LMW-PTP (Low Molecular Weight Protein Tyrosine Phosphatase; also Red cell acid phosphatase 1/ACP1, HCPTP, and HAAP/Adipocyte acid phosphatase) is a 17‑18 kDa member of the LMWPTP family, PTP superfamily of enzymes. It is widely expressed, being found in cells diverse as B and T cells, endothelial cells and vascular smooth muscle cells. LMW-PTP dephosphorylates multiple substrates, often in a cell-dependent manner. Among the substrates for LMW-PTP include PDGR beta, EphA2 and beta -catenin. PMW-PTP is found intracellularly, generally associated with two cytoplasmic pools, one in the cytosol and the other accompaning the cytoskeleton. Human LMW-PTP is 158 amino acids (aa) in length. The catalytic region spans aa 9-154, and there are two acetylation sites at Ala2 and Lys156. Phosphorylation on Tyr132 and Tyr133 occurs on cytoskeleton-associated LMW-PTP, and has the effect of increasing its phosphatase activity. There are three alternative splice variants reported for LMW-PTP. One shows a 34 aa substitution for aa 41-74, a second shows a deletion of aa 41-74, while a third contains a 35 aa substitution for aa 78-158. The last two isoforms may function a negative regulators of LMW-PTP activity. Full-length LMW-PTP shares 86% aa sequence identity with mouse LMW-PTP.
