Isr1 is a negative regulator of the hexosamine biosynthesis pathway (HBP), which produces UDP-GlcNAc, an essential carbohydrate that is the building block of N-glycosylation, GPI anchors and chitin. Isr1 was recently shown to be regulated by phosphorylation by the nutrient-responsive CDK kinase Pho85, allowing it to be targeted for degradation by the SCFCDC4. Here, we show that while deletion of PHO85 stabilizes Isr1 in asynchronous cells, Isr1 is still unstable in mitotically arrested cells in a pho85∆ strain. We provide evidence to suggest that this is through phosphorylation by CDK1. Redundant targeting of Isr1 by two distinct kinases may allow for tight regulation of the HBP in response to different cellular signals."xsd:string |
