Nav1.7 - The Voltage-Gated Sodium Channel full of action
NaV1.7 is a voltage-gated sodium channel and plays a critical role in the generation and conduction of action potentials and is thus important for electrical signaling by most excitable cells. The NaV1.7 channel produces a rapidly activating and inactivating current which is sensitive to the level of tetrodotoxin. It is usually expressed at high levels in two types of neurons, the nociceptive (pain) neurons at dorsal root ganglion (DRG) and trigeminal ganglion, and sympathetic ganglion neurons, which are part of the autonomic (involuntary) nervous system.
