Is predicted to encode a protein with the following domains: BEACH domain superfamily; Beige/BEACH domain; BEACH domain; WD domain, G-beta repeat; WD40 repeat; WD40/YVTN repeat-like-containing domain superfamily; and WD40-repeat-containing domain superfamily. Is an ortholog of C. elegans sorf-2. In C. elegans, sorf-2 is involved in endosomal transport; organelle fusion; and positive regulation of early endosome to late endosome transport.
