Loss of Zn(II) modulator activity in the C132A P2X4R mutant but not the C126A mutant. (A) Representative recordings of 1 μM ATP-gated currents in two P2X4R mutants (C132A and C126A) in the absence or presence of 10 μM Zn(II), 3 μM IVM and joint application of Zn(II) plus IVM. ATP and IVM applications are represented by blue and brown rectangles, respectively. Each set of recordings is derived from a single oocyte expressing either the C132A or the C126A mutants. (B) Statistical analyses of a set of 5 separate oocytes expressing the C132A mutant (open bars) and 4 oocytes expressing the C126A mutant (closed bars) (***p < 0.001); ns (not statistically significant).
