Is predicted to encode a protein with the following domains: Beige/BEACH domain; BEACH domain; PH-BEACH domain; Armadillo-type fold; Neurobeachin-like, DUF1088; Neurobeachin/BDCP, DUF4704 alpha solenoid region; WD40 repeat; PH domain associated with Beige/BEACH; Concanavalin A-like lectin/glucanases superfamily; Neurobeachin/BDCP, DUF4704; Concanavalin A-like lectin/glucanase domain superfamily; BEACH domain superfamily; WD domain, G-beta repeat; and WD40-repeat-containing domain superfamily. 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.
