Primary structure of the ribosomal protein gene S6 from Schizosaccharomyces pombe.

We have determined the nucleotide sequence of a ribosomal protein gene which codes for the ribosomal protein S6 (rps6). The sequence analysis revealed that the gene comprises 239 amino acids, giving rise to a basic protein with a molecular weight of 27,502 Da. The product of this gene is the equivalent of the ribosomal protein S10 from Saccharomyces cerevisiae. Northern analyses and S1 mapping of both the 5' and the 3' end of the transcripts of this gene show that it is transcribed into three distinct transcripts with different sizes and heterogeneous termini. In the DNA region flanking the coding sequence, several conserved elements are present that may be involved in the transcription initiation and termination.
