WebAug 25, 2024 · USP4 interacts with CtIP and MRN and promotes CtIP recruitment and DNA repair. As such, ubiquitination and deubiquitination can affect the DNA end resection function of CtIP. In a recent report, USP52 was revealed to interact with CtIP and deubiquitinate it, thereby promoting DNA end resection and HR (Gao et al., 2024). Over … WebIsobe et al. show that PP1 acts as a RIF1 effector distinct from shieldin in DNA damage repair. RIF1-PP1 inhibits the initiation of resection by CtIP-MRN prior to shieldin action. PP1 and shieldin, as RIF1 effectors, cooperate to suppress premature homologous recombination in the early stage of the damage response.
