The kinetics of voltage-gated ion channels
Quarterly Reviews of Biophysics, 1994When Hodgkin & Huxley (1952) first embarked on the analysis of their voltageclamp data on the ionic currents in the squid giant axon, they hoped to be able to deduce a mechanism from it, but it soon became clear that the electrical data would by themselves yield only very general information about the class of system likely to be involved.

Voltage Gated Ion Channels and Sleep
The Journal of Membrane BiologyIon channels are integral components of the nervous system, playing a pivotal role in shaping membrane potential, neuronal excitability, synaptic transmission and plasticity. Dysfunction in these channels, such as improper expression or localization, can lead to irregular neuronal excitability and synaptic communication, which may manifest as various ...

Structure and Function of Voltage-Gated Ion Channels
Annual Review of Biochemistry, 1993The principal subunits of the voltage-gated Na+, Ca2+ and K+ channels are members of a related gene family and are functionally autonomous in voltage-dependent activation, ion conductance and inactivation. In this article, recent work locating the structural elements that are responsible for these three basic functions of the voltage-gated ion channels

Structure and Function of Voltage-Gated Ion Channels
Naturwissenschaften, 1998Voltage-gated ion channels are key molecules for the generation of electrical signals in cells. They are integral membrane proteins which are activated by a depolarized membrane potential resulting in a conformational change, allowing ions to permeate.

Structure and Modulation of Voltage‐Gated Ion Channels
Annals of the New York Academy of Sciences, 1991The depolarizing phase of the action potential in most excitable cells results from an initial increase in sodium permeability mediated by voltage-gated sodium channels followed by a more prolonged increase in calcium permeability mediated by voltage-gated calcium channels. Repolarization is then caused by activation of voltage-gated potassium channels.

Diseases caused by voltage-gated ion channels
Molecular Aspects of Medicine, 1997Ion channels regulate the transfer of ions between the outer and the inner surface of the cell membrane. The opening of ion channels may be triggered by the binding of a ligand or variations in the membrane potential. Voltage-gated ion channels are an important class of such channels, that are involved in the generation and propagation of action ...

Voltage-Gated Ion Channels and Hereditary Disease
Physiological Reviews, 1999By the introduction of technological advancement in methods of structural analysis, electronics, and recombinant DNA techniques, research in physiology has become molecular. Additionally, focus of interest has been moving away from classical physiology to become increasingly centered on mechanisms of disease.

Molecular pathophysiology of voltage-gated ion channels
1996In addition to the clarification of the pathology of a whole group of hereditary diseases, the study of the consequences of these mutations at the levels of the whole system (patient), organ and cells (excised muscle specimens), and of the channel proteins has taught us that our current opinions on channel structure-function relations are far from ...

The moving parts of voltage-gated ion channels
Quarterly Reviews of Biophysics, 1998Ion channels, like many other proteins, have moving parts that perform useful functions. The channel proteins contain an aqueous, ion-selective pore that crosses the plasma membrane, and they use a number of distinct ‘gating’ mechanisms to open and close this pore in response to biological stimuli such as the binding of a ligand or a change in the ...

Both voltage-gated and ligand-gated ion channels are large protein molecules, as is the sodium pump Na,K-ATPase. In recent years the primary structure of a number of them has been determined, and by combining this information with the biophysical evidence, major advances have been made in our understanding of how they work at the molecular and ...
