sodium channel protein type 3 subunit alpha isoform X8 [Homo sapiens]

Protein Classification

sodium channel protein subunit alpha; ion transporter( domain architecture ID 11999288)

sodium channel protein subunit alpha mediates the voltage-dependent sodium ion permeability of excitable membranes| ion transporter such as a voltage-gated cation channel, which enables the selective translocation of cations such as sodium, calcium, or potassium, across cell membranes

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.

Sodium ion transport-associated; Members of this family contain a region found exclusively in eukaryotic sodium channels or their subunits, many of which are voltage-gated. Members very often also contain between one and four copies of pfam00520 and, less often, one copy of pfam00612.
