Kcnq4 Potassium Channel Kv7.4 is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
KCNQ4 (Potassium Voltage-Gated Channel Subfamily Q Member 4) encodes the Kv7.4 potassium channel, an important voltage-gated potassium channel expressed primarily in sensory hair cells of the inner ear and certain neurons. This channel is crucial for maintaining the resting membrane potential and regulating neuronal excitability. [1]
