Functional characteristics of mutant and wild-type receptors. Values for peak current, steady-state current, and steady-state to peak ratio are presented as mean ± SEM (N). While no significant effect in peak current amplitude was observed, one-way ANOVA did reveal a significant overall effect in steady-state current amplitude and steady-state to peak ratio (p = 0.032, p = 0.034 respectively). Dunnett’s post-hoc testing, however, demonstrated no significant effect between pair-wise comparisons of wild-type and mutant receptors.
