Insect toxins with tandem repeats of neurotoxin domains have been found with enhanced receptor avidity. Here, the authors describe a bivalent toxin from remipede venom that targets ryanodine receptors, a rare target for animal venoms.

The canonical mechanistic model explaining potassium channel gating is of a conformational change that alternately dilates and constricts a collar-like intracellular entrance to the pore. It is based on the premise that K+ ions maintain a complete hy

Phenytoin is a hydantoin derivative that is used clinically for the treatment of epilepsy and has been reported to have antiarrhythmic actions on the heart. In a failing heart, the elevated diastolic Ca2+ leak from the sarcoplasmic reticulum can be n

Ion currents through potassium channels are gated. Constriction of the ion conduction pathway at the inner helix bundle, the textbook ‘gate’ of Kir potassium channels, has been shown to be an ineffective permeation control, creating a rift in our

Calmodulin (CaM) is a Ca-binding protein that binds to, and can directly inhibit cardiac ryanodine receptor calcium release channels (RyR2). Animal studies have shown that RyR2 hyperphosphorylation reduces CaM binding to RyR2 in failing hearts, but d

Cyclic calcium release and uptake in heart cells has an important role in heart rhythm and contraction, and it is known that the malregulation of calcium release is a predictor for cardiac arrhythmia. A model of this calcium release process was propo

BACKGROUND: This study examines the use of topical pharmacological agents as a snakebite first aid where slowing venom reaching the circulation prevents systemic toxicity. It is based on the fact that toxin molecules in most snake venoms are large mo

BACKGROUND: Phenytoin has long been used to treat epilepsy and for some time as an antiarrhythmic drug (AAD). It is known that the diastolic calcium leakage through dysfunctional cardiac ryanodine receptors (RyR2) is a mechanism for arrhythmias in he

Here we investigate how ß-adrenergic stimulation of the heart alters regulation of ryanodine receptors (RyRs) by intracellular Ca(2+) and Mg(2+) and the role of these changes in SR Ca(2+) release. RyRs were isolated from rat hearts, perfused in a La
