Cdk1 targets Srs2 to complete synthesis-dependent strand annealing and to promote
Original language description
Cdk1 kinase phosphorylates budding yeast Srs2, a member of UvrD protein family that displays both DNA translocation and DNA unwinding activities in vitro. Srs2 prevents homologous recombination by dismantling Rad51 filaments and it is also required for double strand break repair. Here we examine the biological significance of Cdk1-dependent phosphorylation of Srs2 using mutants that constitutively express the phosphorylated or unphosphorylated isoforms. We found that Cdk1 targets Srs2 to repair double strand break (DSB) after strand invasion. Srs2 phosphorylation is required to complete synthesis-dependent strand annealing pathway, likely controlling the disassembly of the D-loop intermediate. Cdk1 phosphorylation, indeed, controls the turnover of Srs2protein at the invading strand, while it is not required for that of Rad51.
