Abstract

Fission yeast cdc25+ and wee1+ interact genetically with cdc2+ in the regulation of cell division, respectively as a mitotic activator and inhibitor. cdc25+ is normally essential for mitosis, but this requirement is alleviated in a loss-of-function wee1 mutant background. A plasmid-borne sequence, other than wee1+, that causes a cdc25ts wee1- double mutant to revert to a temperature-sensitive cdc phenotype has been isolated. The gene carried by this plasmid is called bws1+ (for bypass of wee suppression). bws1+ also bypasses the ability of alleles of cdc2 that confer a wee phenotype (cdc2w) to suppress loss-of-function cdc25 mutants. The nucleotide sequence of bws1+ shows that the predicted protein shares 81% amino acid identity with the catalytic subunit of mammalian type 1 protein phosphatase. Thus a genetic screen that might have yielded a protein kinase (wee1+) uncovered a phosphatase that also appears to be involved in the pathway of mitotic control.
