1MBY - PubMed Abstract: 
The small family of polo-like kinases (Plks) includes Cdc5 from Saccharomyces cerevisiae, Plo1 from Schizosaccharomyces pombe, Polo from Drosophila melanogaster and the four mammalian genes Plk1, Prk/Fnk, Snk and Sak. These kinases control cell cycle progression through the regulation of centrosome maturation and separation, mitotic entry, metaphase to anaphase transition, mitotic exit and cytokinesis ...
