- Abstract
Abstract: The histone chaperones play an important role in chromatin assembly and disassembly during replication and transcription. We have assessed the global roles of histone chaperones in Saccharomyces cerevisiae. Microarray transcriptional analyzes indicate that histone chaperones have their own specific target genes, and various histone chaperones have partially overlapping functions during transcriptional regulation. The histone deacetylase inhibitor TSA and histone chaperones Asf1, Vps75 and Rtt106 can function in parallel pathways to regulate transcription. Moreover, TSA can specifically antagonize histone chaperone Chz1-mediated telomere anti-silencing. This study demonstrates that a mutual cross-talk mechanism exists between histone chaperones and histone deacetylation in transcriptional regulation.
