All these studies indicate the possibility that disruption of nucleosomes can take place independently of replication and can be coupled with transcription.The exchange of core histones on mitotic chromatin at anaphase and telophase observed by FRAP may reflect the replacement of a subset of nucleosomes in genome regions that are transcriptionally reactivated in the earliest parts of the new cell cycle. This interpretation is consistent with evidence of chromatin remodeling and chromatin association with RNA pol II at the anaphase–telophase transition (Fig. 9; Prasanth et al., 2003). In situ incorporation of Br-U for 5 min at the same stage showed little labeling outside of NORs (Fig. 9), suggesting that the majority of transcription is yet to commence at this point. The replacement of core histones conceivably precedes transcription to allow the clearance of promoter regions for factors to engage. |

Transcription initiation is a major regulatory step in eukaryotic gene expression. Co-activators establish transcriptionally competent promoter architectures and chromatin signatures to allow the formation of the pre-initiation complex (PIC), comprising RNA polymerase II (Pol II) and general transcription factors (GTFs).|this observation appears remarkably prevalent for chromatin-modifying and remodeling complexes. Here, we use the modular organization of the evolutionary conserved Spt-Ada-Gcn5 acetyltransferase (SAGA) complex as a paradigm to illustrate how co-activators share and combine a relatively limited set of functional tools. |
