Subcellular Location:
Cytoplasm.

Function

Function:
Acts on tyrosine phosphorylated proteins, low-MW aryl phosphates and natural and synthetic acyl phosphates. Isoform 3 does not possess phosphatase activity.
Catalytic Activity:
Protein tyrosine phosphate + H(2)O = protein tyrosine + phosphate.; A phosphate monoester + H(2)O = an alcohol + phosphate.
Enzyme Regulation:
ENZYME REGULATION: Inhibited by sulfhydryl reagents.
Active Site:
ACT_SITE 13 13 Nucleophile.
