Is predicted to encode a protein with the following domains: Anaphase-promoting complex subunit 4, WD40 domain; Anaphase-promoting complex subunit 4 WD40 domain; Vacuolar protein sorting-associated protein 8, central domain; Golgi CORVET complex core vacuolar protein 8; WD40-repeat-containing domain superfamily; and WD40/YVTN repeat-like-containing domain superfamily. Is an ortholog of C. elegans vps-8.
