Figure 1. γH2A forms in the mating-type locus during DNA replication.

Figure 1

(A) Diagram of a typical S. pombe mating-type (MT) locus (not to scale). Symbols: cen2 –centromere2, RTS1-polar replication fork barrier, DSB- imprinting site where DSB forms during replication; purple arrows - inverted repeats. Primer names correspond to distance in kilobases from the DSB. (B) ChIP-qPCR analysis of γH2A distribution at the MT locus in G2 and S phase. Cells were synchronized in G2 phase using the cdc25-22 allele and S-phase progression was monitored using septation index. ChIP enrichment at the indicated sites was quantitated %IP.
