Brca1 repair pathway

WebMar 22, 2024 · Collectively, strong evidence indicates that BRCA1, BRCA2, and PARP1 are all implicated in preventing replication stress and facilitating the repair/re-start of stalled replication forks at the CFSs. PARP1 likely functions in a parallel pathway of BRCA1 and BRCA2 in these molecular processes. WebBRCA1 is part of a complex that repairs double-strand breaks in DNA. The strands of the DNA double helix are continuously breaking as they become damaged. Sometimes only one strand is broken, sometimes both …
