Voltage-Gated Ion Channel

Voltage-Gated Ion Channel

A family of membrane-spanning protein channels whose opening or closing is influenced by membrane voltage and whose ion selectivity depends on channel structure.

Overview

EXPLORE BY LEVEL

Voltage-gated ion channels are protein doors in cell membranes. Changes in voltage can alter whether a channel is open, allowing particular ions to cross.

Channel behavior is isoform-, compartment-, and state-dependent, with modulation by auxiliary subunits, lipids, phosphorylation, and disease variants. This family-level record does not represent one channel subtype.
