摘要：

Ultraviolet (UV) light irradiation generates pyrimidine dimers on DNA, such as cyclobutane pyrimidine dimers (CPDs) and (6-4) photoproducts. Such dimers distort the high-order DNA structure and prevent transcription and replication. The nucleotide excision repair (NER) system contributes to resolving this type of DNA lesion. There are two pathways that recognize pyrimidine dimers. One acts on transcribed strands of DNA (transcription -coupled NER), and the other acts on the whole genome (global genome-NER; GG-NER). In the latter case, DNA damage-binding protein 2 (DDB2) senses pyrimidine dimers with several histone modification enzymes. We previously reported that histone acetyltransferase binding to ORC1 (HBO1) interacts with DDB2 and facilitates recruitment of the imitation switch chromatin remodeler at UV-irradiated sites via an unknown methyl-transferase. Here, we found that the phosphorylated histone methyltransferase mixed lineage leukemia 1 (MLL1) was maintained at UV-irradiated sites in an HBO1-dependent manner. Furthermore, MLL1 catalyzed histone H3K4 methylation and recruited the chromatin remodeler bromodomain adjacent to zinc finger domain 1A (BAZ1A)/ATP-utilizing chromatin assembly and remodeling factor 1 (ACF1). Depletion of MLL1 suppressed BAZ1A accumulation at UV-irradiated sites and inhibited the removal of CPDs. These data indicate that the DDB2-HBO1-MLL1 axis is essential for the recruitment of BAZ1A to facilitate GG-NER.
