Is predicted to encode a protein with the following domains: WD domain, G-beta repeat; WD40 repeat; EARP and GARP complex-interacting protein 1; and WD40/YVTN repeat-like-containing domain superfamily. Is an ortholog of C. elegans eipr-1. In C. elegans, eipr-1 is involved in positive regulation of dense core granule transport; positive regulation of egg-laying behavior; and positive regulation of locomotion involved in locomotory behavior.
