Skp1 and the F-box protein Pof6 are essential for cell separation in fission yeast.

Abstract excerpt

Here we report functional characterization of the essential fission yeast Skp1 homologue. We have created a conditional allele of skp1 (skp1-3f) mimicking the mutation in the budding yeast skp1-3 allele. Although budding yeast skp1-3 arrests at the G(1)/S transition, skp1-3f cells progress through S phase and instead display two distinct phenotypes. A fraction of the skp1-3f cells arrest in mitosis with high Cdc2...
