Application
Anthopleurin-A is a toxin used to study the gating mechanisms of sodium channels. Anthopleurin-A slows the repolarization phase of nerve and muscle action potentials by inactivating the sodium channel.
Biochem/physiol Actions
Anthopleurin-A slows the repolarization phase of nerve and muscle action potentials by inactivating the sodium channel. Anthopleurin-A shows a preference towards cardiac channels over the neuronal sodium channels. It is a toxin used to study the gating mechanisms of sodium channels.
Shown to have inotropic effects and not chronotropic effects on mammalian heart preparations.
General description
Synthetic peptide toxin that was originally isolated from the sea anemone, Anthopleura xanthogrammica.
Synthetic peptide toxin.

We have previously developed a canine in vivo model of the long QT syndrome (LQTS) using the neurotoxin anthopleurin A (AP-A), which acts by slowing sodium channel inactivation. The recent discovery of a genetic mutation in the cardiac sodium channel
