Summaries for ACP1 Gene

Entrez Gene Summary for ACP1 Gene

  • The product of this gene belongs to the phosphotyrosine protein phosphatase family of proteins. It functions as an acid phosphatase and a protein tyrosine phosphatase by hydrolyzing protein tyrosine phosphate to protein tyrosine and orthophosphate. This enzyme also hydrolyzes orthophosphoric monoesters to alcohol and orthophosphate. This gene is genetically polymorphic, and three common alleles segregating at the corresponding locus give rise to six phenotypes. Each allele appears to encode at least two electrophoretically different isozymes, Bf and Bs, which are produced in allele-specific ratios. Multiple alternatively spliced transcript variants encoding distinct isoforms have been identified for this gene. [provided by RefSeq, Aug 2008]

Polymorphic Variants from UniProtKB/Swiss-Prot for ACP1 Gene

ACP1 is genetically polymorphic. Three common alleles are known in Caucasians: ACP1*A, ACP1*B and ACP1*C. They give rise to six different phenotypes. Each allele appears to encode two electrophoretically different isozymes, F and S, which are produced in allele-specific ratios (PubMed:1939112). The sequence shown is that of allele ACP1*B and allele ACP1*C.
