Summary
Analysis of the primary structure of the gene for yeast ribosomal protein S31 revealed two unusual features. First, an intron of 312 nucleotides is located within the 5′-untranslated region. Second, the coding sequence for the known amino-terminal peptide of the protein starts 13 codons downstream of the ATG initiation codon, suggesting that S31 is synthesized as a precursor which undergoes post-translational processing to the mature protein. Primer extension analysis showed that transcription of the S31 gene starts at multiple sites. The 5′-flanking region of the gene contains several, previously described, conserved sequence elements that may play a role in the coordinate expression of yeast ribosomal protein genes.
