SYNONYMS

Voltage-gatedpotassium channel subunit Kv1.5; Voltage-gated potassium channel subunit Kv1.5; Voltage-gated potassium channel HK2; Potassium voltage-gated channel subfamily A member 5; Potassium channel Kv1.5; HPCN1; HK2; 02-Sensitive Potassium Channel Kv1.5

FUNCTION

Forms tetrameric potassium-selective channels through which potassium ions pass in accordance with their electrochemical gradient. The channel alternates between opened and closed conformations in response to the voltage difference across the membrane. Can form functional homotetrameric channels and heterotetrameric channels that contain variable proportions of KCNA1, KCNA2, KCNA4, KCNA5, and possibly other family members as well; channel properties depend on the type of alpha subunits that are part of the channel. Channel properties are modulated by cytoplasmic beta subunits that regulate the subcellular location of the alpha subunits and promote rapid inactivation. Homotetrameric channels display rapid activation and slow inactivation. May play a role in regulating the secretion of insulin in normal pancreatic islets. Isoform 2 exhibits a voltage-dependent recovery from inactivation and an excessive cumulative inactivation. Voltage-gated potassium channel that mediates transmembrane potassium transport in excitable membranes.
