Bre1/RNF20 promotes Rad51-mediated strand exchange and antagonizes the Srs2/FBH1 helicases
Abstract Central to homologous recombination (HR) is the assembly of Rad51 recombinase on single-strand DNA (ssDNA), Soft Toy forming the Rad51-ssDNA filament.How the Rad51 filament is efficiently established and sustained remains partially understood.Here, we find that the yeast ubiquitin ligase Bre1 and its human homolog RNF20, a tumor suppressor
