RAD51-WSS1-dependent genetic pathways are essential for DNA-protein crosslink repair and pathogenesis in Candida albicans.

ABSTRACT: Genetic analyses in Saccharomyces cerevisiae suggest that nucleotide excision repair (NER), homologous recombination (HR), and protease-dependent repair pathways coordinately function to remove DNA-protein crosslinks (DPCs) from the genome. DPCs are genomic cytotoxic lesions generated because of the covalent linkage of proteins with DNA. Although NER and HR processes have been studied in pathogenic Candida albicans, their roles in DPC repair (DPCR) are yet to be explored. Proteases like Wss1 and Tdp1 (tyrosyl-DNA phosphodiesterase-1) are known to be involved in DPCR; however, Tdp1 that selectively removes topoisomerase-DNA complexes is intrinsically absent in C. albicans. Therefore, the mechanism of DPCR might have evolved differently in C. albicans. Herein, we investigated the interplay o
