ACP1 is part of the phosphotyrosine protein. ACP1 functions as an acid phosphatase and a protein tyrosine phosphatase (PTPase) existing in all human tissues, including adipocytes. ACP1 enzyme hydrolyzes protein tyrosine phosphate to protein tyrosine and orthophosphate, and also orthophosphoric monoesters to alcohol and orthophosphate. ACP1 is present in adipocytes, thus playing a specific role in the regulation of adipose tissue. High levels of the ACP1 negatively regulate cell proliferation and growth of leiomyomas during dephosphorylation of the PDGF receptor. High significant differences in birth weight-placental weight relationships were observed among acid phosphatase locus 1 phenotypes.
Recombinant Human ACP1 produced in E.Coli is a single, non-glycosylated polypeptide chain containing 178 amino acids (1-158 a.a.) and having a molecular mass of 20.1 kDa. ACP1 is fused to a 20 amino acid His-Tag at N-Terminus and purified by conventional chromatography techniques.
