Target Information

Target General Infomation
Target ID
T58741
Former ID
TTDI02461
Target Name
SCN8A sodium channel subunit
Gene Name
SCN8A
Synonyms
Sodium channel protein type 8 subunit alpha; Sodium channel protein type VIII subunit alpha; Voltage-gated sodium channel subunit alpha Nav1.6; SCN8A
Target Type
Research
Function
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.
BioChemical Class
Voltage-gated ion channel
