Abstract
Animal venoms represent a rich source of pharmacologically active peptides that interact with ion channels. In their Communication on page 9306 ff., H. Zhang, R. A. Lerner et al. describe an autocrine‐based method to select functional venom peptides from their vast repertoire in nature. This method allows about 100 million different venoms to be studied in a single experiment, and its utility was demonstrated by the discovery of novel Kv1.3 channel blockers from a natural venom peptide library.
