Potassium voltage-gated channel subfamily Q member 5 (KCNQ5)

Target
KCNQ5
Molecular classification
Ion channel, Voltage-gated potassium channel
01

Overview

KCNQ5 is a pore-forming subunit of the voltage-gated potassium (Kv) channel family. It plays a crucial role in regulating neuronal excitability by contributing to the M-current. It can form heteromeric channels with other members of its family, notably with KCNQ3. Mutations or dysfunctions in KCNQ family members are linked to neurological disorders.
