A molecular lid mechanism of K+ channelblocker action revealed by a cone peptide

The paper investigates two cone peptides' mechanisms of blocking K+ channels in Drosophila Shaker, revealing a 'molecular lid' mechanism for one peptide.

Pore-modulating toxins exploit inherent slow inactivation to block K+ channels

The paper shows that the toxin Cs1 blocks K+ channels by modulating pore structure through hydrogen bond disruption, leading to asymmetric pore collapse.
