In all eukaryotes, entry into mitosis from G2 phase is initiated by a complex of the cdc2 kinase and a B-type cyclin. It has now been shown that, in fission yeast, B-type cyclins also activate cdc2 in G1, thus governing cell-cycle commitment, as well as the onset of S phase. In this article, Karim Labib and Sergio Moreno review the evidence that rum1 inhibits the kinase activity of cdc2 associated with B-type cyclins and is an important regulator of G1 progression in fission yeast.
