Emerging roles of inositol pyrophosphates in signaling plant phosphorus status and phytohormone signaling [PDF]
Plant and Soil, 2023 Phosphorus (P) is an indispensable macronutrient serving a variety of functions in plants. Inositol pyrophosphates (PP-InsPs) nutrient messengers play vital roles in the signaling of P status and plant growth and development. In this review, we summarize

Inositol pyrophosphates: metabolism and signaling
Cellular and Molecular Life Sciences, 2006Inositol pyrophosphates belong to the diverse family of inositol polyphosphate species that have a range of signaling functions. Since the discovery of inositol pyrophosphates in the early 1990s, enormous progress has been achieved in characterising this class of molecules, linking their biological presence to a wide range of cellular functions ...

Inositol pyrophosphates modulate cell cycle independently of alteration in telomere length [PDF]
Advances in Biological Regulation, 2016 Synthesis of inositol pyrophosphates through activation of Kcs1 plays an important role in the signalling response required for cell cycle progression after mating pheromone arrest. Overexpression of Kcs1 doubled the level of inositol pyrophosphates when

Flux regulation through glycolysis and respiration is balanced by inositol pyrophosphates in yeast [PDF]
Cell, 2023 Although many prokaryotes have glycolysis alternatives, it\u27s considered as the only energy-generating glucose catabolic pathway in eukaryotes. Here, we managed to create a hybrid-glycolysis yeast.

Phosphorylation of Proteins by Inositol Pyrophosphates
Science, 2004The inositol pyrophosphates IP 7 and IP 8 contain highly energetic pyrophosphate bonds. Although implicated in various biologic functions, their molecular sites of action have not been clarified. Using radiolabeled IP 7

Eukaryotic Phosphate Homeostasis: The Inositol Pyrophosphate Perspective [PDF]
Trends in Biochemical Sciences, 2017 Phosphate, as a cellular energy currency, essentially drives most biochemical reactions defining living organisms, and thus its homeostasis must be tightly regulated. Investigation into the role of inositol pyrophosphates (PP-IPs) has provided a novel perspective on the regulation of phosphate homeostasis.

Two inositol hexakisphosphate kinases drive inositol pyrophosphate synthesis in plants [PDF]
Plant Journal, 2014 SummaryInositol pyrophosphates are unique cellular signaling molecules with recently discovered roles in energy sensing and metabolism. Studies in eukaryotes have revealed that these compounds have a rapid turnover, and thus only small amounts accumulate.

Understanding Inositol Pyrophosphates
Science's STKE, 2007Inositol pyrophosphates are relatively poorly understood, highly phosphorylated members of the inositol polyphosphate family. Two studies describe related advances in signaling involving inositol pyrophosphates. Mulugu et al . purified an inositol pyrophosphate synthase from yeast, called Vip1. Lee et al
