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