Is predicted to encode a protein with the following domains: WD domain, G-beta repeat; WD40 repeat; WD40-repeat-containing domain superfamily; G-protein beta WD-40 repeat; WD40/YVTN repeat-like-containing domain superfamily; and G-protein, beta subunit. Is an ortholog of C. elegans
gpb-1. In C. elegans,
gpb-1 is involved in several processes, including establishment of mitotic spindle orientation; negative regulation of locomotion; and regulation of egg-laying behavior.
