Is predicted to encode a protein with the following domains: Ubiquitin-like domain superfamily; NSFL1 cofactor p47, SEP domain superfamily; SEP domain; and UBX domain. Is an ortholog of C. elegans ubxn-2. In C. elegans, ubxn-2 is involved in several processes, including developmental process involved in reproduction; establishment of mitotic spindle orientation; and negative regulation of protein localization to centrosome.
