Is predicted to encode a protein with the following domains: PFU (PLAA family ubiquitin binding); PUL domain; Armadillo-like helical; WD domain, G-beta repeat; PLAA family ubiquitin binding domain; WD40 repeat; WD40/YVTN repeat-like-containing domain superfamily; PFU domain superfamily; and WD40-repeat-containing domain superfamily. Is an ortholog of C. elegans ufd-3.
