Two RING finger proteins mediate cooperation between ubiquitin-conjugating enzymes in DNA repair.

Abstract

Two ubiquitin-conjugating enzymes, RAD6 and the heteromeric UBC13-MMS2 complex, have been implicated in post-replicative DNA damage repair in yeast. Here we provide a mechanistic basis for cooperation between the two enzymes. We show that two chromatin-associated RING finger proteins, RAD18 and RAD5, play a central role in mediating physical contacts… (More)
