Inositol phosphates in the environment [PDF]

Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 2002
The inositol phosphates are a group of organic phosphorus compounds found widely in the natural environment, but that represent the greatest gap in our understanding of the global phosphorus cycle. They exist as inositols in various states of phosphorylation (bound to between one and six phosphate groups) and isomeric forms (e.g.

A Gas Chromatography-Mass Spectrometry-Based Two Stage Assay for Measurement of in vitro myo-Inositol 3-phosphate Synthase (INO1) Activity

Bio-Protocol, 2015
This method describes an in vitro assay for measuring INO1 enzyme activity (the conversion of glucose 6-phosphate to myo-inositol 3-phosphate) in cell-free extracts. The method was first described for Plasmodium falciparum cells in MacRae et al.

Countercurrent distribution of inositol lipids of plant seeds

Journal of Lipid Research, 1969
The inositol lipids of plant seeds consist of phosphatidyl inositol, the phytoglycolipids, and a previously uncharacterized ceramide-phosphate-polysaccharide. These three species have been separated from each other and from the common glycerophosphatides

Cellular IP₆ Levels Limit HIV Production while Viruses that Cannot Efficiently Package IP₆ Are Attenuated for Infection and Replication [PDF]

, 2019
Summary: HIV-1 hijacks host proteins to promote infection. Here we show that HIV is also dependent upon the host metabolite inositol hexakisphosphate (IP6) for viral production and primary cell replication.

A Role for Inositol Pyrophosphates in the Metabolic Adaptations to Low Phosphate in Arabidopsis

Metabolites, 2021
Phosphate is a major plant macronutrient and low phosphate availability severely limits global crop productivity. In Arabidopsis, a key regulator of the transcriptional response to low phosphate, phosphate starvation response 1 (PHR1), is modulated by a ...

The proppin Bcas3 and its interactor KinkyA localize to the early phagophore and regulate autophagy [PDF]

, 2021
To resolve the signaling mechanisms that mediate the starvation-induced processes of Dictyostelium sporulation and encystation, we performed insertional mutagenesis on cells harboring an mRFP-tagged spore gene.

Inositol pyrophosphates promote the interaction of SPX domains with the coiled-coil motif of PHR transcription factors to regulate plant phosphate homeostasis

Nature Communications, 2021
Plants regulate phosphate homeostasis via the interaction of PHR transcription factors with SPX receptors bound to inositol pyrophosphate signaling molecules.

Pertussis Toxin-sensitive Activation of Phospholipase C by the C5a and fMet-Leu-Phe Receptors [PDF]

, 1996
Signal transduction pathways that mediate C5a and fMet-Leu-Phe (fMLP)-induced pertussis toxin (PTx)-sensitive activation of phospholipase C (PLC) have been investigated using a cotransfection assay system in COS-7 cells.
