Is predicted to encode a protein with the following domains: Myotubularin-like phosphatase domain; Protein-tyrosine phosphatase-like; PH-like domain superfamily; Protein-tyrosine phosphatase, catalytic; Myotubularin family; and GRAM domain. 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.
