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 ). WebJun 17, 2016 · Together, our biochemical analyses explain the specific hypersensitivity of cells deficient in MRN, CtIP, or BRCA1 to etoposide poisons. Our work supports a role for the MRN-CtIP-BRCA1 pathway as a cell cycle-regulated nuclease activity that releases blocks on the DNA during replication and favors HDR (see Fig. 1). We speculate that …

WebFeb 21, 2013 · How resection and HDR are activated during DDR is not known, nor are the roles of ATM and ATR in HDR. Here, we show that CtIP undergoes ATR-dependent hyperphosphorylation in response to DSBs. ATR phosphorylates an invariant threonine, T818 of Xenopus CtIP (T859 in human).

MMEJ is initiated by a limited resection of DNA DSB ends by the MRN complex (MRE11A:RAD50:NBN) and RBBP8 (CtIP), in the absence of CDK2-mediated RBBP8 phosphorylation and related BRCA1:BARD1 recruitment (Yun and Hiom 2009).

(A) Cas9 induced double-strand breaks are either repaired by HDR or the prevailing NHEJ pathway. DSB repair pathway choice is largely …
WebAdditionally, Cas9-CtIP, a fusion of Cas9 and CtIP, a protein involved in double-stranded break resection, can contribute to increased HDR efficiency. Since the efficiency of Cas9 cleavage is relatively high and the efficiency of HDR is relatively low, a large portion of the Cas9-induced DSBs will be repaired via NHEJ. WebJun 28, 2024 · CRISPR-mediated genome editing has become a powerful tool for genetic modification of biological traits. However, developing an efficient, site-specific, gene knock-in system based on homology-directed DNA repair (HDR) remains a significant challenge in plants, especially in woody species like poplar. Here, we show that simultaneous …
