Binding of inositol phosphates to arrestin [PDF]
FEBS Letters, 1991 Arrestin binds to phosphorylated rhodopsin in its light‐activated form (metarhodopsin II), blocking thereby its interaction with the G‐protein, transducin. In this study, we show that highly phosphorylated forms of inositol compete against the arrestin‐rhodopsin interaction.

Towards Improved Bioavailability of Cereal Inositol Phosphates, Myo-Inositol and Phenolic Acids [PDF]
MoleculesCereals are among the foods rich in myo-inositol hexakisphosphate (phytic acid, IP6), lower myo-inositol phosphates (IPx), a wide range of phenolic compounds, as well as vitamins, minerals, oligosaccharides, phytosterols and para-aminobenzoic acid, and ...

Inhibition of vascular calcification by inositol phosphates derivatized with ethylene glycol oligomers [PDF]
Nature Communications, 2020 Cardiovascular calcification is a serious pathology for which effective pharmacological treatments are lacking. Here the authors show that an optimized oligo(ethylene glycol) derivative of inositol phosphate interferes with calcium phosphate ...

Insights into the activation mechanism of class I HDAC complexes by inositol phosphates [PDF]
Nature Communications, 2016 Class I histone deacetylase complexes can be activated by inositol phosphates. Here, the authors investigate the stereochemical requirements for activation; use the crystal structure to understand substrate recognition, and suggest an entropically driven

Protein pyrophosphorylation by inositol phosphates: a novel post-translational modification in plants? [PDF]
Frontiers in Plant ScienceInositol pyrophosphates (PP-InsPs) are energy-rich molecules harboring one or more diphosphate moieties. PP-InsPs are found in all eukaryotes evaluated and their functional versatility is reflected in the various cellular events in which they take part ...

The intracellular inositol (pyro)phosphate receptor AtSPX1 reciprocally binds to P1BS DNA [PDF]
Nature CommunicationsThe response of plants to phosphate starvation engages PHR (CC-MYB-PHOSPHATE STARVATION RESPONSE) transcription factors that bind to P1BS (GNATATNC) promoter elements of phosphate-starvation induced (PSI) genes. The encoded proteins include single-domain

Pho84/GLUT2 are cellular myo-inositol exporters regulated by inositol pyrophosphates [PDF]
The EMBO JournalInositol is an essential nutrient for most living organisms, as combinatorial phosphorylation on this cyclic sugar generates key cellular messengers, such as lipid-bound phosphoinositides (PtdInsPs), water-soluble inositol phosphates (InsPs), and high ...

Phytase dose-dependent response of kidney inositol phosphate levels in poultry.
PLoS ONE, 2022 Phytases, enzymes that degrade phytate present in feedstuffs, are widely added to the diets of monogastric animals. Many studies have correlated phytase addition with improved animal productivity and a subset of these have sought to correlate animal ...
