What is the function of this protein?
This protein 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 (PubMed:11834499, PubMed:23420830).  It is a tetrodotoxin-resistant Na(+) channel isoform.  This channel is responsible for the initial upstroke of the action potential.  Channel inactivation is regulated by intracellular calcium levels (By similarity).
What are the official names of this protein?
Sodium channel protein type 5 subunit alpha, Sodium channel protein cardiac muscle subunit alpha, Sodium channel protein type V subunit alpha, Voltage-gated sodium channel subunit alpha Nav1.5, mH1.
What is the protein family that this protein belongs to?
Belongs to the sodium channel (TC 1.A.1.10) family. Nav1.5/SCN5A subfamily.
What are the subcellular locations of this protein?
Cell membrane; Multi-pass membrane protein. Cytoplasm, perinuclear region. Cell membrane, sarcolemma, T-tubule. Note=RANGRF promotes trafficking to the cell membrane.
