Multiple Inositol Polyphosphate Phosphatase Compartmentalization Separates Inositol Phosphate Metabolism from Inositol Lipid Signaling [PDF]
Multiple inositol polyphosphate phosphatase (MINPP1) is an enigmatic enzyme that is responsible for the metabolism of inositol hexakisphosphate (InsP6) and inositol 1,3,4,5,6 pentakisphosphate (Ins(1,3,4,5,6)P5 in mammalian cells, despite being ...

Inositols in Insulin Signaling and Glucose Metabolism [PDF]
In the past decades, both the importance of inositol for human health and the complex interaction between glucose and inositol have been the subject of increasing consideration. Glucose has been shown to interfere with cellular transmembrane transport of

Phytase dose-dependent response of kidney inositol phosphate levels in poultry [PDF]
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 ...

Role of Inositols and Inositol Phosphates in Energy Metabolism [PDF]
Recently, inositols, especially myo-inositol and inositol hexakisphosphate, also known as phytic acid or IP6, with their biological activities received much attention for their role in multiple health beneficial effects.

Preliminary Investigation of Myo-Inositol Phosphates Produced by ASUIA279 Phytase on MCF-7 Cancer Cells [PDF]
Phytate or myo-inositol hexakisphosphates (IP6) is widely distributed in plants like rice brans. The production of myo-inositol phosphate intermediates has received much attention due to the remarkable potential health benefits offered by the compounds ...

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

Inositol phosphate multikinase dependent transcriptional control. [PDF]
Production of lipid-derived inositol phosphates including IP4 and IP5 is an evolutionarily conserved process essential for cellular adaptive responses that is dependent on both phospholipase C and the inositol phosphate multikinase Ipk2 (also known as Arg82 and IPMK). Studies of Ipk2, along with Arg82 prior to demonstrating its IP kinase activity, have

A Solanum tuberosum inositol phosphate kinase (StITPK1) displaying inositol phosphate–inositol phosphate and inositol phosphate–ADP phosphotransferase activities [PDF]
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.
