Background: LMW-PTP/ACP1

Low molecular weight protein tyrosine phosphatase (LMW-PTP), also known as Acid Phosphatase 1 (ACP1), is an 18 kDa cytosolic phosphatase that is unrelated to other tyrosine phosphatases, such as PTP1B. Tyrosine phosphorylation of LMW-PTP increases its activity 20-fold and affects its ability to dephosphorylate targets such as the PDGF receptor. Cancer cells overexpressing LMW-PTP have a higher proliferative rate and generate tumors that are larger than untransfected controls. Colon adenocarcinomas induced by dimethylhydrazine also have elevated levels of LMW-PTP, suggesting that this phosphatase may be a marker for oncogenic transformation. Human LMW-PTP shares 86% and 87% amino acid sequence identity with mouse and rat LMW-PTP, respectively.
