Is predicted to encode a protein with the following domains: Ubiquitin-conjugating enzyme E2; Ubiquitin-conjugating enzyme/RWD-like; Ubiquitin-conjugating enzyme; WD40-repeat-containing domain superfamily; and Ribosomal RNA-processing protein Rrp9-like. Is an ortholog of C. elegans ubc-16. In C. elegans, ubc-16 is involved in protein ubiquitination.
