J Cell Biol. 2001 May 14;153(4):699-708. doi: 10.1083/jcb.153.4.699. PMID: 11352932; PMCID: PMC2192391.
Abstract Ryanodine receptors (RyRs), intracellular calcium release channels required for cardiac and skeletal muscle contraction, are macromolecular complexes that include kinases and phosphatases. Phosphorylation/dephosphorylation plays a key role in regulating the function of many ion channels, including RyRs. However, the mechanism by which kinases and phosphatases are targeted to ion channels is not well understood.…

p-Phenylenediamine (PPD) is a derivative of aniline used in kevlar, hair dye and henna substitutions among other things, the derivatives of which are used in antiozonants among other horrors
p-Phenylenediamine (PPD) is an organic compound with the formula C6H4(NH2)2. This derivative of aniline is a white solid, but samples can darken due to air oxidation.It is mainly used as a component of engineering polymers and composites like kevlar. It is also an ingredient in hair dyes and is occasionally used as a substitute for henna. Production PPD is produced via three routes. Most commonly, 4-nitrochlorobenzene is treated…

Ryania speciosa, Ryanodine and Ryanoids
Ryania speciosa is a species of plant in the family Salicaceae. The species is significant partly because the ryanoid insecticides are derived from, and have the same mode of action as the alkaloid ryanodine, which was originally extracted from this South American plant, which is also used as a piscicide (fish poison).
