WebDuring HR, CtIP (CtBP-interacting protein) binds NBS1 in the MRN complex [134], changing the organization of the three proteins in the complex. The MRN complex moves inwards along the double-stranded DNA and the Mre11 protein, representing the “M” in the MRN complex, cleaves one of the strands (the one which has a 5′ end at the point of ... WebApr 2, 2024 · The domain of CtIP required to promote DNA2 is located in the central region lacking in lower eukaryotes and is fully separable from domains involved in the stimulation of MRN. These results establish how CtIP couples both MRE11-dependent short-range and DNA2-dependent long-range resection and define the involvement of the motor activity of ...

Here, we show that human cells arrested in G0/G1 repair etoposide-induced DSBs by NHEJ and, surprisingly, require the MRN complex (the ortholog of MRX) and CtIP.
WebSep 27, 2024 · The HR pathway begins with nucleolytic resection of DNA ends, which is mediated by Mre11-Rad50-Nbs1 (MRN)complex, breast cancer susceptibility (BRCA1) and CtIP. The key-players of HR mechanism yield 3′ single-stranded DNA tails that are stabilized by replication protein A (RPA), while CtIP promotes HR by initiating DSB end resection … WebCtIP (CtBP-interacting protein) associates with BRCA1 and the Mre11-Rad50-Nbs1 (MRN) complex and plays an essential role in homologous recombination (HR)-mediated DNA double-stranded break (DSB) repair. It has been described that CtIP forms dimers in mammalian cells, but the biological significance is not clear.
WebThe MMEJ pathway inhibitor can be a CtIP or MRN inhibitor. The CtIP inhibitor can be selected from KLHL15 and PIN1. The MRN inhibitor can be selected from E1b55K and E40rf6. [0021] In some embodiments, a first nucleic acid …
