Of the approximately 1000 Hmt1-binding sites found, the majority fall within or proximal to an ORF. However, Hmt1 occupancy is found at a number of other genomic features such as tRNA and snoRNA genes, thereby implicating a regulatory role in the biogenesis of these non-coding RNAs. RNA hybridization analysis shows that Hmt1 loss-of-function mutants display higher steady-state tRNA abundance relative to the wild-type. Co-immunoprecipitation studies show that Hmt1 interacts with the TFIIIB component Bdp1, suggesting a role for Hmt1 in modulating RNA pol III transcription to regulate tRNA production.2012/12/25GSE40505GSM995381GSM995380GSM9953791546940505Saccharomyces cerevisiae[23268696]
