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… Read more.

Chrysolina beetles, including Chrysolina coerulans, have cardiac glycosides (including xylose) in their defensive glands
The defensive secretions of some chrysomelid beetles belonging to the genera Chrysolina, Chrysochloa, and Dlochrysa contain complex mixtures of cardenolides. The spectral data for some of these compounds suggest that… Read more.

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… Read more.
