Atom-by-atom engineering of voltage-gated ion channels: magnified insights into function and pharmacology

J Physiol. 2015 Jun 15;593(12):2627-34. doi: 10.1113/jphysiol.2014.287714. Epub 2015 Mar 13.


Unnatural amino acid incorporation into ion channels has proven to be a valuable approach to interrogate detailed hypotheses arising from atomic resolution structures. In this short review, we provide a brief overview of some of the basic principles and methods for incorporation of unnatural amino acids into proteins. We also review insights into the function and pharmacology of voltage-gated ion channels that have emerged from unnatural amino acid mutagenesis approaches.
