Crystal structure and enzymology of solanum tuberosum inositol tris/tetrakisphosphate kinase 1 (StITPK1) [PDF]
Inositol phosphates and their pyrophosphorylated derivatives are responsive to the phosphate supply and are agents of phosphate homeostasis and other aspects of physiology. It seems likely that the enzymes that interconvert these signals work against the

Inositol Pyrophosphate Pyrotechnics [PDF]
Physiologic roles of highly phosphorylated inositol phosphates, including those containing pyrophosphate groups, have been the focus of much recent interest. In the April 6, 2007 issue of Science, two papers (Lee et al., 2007; Mulugu et al., 2007) demonstrate the occurrence of a novel inositol pyrophosphate molecule in yeast and elucidate its role in ...

Inositol pyrophosphates promote MYC polyubiquitination by FBW7 to regulate cell survival.
The transcription factor MYC regulates cell survival and growth, and its level is tightly controlled in normal cells. We report that serine pyrophosphorylation - a posttranslational modification triggered by inositol pyrophosphate signaling molecules ...

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.

Inositol pyrophosphates modulate cell cycle independently of alteration in telomere length [PDF]
Synthesis of inositol pyrophosphates through activation of Kcs1 plays an important role in the signalling response required for cell cycle progression after mating pheromone arrest. Overexpression of Kcs1 doubled the level of inositol pyrophosphates when

Inositol pyrophosphate 1,5-IP8 is a signaling molecule that regulates phosphate and polyphosphate homeostasis in the fission yeast Schizosaccharomyces pombe. 1,5-IP8 levels are dictated by a balance between the Asp1 kinase domain that converts 5-IP7 to 1,

Anharmonicity and structural phase transition in the Mott insulator Cu$_2$P$_2$O$_7$ [PDF]
Ab initio investigations of structural, electronic, and dynamical properties of the high-temperature $\beta$ phase of copper pyrophosphate were performed using density functional theory. The electronic band structure shows the Mott insulating state due to electron correlations in copper ions. By calculating phonon dispersion relations, the soft mode at

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
