Potassium voltage-gated channel shaker-related subfamily member 3 also known as KCNA3 or Kv1.3 is a protein that in humans is encoded by the KCNA3 gene.Potassium 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.
