Phosphorylation process in dna replication
WebSep 9, 2024 · Upon DSBs, phosphorylation of H2AX (γ-H2AX) initiates recruitment of MDC1, RNF8, and RNF168 in a hierarchal manner. In G1, accumulation of 53BP1 and RIF1 at the break promotes repair by nonhomologous end joining (NHEJ). In S-G2, homologous recombination repair (HRR) is promoted by the complex BRCA1-CtIP.
