Interaction of the GPV cytoplasmic peptide and calmodulin.
Nondenaturing gel shift of calmodulin (0.3 nmol) in the presence of increasing concentrations of the GPV synthetic peptide, based on K529–G544. Upper and lower panels are in the presence of 1 mM Ca++ or 10 mM EGTA, respectively. Gels were stained with Coomassie blue.
