Closed-channel block of BK potassium channels by bbTBA requires partial activation

Blockade of large-conductance Ca(2+)-activated K(+) (BK) channels by the bulky quaternary ammonium compound, N-(4-[benzoyl]benzyl)-N,N,N-tributylammonium (bbTBA), exhibits features consistent with blockade of both closed and open states. Here, we examine block of closed BK channels by bbTBA and how...
