Double-stranded RNA (dsRNA) triggers RNA interference (RNAi) to silence genes of matching sequence. In some animals this experimentally induced silencing is transported between cells, and studies in the nematode Caenorhabditis elegans have shown that the dsRNA channel SID-1 is required for the import of such transported silencing signals. Gene silencing can also be triggered by endogenously exp...
Transcriptional silencing in Saccharomyces cerevisiae occurs at the silent mating-type loci HML and HMR, at telomeres, and at the ribosomal DNA (rDNA) locus RDN1. Silencing in the rDNA occurs by a novel mechanism that depends on a single Silent Information Regulator (SIR) gene, SIR2. SIR4, essential for other silenced loci, paradoxically inhibits rDNA silencing. In this study, we elucidate a re...
