Name Tyrosine-protein phosphatase non-receptor type 1
Description Not Available
Synonyms
  1. PTP-1B
  2. Protein-tyrosine phosphatase 1B
Gene Name PTPN1
Protein Type Enzyme
Biological Properties
General Function Involved in phosphatase activity
Specific Function 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.
