Structural insight into inositol pyrophosphate turnover [PDF]
The diphosphoinositol polyphosphates ("inositol pyrophosphates"; PP-InsPs) regulate many cellular processes in eukaryotes, including stress responses, apoptosis, vesicle trafficking, cytoskeletal dynamics, exocytosis, telomere maintenance, insulin signaling and neutrophil activation.

Development of a homogenous high-throughput assay for inositol hexakisphosphate kinase 1 activity. [PDF]
Inositol pyrophosphates have been implicated in a wide range of cellular processes. Inositol hexakisphosphate kinase 1 catalyzes the pyrophosphorylation of inositol hexakisphosphate into inositol 5-diphospho-1,2,3,4,6-pentakisphosphate which is important

Inositol pyrophosphates regulate endocytic trafficking [PDF]
The high energy potential and rapid turnover of the recently discovered inositol pyrophosphates, such as diphosphoinositol-pentakisphosphate and bis-diphosphoinositol-tetrakisphosphate, suggest a dynamic cellular role, but no specific functions have yet been established.

The Role of Inositol Hexakisphosphate Kinase in the Central Nervous System
Inositol is a unique biological small molecule that can be phosphorylated or even further pyrophosphorylated on each of its six hydroxyl groups. These numerous phosphorylation states of inositol along with the kinases and phosphatases that interconvert ...

Versatile signaling mechanisms of inositol pyrophosphates
Inositol pyrophosphates (PP-InsPs) constitute a group of highly charged messengers, which regulate central biological processes in health and disease, such as cellular phosphate and general energy homeostasis. Deciphering the molecular mechanisms underlying PP-InsP-mediated signaling remains a challenge due to the unique properties of these molecules ...

Inositol Pyrophosphates Get the Vip1 Treatment [PDF]
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 ...
