Figure 4. Phosphorylation of Ser193 by casein kinase II.

Figure 4

Purified CaV1.1 channel was phosphorylated by purified casein kinase II as described in Experimental Procedures. The CaVβ1a subunit was isolated by SDS-PAGE and analyzed by MS/MS. Integrated intensities of the peptide peaks representing unphosphoryated CaVβ1a (0P) and phosphorylated CaVβ1a (1P) are illustrated.
