CRYSTAL STRUCTURE of PROTEIN TYROSINE PHOSPHATASE 1B IN COMPLEX WITH AN INHIBITOR [(4-{(2S)-2-(1,3-BENZOXAZOL-2-YL)-2-[(4-FLUOROPHENYL)SULFAMOYL]ETHYL}PHENYL)AMINO](OXO)ACETIC ACID

Template:ABSTRACT PUBMED 23964742

Function

[PTN1_HUMAN] 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.[1] [2]
