Divergent Roles of mGlu2 and mGlu3 Receptors in Amyloid‐β Production and Cognitive Dysfunctions in Alzheimer's Disease

Advanced Science, EarlyView.
This study explores the opposing effects of the mGluR2 and mGluR3 receptors on amyloid precursor protein processing. mGluR2 promotes amyloidogenic cleavage, while mGluR3 favors non‐amyloidogenic pathways. Using a brain‐penetrant nanobody as a mGluR2 positive allosteric modulator, the study uncovers how its chronic activation aggravates amyloid‐β burden

Protein pyrophosphorylation by inositol pyrophosphates is a posttranslational event [PDF]

Proceedings of the National Academy of Sciences, 2007
In a previous study, we showed that the inositol pyrophosphate diphosphoinositol pentakisphosphate (IP 7 ) physiologically phosphorylates mammalian and yeast proteins. We now report that this phosphate transfer reflects pyrophosphorylation.

Proteome Analysis of Corynebacterium diphtheriae–Macrophage Interaction

PROTEOMICS, EarlyView.
ABSTRACT Contact of Corynebacterium diphtheriae with macrophages induces adaptations on both bacterial and cellular sides. The study presented here was aiming to shed light on the simultaneous intracellular adaptation of the bacteria and changes in the proteome of the phagocytes in response to the internalization of C. diphtheriae.

Arabidopsis inositol polyphosphate kinase activities regulate COP9 deneddylation functions in phosphate homeostasis

Journal of Integrative Plant Biology, EarlyView.
Plant phosphate (Pi) homeostasis relies on coordinated activities of the inositol polyphosphate kinases IPK1 and ITPK1, which balance localized InsP7 biosynthesis to control COP9 signalosome (CSN)‐dependent deneddylation of cullin 1 (CUL1). Perturbation of this equilibrium affects the stability of SPX4, a key negative regulator of phosphate starvation ...

Inositol Pyrophosphate-Controlled Kinetochore Architecture and Mitotic Entry in S. pombe

Journal of Fungi, 2022
Inositol pyrophosphates (IPPs) comprise a specific class of signaling molecules that regulate central biological processes in eukaryotes. The conserved Vip1/PPIP5K family controls intracellular IP8 levels, the highest phosphorylated form of IPPs present ...

SlMED25‐SlPHR3‐SlSPX2 module fine‐tunes SlPHR3‐mediated transcriptional activation of phosphate starvation response in tomato

Journal of Integrative Plant Biology, EarlyView.
The Mediator subunit SlMED25 and the co‐repressor SlSPX2 competitively bind the N‐terminal domain of the phosphate starvation response transcription factor SlPHR3 in tomato to form a sensitive molecular switch, which dynamically modulates phosphate starvation responses and maintains phosphate homeostasis, offering valuable targets for breeding low ...

Two inositol hexakisphosphate kinases drive inositol pyrophosphate synthesis in plants [PDF]

The 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.

Emerging roles of inositol pyrophosphates in signaling plant phosphorus status and phytohormone signaling [PDF]

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

Strigolactone‐mediated architecture regulation and stress resilience: Insights and innovations for crop breeding

Journal of Integrative Plant Biology, EarlyView.
This review summarizes the discovery, biosynthesis, and transport of strigolactone, and the D14‐D3/MAX2‐D53/SMXLs signaling module. It highlights diverse roles of strigolactone in plant architecture, stress responses, and crop breeding, including species‐specific functions, hormonal crosstalk, and agricultural applications.
