To gain a better understanding of this important control mechanism, we examined the DNA replication and transcription using the Dbf4 origin-promoter and Dbf4 pseudogene models. We found that origin firing and Dbf4 transcription activity were inversely regulated in a cell cycle-dependent manner. We also found that proteins critical for the regulation of replication (ORC, MCM), transcription (SP1, TFIIB), and cohesin (Smc1, Smc3) and Mediator functions (Med1, Med12) interact with specific sites within and the surrounding regions of the Dbf4 locus in a cell cycle-dependent manner. As expected, replication initiation occurred within a nucleosome-depleted region, and nucleosomes flanked the 2 replication initiation zones. Further, the histone H3 in this region was distinctly acetylated or trimethylated on lysine 9 in a cell cycle-dependent fluctuation pattern: H3K9ac was most prevalent when the Dbf4 transcription level was highest whereas the H3K9me3 level was greatest during and just after replication. The KDM4A histone demethylase, which is responsible for the H3K9me3 modification, was enriched at the Dbf4 origin in a manner coinciding with H3K9me3. Finally, HP1γ, a protein known to interact with H3K9me3 in the heterochromatin was also found enriched at the origin during DNA replication, indicating that H3K9me3 may be required for the regulation of replication at both heterochromatin and euchromatin regions. Taken together, our data show that mammalian cells employ an extremely sophisticated and multilayered co-regulation mechanism for replication and transcription in a highly coordinated manner."xsd:string |
