Voltage-Gated Sodium Channel (Non-Selective) (VGSC)

Target
VGSC
Molecular classification
Ion channel, Voltage-gated ion channel
01

Overview

Voltage-gated sodium channels are integral membrane proteins that enable the rapid influx of sodium ions into cells in response to changes in membrane potential. This process is essential for the initiation and propagation of action potentials in excitable tissues. The term "non-selective" here typically refers to channels that, while primarily selective for sodium, may also allow passage of other cations under certain conditions or experimental manipulations.
