Interstrand crosslink icl repair
WebJan 3, 2024 · TRAIP is a key factor involved in the DNA damage response (DDR), homologous recombination (HR) and DNA interstrand crosslink (ICL) repair. However, the exact functions of TRAIP in these processes in mammalian cells are not fully understood. ... Replication fork reversal during DNA interstrand crosslink repair requires CMG … WebHere we examined the ability of the glycosylase domain of murine NEIL3 (MmuNEIL3-GD) to unhook dA-AP ICLs. The enzyme selectively unhooks the dA-AP ICL located at the duplex/single-strand junction of splayed duplexes that model the strand-separated DNA at the leading edge of a replication fork. We show that the ability to unhook the dA-AP ICL ...

We show that AMX-1 mainly localizes to embryonic, the mitotic gut and sheath cells, suggesting a role in mitotic nuclei.
WebDrugs that produce DNA interstrand crosslinks (ICLs), between the two complementary strands of the double helix, have an important role in chemotherapy regimens for cancer. … WebJun 12, 2024 · During replication-coupled DNA interstrand crosslink (ICL) repair, the XPF-ERCC1 endonuclease is required for the incisions that release, or “unhook”, ICLs, but the mechanism of ICL unhooking remains largely unknown. Incisions are triggered when the nascent leading strand of a replication fork strikes the ICL.
