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