About this page: This table was intended to provide a quick translation from S. pombe to S. cerevisiae homologues prior to the genome publication and curation. It is no longer maintained but is left here because it may be helpful in some circumstances. For details and most up to date information, we suggest you go to genedb. There is also a group particularly interested in orthologues to which you can subscribe here: http://publists.sanger.ac.uk/mailman/listinfo/yeast_orthologous_group

Fission yeast genes are listed alphabetically under just one name, but their aliases are listed alongside. If you can’t find the gene you want in its alphabetical position, use the search feature of your browser to see if it is listed under a synonym. One yeast may have a pair of genes where the other has just one. These cases are indicated by the word “and”; otherwise multiple gene names are aliases. In a few cases, the same gene designation may have been used for different genes which we have noted.

Recall that just because there is a cerevisiae homologue of a pombe gene doesn’t mean they work the same way, and that genes without primary sequence homology can be functional homologues.
