A Solanum tuberosum inositol phosphate kinase (StITPK1) displaying inositol phosphate–inositol phosphate and inositol phosphate–ADP phosphotransferase activities [PDF]
FEBS Letters, 2008 We describe a multifunctional inositol polyphosphate kinase/phosphotransferase from Solanum tuberosum, StITPKα (GenBank accession number: EF362784), hereafter called StITPK1. StITPK1 displays inositol 3,4,5,6‐tetrakisphosphate 1‐kinase activity: K m = 27 μM, and V max = 19 nmol min−1 mg−1.

MCK1 is a novel regulator of myo-inositol phosphate synthase (MIPS) that is required for inhibition of inositol synthesis by the mood stabilizer valproate. [PDF]
PLoS ONE, 2017 Myo-inositol, the precursor of all inositol compounds, is essential for the viability of eukaryotes. Identifying the factors that regulate inositol homeostasis is of obvious importance to understanding cell function and the pathologies underlying ...

The intracellular inositol (pyro)phosphate receptor AtSPX1 reciprocally binds to P1BS DNA
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

Activated Inositol Phosphate, Substrate for Synthesis of Prostaglandylinositol Cyclic Phosphate (Cyclic PIP)-The Key for the Effectiveness of Inositol-Feeding. [PDF]
Int J Mol SciThe natural cyclic AMP antagonist, prostaglandylinositol cyclic phosphate (cyclic PIP), is biosynthesized from prostaglandin E (PGE) and activated inositol phosphate (n-Ins-P), which is synthesized by a particulate rat-liver-enzyme from GTP and a ...

The Role of Inositol Hexakisphosphate Kinase in the Central Nervous System
Biomolecules, 2023 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 ...

Myo- inositol and its metabolites in abiotic stress tolerance in plants [PDF]
Journal of Stress Physiology & Biochemistry, 2022 Myo-inositol (MI) is a sugar-alcohol produced by most plants and animals. 1L-myo-Inositol- 1-phosphate synthase (MIPS) is the rate limiting enzyme that catalyzes the conversion of D-glucose 6- phosphate to 1L-myo-inositol-1-phosphate, the first step in ...

Inositol Signaling in the Basidiomycete Fungus Schizophyllum commune
Journal of Fungi, 2021 Intracellular signaling is conserved in eukaryotes to allow for response to extracellular signals and to regulate development and cellular functions. In fungi, inositol phosphate signaling has been shown to be involved in growth, sexual reproduction, and
