Description
Description
Voltage-gated sodium (NaV) channels allow the inward movement of Na+ ions in response to a change in membrane potential. The voltage-gated pore is formed by homotetramers of the α subunit. In D.mel there is only one α subunit gene, but splicing variants of para exhibit distinct gating properties and conductivities. (Adapted from FBrf0228338).
