Contribution of polymorphic variation of inositol hexakisphosphate kinase 3 (IP6K3) gene promoter to the susceptibility to late onset Alzheimer's disease [PDF]
Maintenance of electric potential and synaptic transmission are energetically demanding tasks that neuronal metabolism must continually satisfy. Inability to fulfil these energy requirements leads to the development of neurodegenerative disorders ...

PPIP5K1 Suppresses Etoposide-triggered Apoptosis
Inositol hexakisphosphate kinase 2 (IP6K2) potentiates pro-apoptotic signalling and increases the sensitivity of mammalian cells to cytotoxic agents. Diphosphoinositol pentakisphosphate kinase (PPIP5K) generates inositol pyrophosphates (InsPPs) that are ...

Background Inositol pyrophosphates (PP-InsPs) are high-energy cellular molecules involved in different signalling and regulatory responses. Two distinct classes of inositol phosphate kinases responsible for the synthesis of PP-InsPs have been identified ...

First synthetic analogues of diphosphoinositol polyphosphates: interaction with PP-InsP5 kinase [PDF]
We synthesised analogues of diphosphoinositol polyphosphates (PP-InsPs) in which the diphosphate is replaced by an α-phosphonoacetic acid (PA) ester. Structural analysis revealed that 5-PA-InsP5 mimics 5-PP-InsP 5 binding to the kinase domain of PPIP5K2;

Diversification in the inositol tris/tetrakisphosphate kinase (ITPK) family: crystal structure and enzymology of the outlier AtITPK4 [PDF]
Myo-inositol tris/tetrakisphosphate kinases (ITPKs) catalyze diverse phosphotransfer reactions with myo-inositol phosphate and myo-inositol pyrophosphate substrates. However, the lack of structures of nucleotide-coordinated plant ITPKs thwarts a rational

Chemical tools to investigate inositol pyrophosphate protein interactions [PDF]
Die Inositol-Pyrophosphate (PP-InsPs) sind eine ubiquitäre Gruppe hochphosphorylierter eukaryotischer Signalmoleküle. Sie werden mit einer Vielzahl zentraler zellulärer Prozesse in Verbindung gebracht, doch fehlt oft ein detailliertes Verständnis der ...

Analysis of inositol phosphate metabolism by capillary electrophoresis electrospray ionization mass spectrometry [PDF]
The analysis of myo-inositol phosphates (InsPs) and myo-inositol pyrophosphates (PP-InsPs) is a daunting challenge due to the large number of possible isomers, the absence of a chromophore, the high charge density, the low abundance, and the instability ...

Synthetic tools for studying the chemical biology of InsP8 [PDF]
To synthesise stabilised mimics of InsP8, the most phosphorylated inositol phosphate signalling molecule in Nature, we replaced its two diphosphate (PP) groups with either phosphonoacetate (PA) or methylenebisphosphonate (PCP) groups.

Importance of Radioactive Labelling to Elucidate Inositol Polyphosphate Signalling [PDF]
Inositol polyphosphates, in their water-soluble or lipid-bound forms, represent a large and multifaceted family of signalling molecules. Some inositol polyphosphates are well recognised as defining important signal transduction pathways, as in the case ...
