01

Overview

Potassium channel subfamily KQT member 5 (KCNQ5), also known as Kv7.5, is a voltage-gated potassium channel subunit that plays a critical role in regulating neuronal excitability. It contributes to the M-current, a slow-activating/deactivating potassium conductance crucial for setting the threshold for action potential firing. Mutations in KCNQ5 are associated with neurodevelopmental disorders, intellectual disability, and epilepsy, highlighting its importance in neuronal function. Its activity is modulated by various pharmacological agents, including inhibitors and activators, offering potential therapeutic avenues for related disorders.
