FUNCTION: Single-stranded structure-specific DNA endonuclease involved in DNA excision repair (PubMed:8206890, PubMed:8090225, PubMed:8078765, PubMed:7651464, PubMed:32821917, PubMed:32522879). Makes the 3'incision in DNA nucleotide excision repair (NER) (PubMed:8090225, PubMed:8078765, PubMed:32821917, PubMed:32522879). Binds and bends DNA repair bubble substrate and breaks base stacking at the single-strand/double-strand DNA junction of the DNA bubble (PubMed:32522879). Plays a role in base excision repair (BER) by promoting the binding of DNA glycosylase NTHL1 to its substrate and increasing NTHL1 catalytic activity that removes oxidized pyrimidines from DNA (PubMed:9927729). Involved in transcription-coupled nucleotide excision repair (TCR) which allows RNA polymerase II-blocking lesions to be rapidly removed from the transcribed strand of active genes (PubMed:16246722). Functions during the initial step of TCR in cooperation with ERCC6/CSB to recognized stalled RNA polymerase II (PubMed:16246722). Also, stimulates ERCC6/CSB binding to the DNA repair bubble and ERCC6/CSB ATPase activity (PubMed:16246722). Required for DNA replication fork maintenance and preservation of genomic stability (PubMed:26833090, PubMed:32522879). Involved in homologous recombination repair (HRR) induced by DNA replication stress by recruiting RAD51, BRCA2, and PALB2 to the damaged DNA site (PubMed:26833090). During HRR, binds to the replication fork with high specificity and stabilizes it (PubMed:32522879). Also, acts upstream of HRR, to promote the release of BRCA1 from DNA (PubMed:26833090). {ECO:0000269|PubMed:16246722, ECO:0000269|PubMed:26833090, ECO:0000269|PubMed:32522879, ECO:0000269|PubMed:32821917, ECO:0000269|PubMed:7651464, ECO:0000269|PubMed:8078765, ECO:0000269|PubMed:8090225, ECO:0000269|PubMed:8206890, ECO:0000269|PubMed:9927729}.
