Characterization of the mutant proteins. (A) Mobility (Dlat (mean ± SE)) values for the protein populations. Red bars indicate α-isoforms; white bars indicate β-isoforms. βT287D and βE′ have mobility similar to that of the α proteins. (B) Mode (± SE) intensities for the native and mutant GFP-CaMKII fusion protein populations. The bar colors indicate isoforms as in (A).
