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. 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). This gene encodes a member of the potassium channel,;voltage-gated, shab-related subfamily. This member is a delayed rectifier potassium channel. The gene is expressed in;gastrointestinal smooth muscle cells.
