== Publication Abstract from PubMed ==
EDD (or HYD) is an E3 ubiquitin ligase in the family of HECT (homologous to E6-AP C terminus) ligases. EDD contains an N-terminal ubiquitin-associated (UBA) domain, which is present in a variety of proteins involved in ubiquitin-mediated processes. Here, we use isothermal titration calorimetry (ITC), NMR titrations, and pull-down assays to show that the EDD UBA domain binds ubiquitin. The 1.85 A crystal structure of the complex with ubiquitin reveals the structural basis of ubiquitin recognition by UBA helices alpha1 and alpha3. The structure shows a larger number of intermolecular hydrogen bonds than observed in previous UBA/ubiquitin complexes. Two of these involve ordered water molecules. The functional importance of residues at the UBA/ubiquitin interface was confirmed using site-directed mutagenesis. Surface plasmon resonance (SPR) measurements show that the EDD UBA domain does not have a strong preference for polyubiquitin chains over monoubiquitin. This suggests that EDD binds to monoubiquitinated proteins, which is consistent with its involvement in DNA damage repair pathways.
