Schizosaccharomyces pombe map3+ encodes the putative M-factor receptor.

Sce3, a suppressor of the Schizosaccharomyces pombe septation mutant cdc11, encodes a putative RNA-binding protein.

In the fission yeast Schizosaccharomyces pombe, the cdc11 gene is required for the initiation of septum formation at the end of mitosis. The sce3 gene was cloned as a multi-copy suppressor of the heat-sensitive mutant cdc11-136. When over-expressed, it rescues all mutants of cdc11 and also a heat-sensitive allele of cdc14, but not the cdc14 null mutant. Deletion shows that sce3 is not essential...

The Schizosaccharomyces pombe cho1+ gene encodes a phospholipid methyltransferase.

The isolation of mutants of Schizosaccharomyces pombe defective in the synthesis of phosphatidylcholine via the methylation of phosphatidylethanolamine is reported. These mutants are choline auxotrophs and fall into two unlinked complementation groups, cho1 and cho2. We also report the analysis of the cho1+ gene, the first structural gene encoding a phospholipid biosynthetic enzyme from S. pomb...

The cdr2(+) gene encodes a regulator of G2/M progression and cytokinesis in Schizosaccharomyces pombe.

Schizosaccharomyces pombe cells respond to nutrient deprivation by altering G2/M cell size control. The G2/M transition is controlled by activation of the cyclin-dependent kinase Cdc2p. Cdc2p activation is regulated both positively and negatively. cdr2(+) was identified in a screen for regulators of mitotic control during nutrient deprivation. We have cloned cdr2(+) and have found that it encod...

M-factor, a farnesylated mating factor from the fission yeast Schizosaccharomyces pombe.

Introduction Conjugation between two haploid yeast cells is generally controlled by the reciprocal action of diffusible mating factors, cells of each mating type releasing peptide pheromones that induce mating-specific changes in cells of the opposite type. The pheromones bind to specific receptors at the surface of their target cell and binding initiates a series of intracellular events that l...
