Toxins have evolved to target regions of membrane ion channels that underlie ligand binding, gating, or ion permeation, and have thus served as invaluable tools for probing channel structure and function. Here, we describe a peptide toxin from the Earth Tiger tarantula that selectively and irreversibly activates the capsaicin- and heat-sensitive channel, TRPV1. This high-avidity interaction derives...
TRP cation channels function as cellular sensors in uni- and multicellular eukaryotes. Despite intensive study, the mechanisms of TRP channel activation by chemical or physical stimuli remain poorly understood. To identify amino acid residues crucial for TRP channel gating, we developed an unbiased, high-throughput genetic screen in yeast that uncovered rare, constitutively active mutants of the capsaicin...
