REV1 and DNA polymerase zeta in DNA interstrand crosslink repair

WebDNA interstrand cross-links are complex lesions, highly toxic to cells, and difficult to repair because of the involvement of both strands of the DNA duplex. A single unrepaired inter-strand cross-link is sufficient to kill a cell, and multiple DNA repair pathways may be required to complete cross-link re-moval (1–7). WebLoss of C17orf53 slowed down DNA replication and led to pronounced interstrand crosslink (ICL) repair defect. We showed that C17orf53 is a ssDNA- and RPA-binding protein and both characteristics are important for its functions in the cell. blackstone alternative solutions 2016 trust https://0800solarpower.com
