Is predicted to encode a protein with the following domains: Ankyrin repeat and LEM domain-containing protein 2; Zinc finger, HIT-type; Ankyrin repeat-containing domain superfamily; Ankyrin repeats (many copies); HIT zinc finger; and Ankyrin repeat. Is an ortholog of C. elegans lem-4. In C. elegans, lem-4 is involved in mitotic nuclear membrane reassembly and negative regulation of phosphorylation.
