Protein

WD repeat-containing protein pop1

Gene

pop1

Organism
Schizosaccharomyces pombe (strain 972 / ATCC 24843) (Fission yeast)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Involved in maintenance of ploidy through proteasome dependent degradation of CDK inhibitor rum1 and S-phase initiator cdc18. Functions as a recognition factor for rum1 and cdc18, which are subsequently ubiquitinated and targeted to the 26S proteasome for degradation. Together with pop2, required for cig2 instability during G2 and M phase and cig2 degradation in exponentially growing cells. Regulates cell-cycle progression under starvation through the rum1 protein.4 Publications
