Optimized Protocol for Preservation of Human Platelet Samples for Fluorometric Polyphosphate Quantification

Methods and Protocols, 2023
Platelet polyphosphate (polyP) can be conveniently quantified by exploiting a recent methodological breakthrough using 4′,6-diamidino-2-phenylindole (DAPI). However, the preservation of these biological samples has not yet been standardized.

Polyphosphate, platelets, and coagulation [PDF]

International Journal of Laboratory Hematology, 2015
SummaryWhile we have understood the basic outline of the enzymes and reactions that make up the traditional blood coagulation cascade for many years, recently our appreciation of the complexity of these interactions has greatly increased. This has resulted in unofficial ‘revisions’ of the coagulation cascade to include new amplification pathways and ...

A Schiff base-coated ammonia polyphosphate for improving thermal and fire-retardant properties of unsaturated polyester

, 2023
Despite extensive applications in modern industry, unsaturated polyester resin (UPR) suffers intrinsic flammability, presenting fire threats to both environment and properties.

Xenotropic and polytropic retrovirus receptor 1 regulates procoagulant platelet polyphosphate [PDF]

, 2020
Polyphosphate is a procoagulant inorganic polymer of linear-linked orthophosphate residues. Multiple investigations have established the importance of platelet polyphosphate in blood coagulation; however, the mechanistic details of polyphosphate ...

Pleiotropic effects of PipX, PipY, or RelQ overexpression on growth, cell size, photosynthesis, and polyphosphate accumulation in the cyanobacterium Synechococcus elongatus PCC7942

Frontiers in Microbiology, 2023
The cyanobacterial protein PipY belongs to the Pyridoxal-phosphate (PLP)-binding proteins (PLPBP/COG0325) family of pyridoxal-phosphate-binding proteins, which are represented in all three domains of life.

Polyphosphate Is a Primordial Chaperone [PDF]

Molecular Cell, 2014
Composed of up to 1,000 phospho-anhydride bond-linked phosphate monomers, inorganic polyphosphate (polyP) is one of the most ancient, conserved, and enigmatic molecules in biology. Here we demonstrate that polyP functions as a hitherto unrecognized chaperone.

Polyphosphate strikes back [PDF]

Blood, 2016
In this issue of Blood, Mitchell et al show how platelet polyphosphate (polyP) amplifies the role of factor XII (FXII) as a plasminogen activator. This negatively charged polymer acts as a “molecular adaptor” that concentrates FXII and plasminogen on the surface of fibrin polymers, eventually resulting in plasmin formation (see figure ...

Control of eukaryotic phosphate homeostasis by inositol polyphosphate sensor domains

, 2016
Phosphorus is a macronutrient taken up by cells as inorganic phosphate (P(i)). How cells sense cellular P(i) levels is poorly characterized. Here, we report that SPX domains--which are found in eukaryotic phosphate transporters, signaling proteins, and ...
