Is predicted to encode a protein with the following domains: EARP and GARP complex-interacting protein 1; WD40/YVTN repeat-like-containing domain superfamily; WD40 repeat; WD domain, G-beta repeat; and WD40-repeat-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.
