In fission yeast (Schizosaccharomyces pombe), progression through the cell cycle is driven by a complex that forms between two types of protein: Cdc2 (a kinase enzyme) and Cdc13 (a cyclin protein).

Interestingly, during cell division in fission yeast, microtubule shortening also occurs in the absence of kinesin-13 proteins, suggesting the involvement of other proteins.

A contractile ring of actin filaments and myosin II generates the force that constricts the cleavage furrow of animal cells, leading to cytokinesis. Studies in fission yeast have increased our ...
