Potassium voltage-gated channel subfamily A member 5; Voltage-gated potassium channel subunit Kv1.5; HK2; HPCN1;
Categories
Primary Antibodies
Clonality
polyclonal
Description
Mediates the voltage-dependent potassium ion permeability of excitable membranes. Assuming opened or closed conformations in response to the voltage difference across the membrane, the protein forms a potassium-selective channel through which potassium ions may pass in accordance with their electrochemical gradient. This channel displays 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.Tamkun M.M., FASEB J. 5:331-337(1991).Philipson L.H., Proc. Natl. Acad. Sci. U.S.A. 88:53-57(1991).Curran M.E., Genomics 12:729-737(1992).

Species
Homo Sapiens (Human)
Specificity
The antibody detects endogenous levels of total KCNA5 protein.
Voltage-gated potassium channel that mediates transmembrane potassium transport in excitable membranes. 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
