Translocation of XRCC1 and DNA ligase III from centrosomes to chromosomes in response to DNA damage in mitotic human cells
7 Jan 2005
Abstract excerpt
DNA single-strand breaks (SSBs) are the most frequent lesions caused by oxidative DNA damage. They disrupt DNA replication, give rise to double-strand breaks and lead to cell death and genomic instability. It has been shown that the XRCC1 protein plays a key role in SSBs repair. We have recently shown in living human cells that XRCC1 accumulates at SSBs in a fully poly(ADP-ribose) (PAR) synthesis-dependent manner...
