title: A position effect on the expression of a tRNA gene mediated by the SIR genes in Saccharomyces cerevisiae.
abstract: The SIR genes of Saccharomyces cerevisiae are responsible for the position-dependent regulation of the a and alpha mating-type genes. Previous work by others has shown that the products of the SIR genes prevent the accumulation of stable transcripts of the a and alpha genes at HML and HMR. Results of this study establish that this regulation is a region-specific effect rather than a gene-specific effect since expression of a tRNA gene placed at HMR is repressed by the products of the SIR genes.
