Is predicted to encode a protein with the following domains: Myotubularin-like phosphatase domain; GRAM domain; Protein-tyrosine phosphatase-like; Myotubularin family; Protein-tyrosine phosphatase, catalytic; and PH-like domain superfamily. Is an ortholog of C. elegans mtm-1. In C. elegans, mtm-1 is involved in negative regulation of engulfment of apoptotic cell and phospholipid dephosphorylation.
