A linear pathway for inositol pyrophosphate metabolism revealed by 18O labeling and model reduction.
The homeostasis of intracellular inorganic phosphate is essential for eukaryotic metabolism and is regulated by the INPHORS signalling pathway, which employs inositol pyrophosphates (IPPs) as key intermediary messengers.

VIH2 Regulates the Synthesis of Inositol Pyrophosphate InsP₈ and Jasmonate-Dependent Defenses in Arabidopsis [PDF]
Diphosphorylated inositol polyphosphates, also referred to as inositol pyrophosphates, are important signaling molecules that regulate critical cellular activities in many eukaryotic organisms, such as membrane trafficking, telomere maintenance, ribosome

Science: Pathogenic fungi exploit plant phosphate sensing via Nudix hydrolase effectors
Inorganic phosphate (Pi) homeostasis in plants is regulated by inositol pyrophosphates (PP-InsPs), which mediate phosphate starvation responses. While beneficial microorganisms, such as arbuscular mycorrhizal fungi, contribute to phosphate uptake ...

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

A small signaling domain controls PPIP5K phosphatase activity in phosphate homeostasis
Inositol pyrophosphates (PP-InsPs) are eukaryotic nutrient messengers. The N-terminal kinase domain of diphosphoinositol pentakisphosphate kinase (PPIP5K) generates the messenger 1,5-InsP8, the C-terminal phosphatase domain catalyzes PP-InsP breakdown ...
