Polyamine block of MthK potassium channels

J Gen Physiol. 2020 Jul 6;152(7):e202012614. doi: 10.1085/jgp.202012614.

Abstract

Polyamines can modulate membrane excitability by blocking ion flux through ion channels. Suma et al. determined the location of the binding site for polyamines inside a model potassium channel pore.
