protein-tyrosine phosphatase 1B

Basic Info

Synonyms
非受体1型蛋白酪氨酸磷酸酶, protein tyrosine phosphatase non-receptor type 1, Protein-tyrosine phosphatase 1B
+ [4]
Introduction
Tyrosine-protein phosphatase which acts as a regulator of endoplasmic reticulum unfolded protein response. Mediates dephosphorylation of EIF2AK3/PERK; inactivating the protein kinase activity of EIF2AK3/PERK. May play an important role in CKII- and p60c-src-induced signal transduction cascades. May regulate the EFNA5-EPHA3 signaling pathway which modulates cell reorganization and cell-cell repulsion. May also regulate the hepatocyte growth factor receptor signaling pathway through dephosphorylation of MET.
