The artificial inhibition of expression of genes in Saccharomyces cerevisiae is not a widespread, useful phenomenon. The external guide sequence (EGS) technology, which is well-proven in bacteria and mammalian cells in tissue culture and in mice, can also be utilized in yeast. The TOP2 and SRG1 genes can be inhibited by approximately 30% with EGSs in vivo. Results in vitro also show convenient cleavage of the relevant transcripts by RNase P and appropriate EGSs. The feasible constructs shown to date have an EGS covalently linked to M1 RNA, the RNA subunit of RNase P from Escherichia coli. Greater efficiency in cleavage of transcripts can be fashioned using more than one EGS targeted to different sites in a transcript and stronger promoters controlling the EGS constructs.
