Fig. 9. Schematic representation of the myosin interaction sites within the C-terminal region of the MyBPs. The last four domains of MyBP-C and MyBP-H are represented in cartoon style with stippled squares (FnIII modules) and circles (IgI modules). The previously identified myosin interaction domains are listed above the cartoon of the MyBP C-terminus. Interaction sites identified in this study, myosin crosslinking and colocalization domains and the locations they map to are illustrated in the diagram.
