Fig. 5. Rad52-ChIPseq preserves strand-specific Rad52 signal from an irreparable DSB.
(A) In the DBS model system strain (Fig. 3B) induction of HO nuclease makes an irreparable DSB at the MAT locus, both ends are then resected 5′-3′ leaving the ssDNA Watson (W) strand on one side and the Crick (C) on the other side to be coated by Rad52. (B) Rad52-ChIPseq signal from the MAT locus after HO induction. Signal coming from the W strand is shown in red while C strand signal is in blue. Rad52-ChIPseq correctly preserve the strand-specific information on Rad52 binding around a DSB.
