Schematic diagram of the residue contacts (<4.5 Å distance) of the Cav I N-terminal region (T1609–1623; left column) with primarily the N-lobe of CaM I (residues in tan) and Cav II C-terminal region (1633–1649; right column) with mainly the C-lobe of CaM I (residues in light blue). The total contacts of nonhydrogen atoms between Cav I N-terminal region and CaM I N-lobe/C-lobe is ≈200 and that between Cav II C-terminal region and CaM I C-lobe/N-lobe is ≈260. Similar contacts are made with CaM II lobes.
