Kv1.5 channels are homotetramers of α-pore subunits mainly present in human atrium and pulmonary vasculature. Thus, Kv1.5 is a pharmacological target for cardiovascular diseases. Kvβ1.3 assemblies with Kvα1.5 and modifies its gating and pharmacology. A further knowledge of α-β interactions and pharmacology will lead a better design of new drugs.
