Kcnab2 is a voltage-gated potassium channels (KV) belong to the 6-TM family of potassium channel that also comprises the Ca2+-activated Slo (actually 7-TM) and the Ca2+-activated SK subfamilies. The alpha-subunits contain a single pore-forming region and combine to form tetramers. Voltage-gated potassium (Kv) channels represent the most complex class of voltage-gated ion channels from both functional and structural standpoints. The diverse functions of potassium channels include regulating neurotransmitter release, heart rate, insulin secretion, neuronal excitability, epithelial electrolyte transport, smooth muscle contraction, and cell volume. Four sequence-related potassium channel genes - shaker, shaw, shab, and shal - have been identified in Drosophila, and each has been shown to have human homolog(s). Kcnab2 is one of the beta subunits, which are auxiliary proteins associating with functional Kv-alpha subunits. Alternative splicing of the Kcnab2 gene results in multiple transcript variants encoding distinct isoforms. Diseases associated with KCNAB2 include Chromosome 1P36 Deletion Syndrome.
