SCN8A Mediates the voltage-dependent sodium ion permeability of excitable membranes. Assuming opened or closed conformations in response to the voltage difference across the membrane, the protein forms a sodium-selective channel through which Na(+) ions may pass in accordance with their electrochemical gradient. In macrophages and melanoma cells, isoform 5 may participate in the control of podosome and invadopodia formation. Belongs to the sodium channel (TC 1.A.1.10) family. Nav1.6/SCN8A subfamily. Isoform 5 is expressed in non-neuronal tissues, such as monocytes/macrophages. 5 alternatively spliced human isoforms have been reported.
