Potassium Voltage Gated Channel Subfamily H, Member 5 (KCNH5)

Voltage-gated potassium (Kv) channels represent the most complex class of voltage-gated ion channels from both functional and structural standpoints. Their diverse functions include regulating neurotransmitter release, heart rate, insulin secretion, neuronal excitability, epithelial electrolyte transport, smooth muscle contraction, and cell volume.

KCNH5 encodes a member of the potassium channel, voltage-gated, subfamily H. This member is a pore-forming (alpha) subunit of a voltage-gated non-inactivating delayed rectifier potassium channel. This gene is not expressed in differentiating myoblasts. Alternative splicing results in three transcript variants encoding distinct isoforms.Detected in brain, skeletal muscle, heart, placenta, lung and liver, and at low levels in kidney.
