(A) Representative currents recorded from inside-out membrane patches containing Kir6.2[R34A] coexpressed with SUR1. The dashed line indicates zero current. (B) Mean current (in zero ATP) versus time after application of PIP2 for Kir6.2 WT coexpressed with SUR1 and for Kir6.2[R34A] coexpressed with SUR1.
