1JAT, 1JBB - PubMed Abstract: 
While the signaling properties of ubiquitin depend on the topology of polyubiquitin chains, little is known concerning the molecular basis of specificity in chain assembly and recognition. UEV/Ubc complexes have been implicated in the assembly of Lys63-linked polyubiquitin chains that act as a novel signal in postreplicative DNA repair and I kappa B alpha kinase activation ...
