Synthesis pass · prose summary of the discoveries below

RNF168 is a RING-type E3 ubiquitin ligase that functions as a central amplifier of chromatin ubiquitin signals at DNA double-strand breaks, coordinating the recruitment of repair factors to dictate DSB repair pathway choice. Recruited downstream of RNF8 via ubiquitylated L3MBTL2 and K63-polyubiquitylated linker histone H1, RNF168 engages the nucleosome acidic patch through its RING domain and catalyzes site-specific monoubiquitination of H2A/H2AX at K13/K15 — marks read by 53BP1 and BARD1-BRCA1 to promote NHEJ and homologous recombination, respectively (PMID:22980979, PMID:30704900, PMID:39394267). Beyond histones, RNF168 ubiquitinates JMJD2A (freeing H4K20me2 for 53BP1 binding), 53BP1 itself (enabling its initial DSB recruitment), DHX9 (facilitating R-loop resolution), TOP2α, PARP1, and HDAC6, thereby integrating chromatin remodeling with DNA repair (PMID:22373579, PMID:24324146, PMID:33529165, PMID:27558965, PMID:37503842). RNF168 activity is tuned by a multi-layered regulatory code: K63-polyubiquitin-triggered liquid–liquid phase separation amplifies its catalytic output, while mTOR-S6K phosphorylation at S60 inhibits it, CDK1/2-PIN1-mediated SUMOylation at T208/K210 promotes p97-dependent removal from chromatin, SENP1 deSUMOylation prevents inhibitory LLPS, and USP7 stabilizes the protein by counteracting its own ubiquitin-dependent turnover (PMID:38968116, PMID:29403037, PMID:40229270, PMID:37350666, PMID:25894431).
