DOI: 10.1016/j.bpj.2021.08.015
Abstract: The activation of voltage-dependent ion channels is associated with the movement of gating charges, that give rise to gating currents. Although gating currents from a single channel are too small to be detected, analysis of… read more here.

DOI: 10.1073/pnas.1816724116
Abstract: Significance Hyperpolarization-activated, cyclic nucleotide-gated (HCN) channels show an inverted voltage response compared with virtually all other voltage-gated channels, opening on hyperpolarization rather than depolarization. Although the structure of the HCN1 channel was recently solved, the… read more here.
