... [1,2]. In the nucleus of eukaryotic cells, the DNA is packaged into chromatin, and repair of DNA lesions therefore occurs within the context of chromatin. The DNA repair rate in chromatin is slower ... was found to be involved in the TCR subpathway [14]. The HMGN1-mediated enhancement of DNA repair in chromatin was linked to the ability of HMGN1 to bind to...
