Towards The Identification Of The Molecular Mechanism Responsible For Rpa:Rad52 Complex Formation, Lucas Struble

Theses & Dissertations

Human cells are routinely exposed to DNA-damaging conditions, from both external sources like ionizing radiation and internal sources like normal oxidative metabolism. Damage in the form of double strand breaks (DSBs) is especially problematic. DSBs occurring outside of replication forks can be repaired through two forms of homologous recombination. The first of these is genetic conversion involving either RPA, BRCA1, PALB2, BRCA2, and RAD51, or RPA, RAD52, RAD51, and other unknown factors. The second is single strand annealing involving RPA and RAD52. Familial breast cancers, among numerous others, are characterized by homozygous pathological mutations in the BRCA2 pathway and must …
