Promoter architecture and transcriptional regulation of Abf1-dependent ribosomal protein genes in Saccharomyces cerevisiae
In Saccharomyces cerevisiae, ribosomal protein gene (RPG) promoters display binding sites for either Rap1 or Abf1 transcription factors. Unlike Rap1-associated promoters, the small cohort of Abf1-dependent RPGs (Abf1-RPGs) has not been extensively investigated. We show that RPL3, RPL4B, RPP1A, RPS22B and RPS28A/B share a common promoter architecture, with an Abf1 site upstream of a conserved el...
متن کاملUpstream activation of ribosomal RNA biosynthesis in Saccharomyces cerevisiae.
Yeast was transformed with eight recombinants that contained an rRNA minigene and upstream elements of rDNA in different orientations in the multi-copy yeast-Escherichia coli shuttle vector, pJDB207. The effect of these elements of upstream rDNA on the initiation of transcription of the minigene at the site for rRNA biosynthesis was determined by using an S1 nuclease mapping procedure to measur...
متن کاملSuppressors of Saccharomyces cerevisiae his3 promoter mutations lacking the upstream element.
Transcription of the Saccharomyces cerevisiae his3 gene requires an upstream promoter element and a TATA element. A strain containing his3-delta 13, an allele which deletes the upstream promoter element but contains the TATA box and intact structural gene, fails to express the gene and consequently is unable to grow in medium lacking histidine. In this paper we characterize His+ revertants of h...
متن کاملMagnification of genes coding for ribosomal RNA in Saccharomyces cerevisiae.
When a strain of Saccharomyces cerevisiae monosomic for chromosome I and initially deficient for 25% of the genes coding for ribosomal RNA is repeatedly subcultured, the number of these genes increases to and remains stable at the number in the wild type. This strain shows 2:2; viable: inviable first division segregation and hemizygosity for the ade1 gene (a chromosome I marker), evidence that ...
متن کاملSaccharomyces cerevisiae ribosomal protein L26 is not essential for ribosome assembly and function.
Ribosomal proteins play important roles in ribosome biogenesis and function. Here, we study the evolutionarily conserved L26 in Saccharomyces cerevisiae, which assembles into pre-60S ribosomal particles in the nucle(ol)us. Yeast L26 is one of the many ribosomal proteins encoded by two functional genes. We have disrupted both genes; surprisingly, the growth of the resulting rpl26 null mutant is ...
