Pom1

Pom1 is a polarity protein kinase in fission yeast, Schizosaccharomyces pombe (S. pombe), that localizes to cell ends and regulates cell division. As the cell lengthens, the level of Pom1 in the middle declines, which triggers mitosis. Pom1 is a relatively unique protein kinase as its closest homolog in S. pombe is only 55% identical. Homologs in other organisms include Dyrk in rats, Dyrk2 and Dyrk3 in humans, Yak1p in S. cerevisiae, and Minibrain in Drosophila and humans.
