== Publication Abstract from PubMed ==

Proteins containing ubiquitin-like (UBL) and ubiquitin-associated (UBA) domains interact with various binding partners and function as hubs during ubiquitin-mediated protein degradation. A common interaction of the budding yeast UBL-UBA proteins Rad23 and Dsk2 with the E4 ubiquitin ligase Ufd2 has been described in endoplasmic reticulum-associated degradation among other pathways. The UBL domains of Rad23 and Dsk2 play a prominent role in this process by interacting with Ufd2 and different subunits of the 26 S proteasome. Here, we report crystal structures of Ufd2 in complex with the UBL domains of Rad23 and Dsk2. The N-terminal UBL-interacting region of Ufd2 exhibits a unique sequence pattern, which is distinct from any known ubiquitin- or UBL-binding domain identified so far. Residue-specific differences exist in the interactions of these UBL domains with Ufd2, which are coupled to subtle differences in their binding affinities. The molecular details of their differential interactions point to a role for adaptive evolution in shaping these interfaces.

The yeast E4 ubiquitin ligase Ufd2 interacts with the ubiquitin-like domains of Rad23 and Dsk2 via a novel and distinct ubiquitin-like binding domain.,Hanzelmann P, Stingele J, Hofmann K, Schindelin H, Raasi S J Biol Chem. 2010 Jun 25;285(26):20390-8.

[[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>
