On the role of ball and chain interactions in recovery from the inactivation of the shaker potassium channel.

Przemysław Borys1, Zbigniew J Grzywna.   

Abstract

We describe a new factor in the recovery from inactivation in the ball and chain model. We propose a model in which the tension from the chain may help pull the ball away from its binding site, reducing the duration of the inactivation period. A corresponding model was built and analysed.
