Functional substitution of mouse ribosomal protein L27' for yeast ribosomal protein L29 in yeast ribosomes.
A cDNA clone of mouse ribosomal protein L27' was shown previously to be 62% identical in amino acid residues to yeast ribosomal protein L29. The L27' cDNA was expressed in yeast to determine the ability of the mouse protein to substitute for yeast L29 in assembling a functional ribosome. In a yeast strain resistant to cycloheximide by virtue of a recessive mutation in the L29 protein, the murin...
متن کاملIntrons within Ribosomal Protein Genes Regulate the Production and Function of Yeast Ribosomes
In budding yeast, the most abundantly spliced pre-mRNAs encode ribosomal proteins (RPs). To investigate the contribution of splicing to ribosome production and function, we systematically eliminated introns from all RP genes to evaluate their impact on RNA expression, pre-rRNA processing, cell growth, and response to stress. The majority of introns were required for optimal cell fitness or grow...
متن کاملStepwise Splitting of Ribosomal Proteins from Yeast Ribosomes by LiCl
Structural studies have revealed that the core of the ribosome structure is conserved among ribosomes of all kingdoms. Kingdom-specific ribosomal proteins (r-proteins) are located in peripheral parts of the ribosome. In this work, the interactions between rRNA and r-proteins of eukaryote Saccharomyces cerevisiae ribosome were investigated applying LiCl induced splitting and quantitative mass sp...
متن کاملA comparison of yeast ribosomal protein gene DNA sequences.
The DNA sequences of eight yeast ribosomal protein genes have been compared for the purpose of identifying homologous regions which may be involved in the coordinate regulation of ribosomal protein synthesis. A 12 bp homology was identified in the 5' DNA sequence preceding the structural gene for 6 out of 8 yeast ribosomal protein genes. In each case the homologous sequence was found at a posit...
متن کاملDiscoordinate expression of the yeast mitochondrial ribosomal protein MRP1.
We have examined expression of the protein coded within the MRP 1 locus of Saccharomyces cerevisiae. Direct evidence is provided for the assignment of the MRP1 gene product as a protein component of the small subunit of mitochondrial ribosomes. Further studies examined the extent to which the expression of the MRP1 protein is coordinated with the expression of other mitochondrial ribosomal comp...
