Is predicted to encode a protein with the following domains: Domain of unknown function DUF3447; Ankyrin repeats (3 copies); Ankyrin repeat; Ankyrin repeat-containing domain superfamily; and Tetratricopeptide-like helical domain superfamily. Is an ortholog of C. elegans fem-1. In C. elegans, fem-1 is involved in several processes, including proteasome-mediated ubiquitin-dependent protein catabolic process; regulation of germ cell proliferation; and sex determination.
