- Abstract
- Five new elements of the mitotic control in the fission yeast Schizosaccharomyces pombe were isolated from gene libraries as multicopy suppressors of the conditional lethal phenotype of win1-1 wee1ts cdc25ts triple mutant strains. These genes were designated wis1(+)-wis5+ for win suppressing, and do not correspond to win1+ or any of the previously characterised mitotic control genes. None of the wis genes is capable of suppressing the cdc phenotype of cdc25ts strains, suggesting that their effect is not simply to reverse the effect of loss of cdc25 function. wis1+ has been previously reported to encode a putative serine/threonine protein kinase that acts as a dosage-dependent inducer of mitosis. wis4+ appears to be a specific suppressor of the win1-1 mutation. wis2+ and wis3+ are capable of suppressing a wide range of cdc phenotypes arising from the combination of various mutations with wee1ts and cdc25ts, suggesting that the wis2+ and wis3+ products may interact with elements central to the mitotic control.
