Mechanism of Ion Permeation in Mammalian Voltage-Gated Sodium Channels
Recent determination of the crystal structures of bacterial voltage-gated sodium (NaV) channels have raised hopes that modeling of the mammalian counterparts could soon be achieved. However, there are substantial differences between the pore domains of the bacterial and mammalian NaV channels, which necessitates careful validation of mammalian homology models constructed from the bacterial NaV ...
متن کاملDiversity of mammalian voltage-gated sodium channels.
A variety of different isoforms of mammalian voltage-gated sodium channels have been identified. These channels can be classified into three different types. Eight type 1 isoforms have been identified in the CNS, PNS, skeletal muscle, and heart. All of these channels have been expressed in exogenous systems, and all of the genes have been mapped. Three type 2 isoforms have been identified in he...
متن کاملMechanism of action of sodium channel blocker insecticides (SCBIs) on insect sodium channels.
Sodium channel blocker insecticides (SCBIs) are a relatively new class of insecticides, with a mechanism of action different from those of other classes of insecticides that target voltage-gated sodium channels. These compounds have no effect at hyperpolarized membrane potentials, but cause a voltage-dependent, nearly irreversible block as the membrane potential is depolarized. The mechanism of...
متن کاملAction of Clathrodin and Analogues on Voltage-Gated Sodium Channels
Clathrodin is a marine alkaloid and believed to be a modulator of voltage-gated sodium (Na(V)) channels. Since there is an urgent need for small molecule Na(V) channel ligands as novel therapeutics, clathrodin could represent an interesting lead compound. Therefore, clathrodin was reinvestigated for its potency and Na(V) channel subtype selectivity. Clathrodin and its synthetic analogues were s...
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...
