A non-specific tyrosine phosphatase that dephosphorylates a diverse number of substrates under acidic conditions (pH 4-6) including alkyl, aryl, and acyl orthophosphate monoesters and phosphorylated proteins. Has lipid phosphatase activity and inactivates lysophosphatidic acid in seminal plasma. Belongs to the histidine acid phosphatase family. 2 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
