WebAs mentioned above, DSB ends must be resected so that they can enter the HDR pathway. CtIP, a key protein in early steps of DSB resection, is essential for HDR initiation. In order to ensure the presence of functional … WebConversely, ATM is also proposed to participate in HDR (17, 18), e.g., by phosphorylating CtIP in cooperation with cyclin-dependent kinase to stimulate end resection in S/G2 phases (19–23). However, several studies have shown that ATM is not essential for HDR in some contexts, e.g., mouse embryonic stem (ES) cells ( 24 – 27 ). northone plaidWebThus, as with the resection-dependent HDR pathway, the Brca1–Ctip interaction appears to be dispensable for MMEJ repair of chromosomal DSBs. Single-strand annealing (SSA) is a mutagenic mode of DSB repair that shares some features with MMEJ (Bennardo et al., 2008; McVey and Lee, 2008). In SSA, annealing occurs between long (>30 nucleotides ... northone phone number

"WebThe decision to use NHEJ or HDR is gov-erned in part by DNA resection, a nucleolytic process in which DSB ends are converted into 3′ single-strand DNA overhangs, an essential intermediate for the downstream steps of HDR and a potent inhibitor of NHEJ.
