N-terminal domain of dystrophin.
Contro-versial experiments have been published on calmodulin binding of dystrophin. In this study, we used recombinant proteins and the techniques of affinity chromatography and ELISA to show that the N-terminal part of dystrophin binds calmodulin specifically in a calcium-dependent manner. The calcium-dependent interaction of calmodulin and dystrophin does not directly regulate binding of actin to dystrophin, but may regulate dystrophin interactions with other associated proteins.
