[[http://www.uniprot.org/uniprot/UFD2_YEAST UFD2_YEAST]] E4 ubiquitin chain-elongation enzyme specifically involved in polyubiquitin chain assembly. Binds to CDC48 and elongates mono- and diubiquitinated ERAD substrates presented by the UFD1-NPL4-CDC48/p97 (UNC) AAA ATPase complex to a chain length of 4 to 6 ubiquitin moieties. Delivers these polyubiquitinated substrates to RAD23 and DSK2, which target them to the proteasome. Has E3 ubiquitin-protein ligase activity, accepting ubiquitin from its cognate E2 ubiquitin-conjugating enzyme UBC4. Enhances ubiquitination at 'Lys-48', but not at 'Lys-29' of the Ub moiety. Promotes ubiquitin chain elongation at 'Lys-48' on the DOA10 substrate PEX29. Also involved in the proteolytic processing of the ER-bound transcription factor SPT23.<ref>PMID:10089879</ref> <ref>PMID:15240124</ref> <ref>PMID:15652483</ref> <ref>PMID:18191224</ref> <ref>PMID:20159987</ref>
