Citation | Journal: J Biol Chem / Year: 2016 Title: RNF8 E3 Ubiquitin Ligase Stimulates Ubc13 E2 Conjugating Activity That Is Essential for DNA Double Strand Break Signaling and BRCA1 Tumor Suppressor Recruitment. Authors: Curtis D Hodge / Ismail H Ismail / Ross A Edwards / Greg L Hura / Andrew T Xiao / John A Tainer / Michael J Hendzel / J N Mark Glover / Abstract: DNA double strand break (DSB) responses depend on the sequential actions of the E3 ubiquitin ligases RNF8 and RNF168 plus E2 ubiquitin-conjugating enzyme Ubc13 to specifically generate histone Lys-63- ...DNA double strand break (DSB) responses depend on the sequential actions of the E3 ubiquitin ligases RNF8 and RNF168 plus E2 ubiquitin-conjugating enzyme Ubc13 to specifically generate histone Lys-63-linked ubiquitin chains in DSB signaling. Here, we defined the activated RNF8-Ubc13∼ubiquitin complex by x-ray crystallography and its functional solution conformations by x-ray scattering, as tested by separation-of-function mutations imaged in cells by immunofluorescence. The collective results show that the RING E3 RNF8 targets E2 Ubc13 to DSB sites and plays a critical role in damage signaling by stimulating polyubiquitination through modulating conformations of ubiquitin covalently linked to the Ubc13 active site. Structure-guided separation-of-function mutations show that the RNF8 E2 stimulating activity is essential for DSB signaling in mammalian cells and is necessary for downstream recruitment of 53BP1 and BRCA1. Chromatin-targeted RNF168 rescues 53BP1 recruitment involved in non-homologous end joining but not BRCA1 recruitment for homologous recombination. These findings suggest an allosteric approach to targeting the ubiquitin-docking cleft at the E2-E3 interface for possible interventions in cancer and chronic inflammation, and moreover, they establish an independent RNF8 role in BRCA1 recruitment. |
