Is predicted to encode a protein with the following domains: Ubiquitin-like domain superfamily; UBA-like domain; UBX domain; Thioredoxin-like superfamily; and UAS. Is an ortholog of C. elegans ubxn-3. In C. elegans, ubxn-3 is involved in several processes, including developmental process involved in reproduction; positive regulation of mitotic cell cycle, embryonic; and regulation of protein localization to chromatin.
