Target sequence recognition by the calmodulin superfamily: implications from light chain binding to the regulatory domain of scallop myosin.

Abstract excerpt

Some of the rules for how members of the calmodulin (CaM) superfamily bind to target peptides are revealed by the crystal structure of the regulatory domain of scallop myosin. The structure shows that the IQ motif of the heavy chain in this invertebrate myosin imposes constraints on both the positioning and conformation of the individual lobes of the light chains. In contrast, analysis of the contact residues in...
