HMDBP09082

Secondary Accession Numbers

14826

Name

Sodium channel protein type 3 subunit alpha

Synonyms

Sodium channel protein brain III subunit alpha
Sodium channel protein type III subunit alpha
Voltage-gated sodium channel subtype III
Voltage-gated sodium channel subunit alpha Nav1.3

Gene Name

SCN3A

Protein Type

Unknown

Biological Properties

General Function

Involved in ion channel activity

Specific 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
