Potassium voltage-gated channel subfamily A member 6 (KCNA6)

Voltage-gated potassium channel that mediates transmembrane potassium transport in excitable membranes. Types tetrameric potassium-selective channels through which potassium ions pass in accordance with their electrochemical gradient (PubMed:2347305, PubMed:14575698).

The channel alternates between opened and closed conformations in response to the voltage difference across the membrane (PubMed:2347305, PubMed:14575698). Can form operational homotetrameric channels and heterotetrameric channels which contain varying proportions of KCNA1, KCNA2, KCNA4, KCNA6, and possibly other family members too; channel properties depend on the type of alpha subunits which are part of the channel (By similarity).
