Versatile signaling mechanisms of inositol pyrophosphates
Current Opinion in Chemical Biology, 2022 Inositol pyrophosphates (PP-InsPs) constitute a group of highly charged messengers, which regulate central biological processes in health and disease, such as cellular phosphate and general energy homeostasis. Deciphering the molecular mechanisms underlying PP-InsP-mediated signaling remains a challenge due to the unique properties of these molecules ...

Structural insight into inositol pyrophosphate turnover [PDF]
Advances in Biological Regulation, 2013 The diphosphoinositol polyphosphates ("inositol pyrophosphates"; PP-InsPs) regulate many cellular processes in eukaryotes, including stress responses, apoptosis, vesicle trafficking, cytoskeletal dynamics, exocytosis, telomere maintenance, insulin signaling and neutrophil activation.

mBio, 2023 Inositol pyrophosphate 1,5-IP8 is a signaling molecule that regulates phosphate and polyphosphate homeostasis in the fission yeast Schizosaccharomyces pombe. 1,5-IP8 levels are dictated by a balance between the Asp1 kinase domain that converts 5-IP7 to 1,

Protein pyrophosphorylation: moving forward [PDF]
, 2016 Genetic ablation of inositol pyrophosphate synthesis has established the fundamental importance of this class of molecules to the eukaryote cell. These studies, however, must be complemented by cell biology and biochemical approaches to appreciate the ...

Development of a homogenous high-throughput assay for inositol hexakisphosphate kinase 1 activity. [PDF]
PLoS ONE, 2017 Inositol pyrophosphates have been implicated in a wide range of cellular processes. Inositol hexakisphosphate kinase 1 catalyzes the pyrophosphorylation of inositol hexakisphosphate into inositol 5-diphospho-1,2,3,4,6-pentakisphosphate which is important

Inositol pyrophosphates regulate JMJD2C-dependent histone demethylation. [PDF]
Proc Natl Acad Sci U S A, 2013 Significance Epigenetic modifications of chromatin are emerging as important regulatory mechanisms of many nuclear processes. Numerous proteins have been identified that mediate these modifications in a dynamic manner.

Inositols in Insulin Signaling and Glucose Metabolism [PDF]
, 2018 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

A tale of two inositol trisphosphates. [PDF]
, 2016 Between spring 1982 and autumn 1984 the physiological role of Ins(1,4,5)P3 as a calcium-mobilizing second messenger was first suggested and then experimentally established.
