PTPN1 PTP1B Tyrosine-protein phosphatase non-receptor type 1 Protein-tyrosine phosphatase 1B
Molecular Weight(MW)
49967 Da
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
Tissue Specificity
This PTP1B antibody is generated from rabbits immunized with a peptide from the N-terminal part of human PTP1B.
Cellular Localization
Endoplasmic reticulum membrane; Peripheral membrane protein; Cytoplasmic side. Note=Interacts with EPHA3 at the cell membrane
