Is predicted to encode a protein with the following domains: Dual specificity protein phosphatase domain; Protein-tyrosine phosphatase-like; and Dual specificity phosphatase, catalytic domain. Is an ortholog of C. elegans vhp-1. In C. elegans, vhp-1 is involved in several processes, including negative regulation of MAPK cascade; regulation of defense response to bacterium; and regulation of protein localization to nucleus.
