Figure 2. Functional characterization of the Gly312 hinge in the 2-APB response of TREK-2 channels.
(A) Sequence alignment of the M4 region of indicated channels. The locations of Glycine hinge are indicated. (B) Exemplar current-time recordings from oocytes expressing the WT TREK-2 channels and G312A in the presence of 100 μM 2-APB. (C) Comparative analysis of the dose-response curves evoked by 2-APB between TREK-2 and G312A.
