Is predicted to encode a protein with the following domains: Zinc finger, C3HC4 type (RING finger); Ankyrin repeats (3 copies); Myotubularin-like phosphatase domain; Ankyrin repeat; Protein-tyrosine phosphatase, catalytic; Myotubularin-like phosphatase domain; PH-like domain superfamily; Zinc finger, RING/FYVE/PHD-type; Ankyrin repeat-containing domain; Protein-tyrosine phosphatase-like; S-adenosyl-L-methionine-dependent methyltransferase; Myotubularin family; and Ankyrin repeat-containing domain superfamily. Is an ortholog of C. elegans F22B7.9; mib-1
; and mtm-1
. In C. elegans, mtm-1
is involved in negative regulation of engulfment of apoptotic cell and phospholipid dephosphorylation.
