Ion Channels

Voltage Gated

The majority of ion channels fall into two broad categories: voltage-gated ion channels (VGIC) and ligand-gated ion channels (LGIC). Members of the VGIC superfamily are usually closed at the resting potential of the cell. A change in the membrane potential causes conformational changes that result in the opening of the pore (voltage-dependent activation), which may be followed by a transitional conformational change (inactivation) to an inactivated state.1 The VGIC superfamily includes calcium channels, chloride channels, potassium channels and sodium channels. Other, smaller categories exist, such as the vanilloid (TRP) receptors, the ATP-gated channels, the cyclic nucleotide-gated channels (CNG) and aquaporins (water channels).
