MBF (or DSC1) is known to regulate transcription of a set of G(1)/S-phase genes encoding proteins involved in regulation of DNA replication. Previous studies have shown that MBF binds not only the promoter of G(1)/S-phase genes, but also the constitutive genes; however, it was unclear if the MBF bindings at the G(1)/S-phase and constitutive genes were mechanistically distinguishable. Here, we report a chromatin immunoprecipitation-microarray (ChIP-chip) analysis of MBF binding in the Schizosaccharomyces pombe genome using high-resolution genome tiling microarrays. ChIP-chip analysis indicates that the majority of the MBF occupancies are located at the intragenic regions. Deconvolution analysis using Rpb1 ChIP-chip results distinguishes the Cdc10 bindings at the Rpb1-poor loci (promoters) from those at the Rpb1-rich loci (intragenic sequences). Importantly, Res1 binding at the Rpb1-poor loci, but not at the Rpb1-rich loci, is dependent on the Cdc10 function, suggesting a distinct binding mechanism. Most Cdc10 promoter bindings at the Rpb1-poor loci are associated with the G(1)/S-phase genes. While Res1 or Res2 is found at both the Cdc10 promoter and intragenic binding sites, Rep2 appears to be absent at the Cdc10 promoter binding sites but present at the intragenic sites. Time course ChIP-chip analysis demonstrates that Rep2 is temporally accumulated at the coding region of the MBF target genes, resembling the RNAP-II occupancies. Taken together, our results show that deconvolution analysis of Cdc10 occupancies refines the functional subset of genomic binding sites. We propose that the MBF activator Rep2 plays a role in mediating the cell cycle-specific transcription through the recruitment of RNAP-II to the MBF-bound G(1)/S-phase genes.
