Binding of defined AM(37–52)
variants to purified MBP-RAMP-CLR
ECD fusion proteins. (A, B) Scatter plot of pKI values from competition FP assays for (A) previously reported,
rationally designed AM variants34 or (B)
new AM variants incorporating library-identified substitutions. Numbers
below the x-axis signify the RAMP1, -2, or -3 complexes.
(C) Representative competition binding curves for two key variants
compared to wild-type. See Table S1 for
pKI values with SEM, selectivity comparisons,
and associated statistical analyses.
