Insights into Spt6: a histone chaperone that functions in transcription, DNA replication, and genome stability

Trends Genet. 2023 Jul 20:S0168-9525(23)00152-X. doi: 10.1016/j.tig.2023.06.008. Online ahead of print.ABSTRACTTranscription elongation requires elaborate coordination between the transcriptional machinery and chromatin regulatory factors to successfully produce RNA while preserving the epigenetic landscape. Recent structural and genomic studies have highlighted that suppressor of Ty 6 (Spt6), a conserved histone chaperone and transcription elongation factor, sits at the crux of the transcription elongation process. Other recent studies have revealed that Spt6 also promotes DNA replication and genome integrity. Here, we review recent studies of Spt6 that have provided new insights into the mechanisms by which Spt6 controls transcription and have revealed the breadth of Spt6 functions in eukaryotic cells.PMID:37481442 | DOI:10.1016/j.tig.2023.06.008
