Tpk1, but not other PKA components, associates with NHEJ. (A) PKA catalytic subunits, HR, NHEJ, and MRX (i.e. both NHEJ and HR) genes sharing synergistic genetic interactions (GIs; see Supplementary Table S2) with DNA damage-related genes in untreated and specific to MMS treated conditions (25,26). (B, C) Repair efficiency for plasmids (B) and HO-induced chromosomal (C; RCF, relative colony formation) DSBs on wild-type (WT) and mutant strains. Schematic (top; panel C) of the yeast JKM139 strain on chromosome III, expressing galactose-inducible HO endonuclease at MAT locus, bearing hml and hmr deletions. (D) HR efficiency of the WT and mutant strains. (E) Plasmids recovered (n ≥ 20 clones) from WT and mutant strains. Data in panels B–D are mean ± SD (n = 5 biological replicates; *P ≤ 0.05 by Student's t test).
