In humans it is encoded by the PTPN1 gene. PTP1B is a negative regulator of the insulin signaling pathway and … Visa mer PTP1B was first isolated from a human placental protein extract, but it is expressed in many tissues. PTP1B is localized to the cytoplasmic face of the endoplasmic reticulum. PTP1B can dephosphorylate the … Visa mer The Cys215 residue is essential for the enzymatic activity of PTP1B and similar cysteine residues are required for the activity of other members of the Class I PTP family. … Visa mer PTP1B has clinical implications in the treatment of type 2 diabetes as well as cancer. Gene knockout studies conducted in murine models has provided substantial evidence for the role … Visa mer The phosphatase activity of PTP1B occurs via a two-step mechanism. The dephosphorylation of the pTyr substrate occurs in the first step, while the enzyme intermediates are broken down during the second step. During the first step, there is a nucleophilic attack … Visa mer PTPN1 has been shown to interact with BCAR1, epidermal growth factor receptor, Grb2 and IRS1.
