Tyrosine-protein phosphatase, non-receptor type 1 (PTP1B) also know as Protein-tyrosine phosphatase 1B, PTPN1 is a PTP (protein tyrosine phosphatase) first isolated from human placenta. The protein is unrelated to other known phosphatases but is similar to common leukocyte antigen (CD45) and to LAR a homolog of the neural adhesion molecule NCAM. PTP1B negatively regulates insulin sensitivity by dephosphorylating the insulin receptor. Akt is a ser/thr kinase effector of insulin signaling that phosphorylates substrates at the consensus motif RXRXXS/T. PTP1B contains the Akt phosphorylation motif (RYRDVS50), and PTP1B (but not mutants with substitutions for Ser50) are phosphorylated by Akt. Insulin stimulation also causes a significant increase in phosphorylation of PTP1B.
