Protein

Tyrosine-protein phosphatase non-receptor type 1

Gene

Ptpn1

Organism
Rattus norvegicus (Rat)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

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 (By similarity).By similarity

Catalytic activityi

Protein tyrosine phosphate + H2O = protein tyrosine + phosphate.PROSITE-ProRule annotation
