Electromagnetic gating in ion channels
Journal of Theoretical Biology, 1992There have been many attempts to develop a theoretical explanation of the phenomena of electromagnetic field interactions with biological systems. None of the reported efforts have been entirely successful in accounting for the observed experimental results, in particular with respect to the reports of interactions between extremely low frequency (ELF)

Angewandte Chemie International Edition, 2001
Ion channels are at the heart of many biological processes such as nerve activity and muscle contraction. How are their impressive ion selectivity and highly specialized gating brought about? In recent years, X-ray crystallography and high-resolution electron microscopy, as well as photo-affinity labeling and site-specific mutagenesis techniques in ...

Ligand‐Gated Synthetic Ion Channels
Chemistry – A European Journal, 2005AbstractSupramolecular π‐stack architecture is fundamental in DNA chemistry but absent in biological and synthetic ion channels and pores. Here, a novel rigid‐rod π‐stack architecture is introduced to create synthetic ion channels with characteristics that are at the forefront of rational design, that is, ligand gating by a conformational change of the

Voltage gating of ion channels
Quarterly Reviews of Biophysics, 1994Voltage-gated ion channels are membrane proteins that play a central role in the propagation and transduction of cellular signals (Hille, 1992). Calcium ions entering cells through voltage-gated calcium channels serve as the trigger for neurotransmitter release, muscle contraction, and the release of hormones. Voltage-gated sodium channels initiate the

Ion Channels: Opening the Gate
Science, 1996A recent paper in Science ( 12 Jan., p. 213 ) and two papers in Neuron (H. P. Larsson et al. , in press, and N. Yang et al. , vol. 16, p. 113) demonstrate that a charged portion of the sodium and potassium ion channel (S4)
