Identification of open reading frames in Schizosaccharomyces pombe cDNAs

Abstract

A total of 214 non-overlapping cDNA clones from Schizosaccharomyces pombe were selected and completely sequenced. The clones not previously reported were divided into the following three groups: 1) homologous to Saccharomyces cerevisiae genes (139 clones); 2) homologous to genes from other organisms but not to those from Sac. cerevisiae (4 clones); and 3) no similar sequences (40 clones). Among the 31 sequences identical to those in the public databases, 4 genes have regions corresponding to introns. Protein sequences which had homologs both in budding yeast and mammals were compared with those from Sac. cerevisiae and mammals. The search revealed that the evolutionary distances among these species are similar at least with genes of this category.
