Is predicted to encode a protein with the following domains: Bap31/Bap29 cytoplasmic coiled-coil domain; Ubiquitin-conjugating enzyme/RWD-like; ARMET, C-terminal; Ubiquitin-conjugating enzyme; SAP domain superfamily; BAP29/BAP31, transmembrane domain; Ubiquitin-conjugating enzyme E2; and Bap31/Bap29 transmembrane region. Is an ortholog of C. elegans
ubc-13. In C. elegans,
ubc-13 is involved in protein ubiquitination and regulation of protein localization to cell surface.
