Expression, purification and functional reconstitution of slack sodium-activated potassium channels.

Yangyang Yan1, Youshan Yang, Shumin Bian, Fred J Sigworth.   

Abstract

The slack (slo2.2) gene codes for a potassium-channel α-subunit of the 6TM voltage-gated channel family. Expression of slack results in Na(+)-activated potassium channel activity in various cell types. We describe the purification and reconstitution of Slack protein and show that the Slack α-subunit alone is sufficient for potassium channel activity activated by sodium ions as assayed in planar bilayer membranes and in membrane vesicles.
