Gene Summary

[ - ] NCBI Entrez Gene

Gene ID 52 Official Symbol ACP1
Locus N/A Gene Type protein-coding
Synonyms HAAP; MGC111030; MGC3499
Full Name acid phosphatase 1, soluble
Description acid phosphatase 1, soluble
Chromosome 2p25
Also Known As acid phosphatase of erythrocyte; adipocyte acid phosphatase; cytoplasmic phosphotyrosyl protein phosphatase; low molecular weight phosphotyrosine protein phosphatase; protein tyrosine phosphatase; red cell acid phosphatase 1
Summary 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]
