Abstract:Acid-sensing ion channels (ASICs) are trimeric proton-gated cation channels that contribute to fast synaptic transmission. Pharmacological inhibition of ASIC1a has been shown to reduce neurotoxicity and infarct volumes during stroke. The cysteine knot toxin Psalmotoxin-1 (PcTx1) is one of the most potent and selective inhibitors of ASIC1a. PcTx1 binds at the subunit interface, but both the stoichiometric requirements and the dynamics of the conformational consequences of the ion channel-peptide interaction rem… Show more
