KCNAB2 (Potassium Voltage-Gated Channel Subfamily A Regulatory Beta Subunit 2) are Protein Coding genes. 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. Diseases associated with KCNAB2 include Chromosome 1P36 Deletion Syndrome and Episodic Ataxia, Type 1.
