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