933-1198 2.23e-46

Ion transport protein; This family contains sodium, potassium and calcium ion channels. This family is 6 transmembrane helices in which the last two helices flank a loop which determines ion selectivity. In some sub-families (e.g. Na channels) the domain is repeated four times, whereas in others (e.g. K channels) the protein forms as a tetramer in the membrane.

Ion transport protein; This family contains sodium, potassium and calcium ion channels. This family is 6 transmembrane helices in which the last two helices flank a loop which determines ion selectivity. In some sub-families (e.g. Na channels) the domain is repeated four times, whereas in others (e.g. K channels) the protein forms as a tetramer in the membrane.

1194-1246 7.44e-22

Inactivation gate of the voltage-gated sodium channel alpha subunits; This region is part of the intracellular linker between domains III and IV of the alpha subunits of voltage-gated sodium channels. It is responsible for fast inactivation of the channel and essential for proper physiological function.
