Figure 2. (A) Single-channel currents recorded at −60 mV from an inside-out patch excised from an oocyte expressing Kir6.2/SUR1, Kir1.1, or Kir2.1, as indicated. Currents were recorded in a symmetrical 140-mM solution. The dashed line indicates the zero current level. (B) Sequence of the pore loop of Kir6.2 compared with that of some other types of K+ channel. Arrows indicate the mutated residues.
