|---|---|
| Alternative Names | 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 | A phospho-specific peptide corresponding to residues surrounding serine 378 of human PTP1B was used as an immunogen. This antibody detects PTP1B phosphorylated on serine 378. |
| Cellular Localization | Endoplasmic reticulum membrane; Peripheral membrane protein; Cytoplasmic side. Note=Interacts with EPHA3 at the cell membrane |
| Entrez Gene | 5770 |
