CRYSTAL STRUCTURE OF CALCIUM/CALMODULIN-DEPENDENT PROTEIN KINASE
Overview
We report the crystal structure of the 143 residue association domain of, Ca(2+)/calmodulin-dependent protein kinase II (CaMKII). The association, domain forms a hub-like assembly, composed of two rings of seven protomers, each, which are stacked head to head and held together by extensive, interfaces. The tetradecameric organization of the assembly was confirmed, by analytical ultracentrifugation and multiangle light scattering., Individual protomers form wedge-shaped structures from which N-terminal, helical segments that connect to the kinase domain extend toward the, equatorial plane of the assembly, consistent with the arrangement of the, kinase domains in a second outer ring. A deep and highly conserved pocket, present within the association domain may serve as a docking site for, proteins that interact with CaMKII.
