Control of plant phosphate homeostasis by inositol pyrophosphates and the SPX domain

, 2018
Proteins containing a SPX domain are involved in phosphate (Pi) homeostasis, including Pi transport and adaptation to Pi deficiency. The SPX domain harbors a basic surface binding Pi at low affinity and inositol pyrophosphates (PP-InsPs) at high affinity.

Evolution of the SPX gene family and its role in the response mechanism to low phosphorus stress in self-rooted apple stock

BMC Genomics
Background Phosphorus plays a key role in plant adaptation to adversity and plays a positive role in the yield and quality formation of apples. Genes of the SPX domain-containing family are widely involved in the regulation of phosphorus signalling ...

Spx inhibits expression of the SwrA•DegU master flagellar activator in Bacillus subtilis

Journal of Bacteriology
Flagella are trans-envelope nanomachines expressed from genes organized in a complex regulatory hierarchy governed at the highest level by transcription factors called master activators. The master activator of flagellar biosynthesis in Bacillus subtilis

Association between spexin, nutritional status of pregnant women with excessive gestational weight gain, and newborn weight: A cross-sectional study

Clinical Nutrition Open Science
Summary: Introduction: Excessive gestational weight gain (EGWG) is associated with adverse effects on the life of the mother and the neonate. Spexin (SPX) is considered as a new factor involved in glucose homeostasis, body weight and fat metabolism ...

The emerging importance of the SPX domain-containing proteins in phosphate homeostasis

New Phytologist, 2012
Plant growth and development are strongly influenced by the availability of nutrients in the soil solution. Among them, phosphorus (P) is one of the most essential and most limiting macro-elements for plants.

Loss of two families of SPX domain-containing proteins required for vacuolar polyphosphate accumulation coincides with the transition to phosphate storage in green plants

Molecular Plant, 2021
International audiencePhosphorus is an essential nutrient for plants. It is stored as inorganic phosphate (Pi) in the vacuoles of land plants but as inorganic polyphosphate (polyP) in chlorophyte algae.

Transcriptome-Wide Identification and Expression Profiling of SPX Domain-Containing Members in Responses to Phosphorus Deprivation of Pinus massoniana

Forests, 2021
The SPX domain-encoding proteins are believed to play important roles in phosphorus (Pi) homeostasis and signal transduction in plants. However, the overall information and responses of SPXs to phosphorus deficiency in pines, remain undefined.

Structural Basis for YjbH Adaptor-Mediated Recognition of Transcription Factor Spx

Structure, 2019
YjbH is a bacterial adaptor protein required for efficient proteolysis of the RNA polymerase-binding transcription factor Spx by the ClpXP protease. We report the structure of YjbH in complex with Spx.

Exploring the Amino Acid Residue Requirements of the RNA Polymerase (RNAP) α Subunit C-Terminal Domain for Productive Interaction between Spx and RNAP of Bacillus subtilis.

Journal of Bacteriology, 2017
Bacillus subtilis Spx is a global transcriptional regulator that is conserved among Gram-positive bacteria, in which Spx is required for preventing oxidatively induced proteotoxicity.
