The Schizosaccharomyces pombe septation initiation network (SIN) is required for spore formation in meiosis.
When nutrients are abundant, S. pombe cells grow as rods, dividing by fission after formation of a medially placed cell wall or division septum. Septum formation is triggered by a group of proteins, called the septation initiation network or SIN, that trigger contraction of the acto-myosin contractile ring at the end of mitosis. Ectopic activation of the SIN can uncouple septum formation from o...
متن کاملA control acting over the initiation of DNA replication in the yeast Schizosaccharomyces pombe.
The control of cell division in the yeast Schizosaccharomyces pombe appears to be quite different to that of any other eukaryotic organisms for it is usually exerted not at the initiation of S-phase but at that of mitosis. However, it has been suggested that a control over the initiation of S-phase does also exist but that its action is redundant whilst the mitotic control is operating. This st...

Genetic interactions in the control of septation in Schizosaccharomyces pombe.
We have used genetic and molecular techniques to investigate the interactions among genes required for the initiation and regulation of septum formation in Schizosaccharomyces pombe. Our data suggest that the products of the cdc7, cdc11, cdc14 and cdc16 genes interact. These activities may regulate the function of the cdc15 gene product. A model for the control of septation in fission yeast is ...
متن کاملSchizosaccharomyces pombe Ste7p is required for both promotion and withholding of the entry to meiosis.
The fission yeast ste7 mutant cannot mate and undergo meiosis, but shows no defect in vegetative growth. We cloned and characterized the ste7 gene. The deduced ste7 gene product (Ste7p) was a protein of 569 amino acids with no significant similarity to other proteins. Transcription of ste7 was induced by nutrient starvation via the function of the transcription factor Ste11p. Disruption of the ...
