A highly polarized excitable cell separates sodium channels from sodium-activated potassium channels by more than a millimeter.
The bioelectrical properties and resulting metabolic demands of electrogenic cells are determined by their morphology and the subcellular localization of ion channels. The electric organ cells (electrocytes) of the electric fish Eigenmannia virescens generate action potentials (APs) with Na(+) currents >10 μA and repolarize the AP with Na(+)-activated K(+) (KNa) channels. To better understand t...

30 The bioelectrical properties and resulting metabolic demands of electrogenic cells are 31 determined by their morphology and the subcellular localization of ion channels. The electric 32 organ cells (electrocytes) of the electric fish Eigenmannia virescens generate action potentials 33 (APs) with Na currents >10 microamperes and repolarize the AP with Na-activated K (KNa) 34 channels. To bet...
متن کاملSlack, Slick, and Sodium-Activated Potassium Channels
The Slack and Slick genes encode potassium channels that are very widely expressed in the central nervous system. These channels are activated by elevations in intracellular sodium, such as those that occur during trains of one or more action potentials, or following activation of non-selective cationic neurotransmitter receptors such as AMPA receptors. This review covers the cellular and molec...
متن کاملVoltage-Gated Sodium Channels Modulation by Bothutous Schach Scorpion Venom
Buthotus schach is one of the dangers scorpion in Iran that belong to the Buthidae family. Toxins are existing in venom scorpion, modulate the ion channels by blocking or opening the pore of the channel or by altering the voltage gating and useful as pharmacological tools. In the present study, we investigated the effect of venom and its obtained fractions by gel filtrations on electrophysiolog...
