Abstract


Based on genetic and bioinformatic analysis, 80 proteins from the newly sequenced Schizosaccharomyces pombe genome appear to be splicing factors. The fission yeast splicing factors were compared to those of Homo sapiens and Saccharomyces cerevisiae in order to determine the extent of conservation or divergence that has occurred over the billion years of evolution that separate these organisms. Our results indicate that many of the factors present in all three organisms have been well conserved throughout evolution. It is calculated that 38% of the fission yeast splicing factors are more similar to the human proteins than to the budding yeast proteins (>10% more similar or similar over a greater region). Many of the factors in this category are required for recognition of the 3' splice site. Ten fission yeast splicing factors, including putative regulatory factors, have human homologs, but no apparent budding yeast homologs based on sequence data alone. Many of the budding yeast factors that are absent in fission yeast are associated with the U1 and U4/U6.U5 snRNP. Collectively the data presented in this survey indicate that of the two yeasts, S.POMBE: contains a splicing machinery more closely reflecting the archetype of a spliceosome.
