Abstract


We used chromatin immunoprecipitation, followed by microarray hybridization, to determine the genome-wide distribution of the RNA polymerase (Pol) III transcription apparatus in the yeast Saccharomyces cerevisiae. The Pol III transcriptome includes all tRNA genes, previously identified non-tRNA Pol III genes, and SNR52, which encodes a small nucleolar RNA. Unexpectedly, we identify eight ETC loci that are occupied by TFIIIC but not by other components of the Pol III machinery. Some ETC loci contain stretches of DNA that are highly conserved among closely related yeast species, suggesting that they may encode functional RNAs. ETC6 is located upstream of the gene encoding the tau 91 subunit of TFIIIC, suggesting the possibility of Pol III-regulated expression of a critical Pol III factor. We also identify the ZOD1 locus, which is bound by all components of the Pol III machinery and yet does not appear to express an RNA conserved among closely related yeast species. The B block motifs and several flanking nucleotides of the ZOD1 and ETC loci are very similar to each other and are highly conserved across the yeast species. Furthermore, the unusual profile of Pol III factor association with ZOD1 and the ETC loci is perfectly preserved in a different Saccharomyces species, indicating that these loci represent novel functional entities.
