structure of iGluRs showing the S1 and S2 segments in turquoise
and pink, respectively. “Cut” and “link” denote the
edges of the S1S2 construct.(B) K[D] for ^3H-AMPA binding was
24.8 ± 1.8 nM.(C) IC[50] for displacement of ^3H-AMPA by
glutamate, kainate, and DNQX were 821 nM, 14.5 μM, and 998 nM,
respectively.
