    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.
