Is predicted to encode a protein with the following domains: WD40/YVTN repeat-like-containing domain superfamily; WD domain, G-beta repeat; WD40-repeat-containing domain superfamily; and WD40 repeat. Is an ortholog of C. elegans sel-2. In C. elegans, sel-2 is involved in several processes, including apical protein localization; negative regulation of Notch signaling pathway; and regulation of vulval development.
