Inositol Pyrophosphates Get the Vip1 Treatment [PDF]
Inositol pyrophosphates are unique signaling molecules implicated in the regulation of diverse cellular processes. Two new studies by Mulugu et al. (2007) and Lee et al. (2007) extend the biological and metabolic diversity of this class of molecules. They identify yeast Vip1 as a new inositol pyrophosphate synthase and show that the products of Vip1 ...

A Role for Inositol Pyrophosphates in the Metabolic Adaptations to Low Phosphate in Arabidopsis [PDF]
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 ...

Inositol pyrophosphates and their unique metabolic complexity: analysis by gel electrophoresis.
BackgroundInositol pyrophosphates are a recently characterized cell signalling molecules responsible for the pyrophosphorylation of protein substrates. Though likely involved in a wide range of cellular functions, the study of inositol pyrophosphates has

Human genome-wide RNAi screen identifies an essential role for inositol pyrophosphates in Type-I interferon response. [PDF]
The pattern recognition receptor RIG-I is critical for Type-I interferon production. However, the global regulation of RIG-I signaling is only partially understood. Using a human genome-wide RNAi-screen, we identified 226 novel regulatory proteins of RIG-

Scalable Chemoenzymatic Synthesis of Inositol Pyrophosphates [PDF]
The inositol pyrophosphates (PP-InsPs) are an important group of cellular messengers that influence a broad range of biological processes. To elucidate the functions of these high-energy metabolites at the biochemical level, access to the purified molecules is required.

Mammalian inositol polyphosphate multikinase synthesizes inositol 1,4,5-trisphosphate and an inositol pyrophosphate [PDF]
Using a consensus sequence in inositol phosphate kinase, we have identified and cloned a 44-kDa mammalian inositol phosphate kinase with broader catalytic capacities than any other member of the family and which we designate mammalian inositol phosphate multikinase (mIPMK).

Can Inositol Pyrophosphates Inform Strategies for Developing Low Phytate Crops?
Inositol pyrophosphates (PP-InsPs) are an emerging class of “high-energy” intracellular signaling molecules, containing one or two diphosphate groups attached to an inositol ring, that are connected with phosphate sensing, jasmonate signaling,
