      eLife assessment

      This valuable study describes an investigation of the properties of two heterologously-expressed Nav1.4 channels, with mutations close to the selectivity filter found in tetrodotoxin(TTX)-resistant snakes. The authors studied these mutants by electrophysiological methods, assessed the muscle properties of two types of snakes bearing these mutations, and built homology models of the channels to hypothesize a molecular explanation of the altered channel properties. The methods employed and the results are generally solid, although some aspects would benefit from additional experiments and a more nuanced discussion.
