Abstract
Inositol pyrophosphates are unique signaling molecules implicated in the regulation of diverse cellular processes. Two new studies by Mulugu et al. (2007) and Lee et al. (2007) extend the biological and metabolic diversity of this class of molecules. They identify yeast Vip1 as a new inositol pyrophosphate synthase and show that the products of Vip1 activity regulate a cyclin/cyclin-dependent kinase complex.
