Is predicted to encode a protein with the following domains: WD40/YVTN repeat-like-containing domain superfamily; WD40 repeat; Tetratricopeptide-like helical domain superfamily; and WD40-repeat-containing domain superfamily. Is an ortholog of C. elegans osm-1. In C. elegans, osm-1 is involved in dauer entry and non-motile cilium assembly.
