Is predicted to encode a protein with the following domains: BRO1 domain superfamily; ALIX V-shaped domain; ALIX V-shaped domain binding to HIV; BRO1-like domain; and BRO1 domain. Is an ortholog of C. elegans ego-2. In C. elegans, ego-2 is involved in positive regulation of Notch signaling pathway and protein localization to basolateral plasma membrane.
