Summary of Actin structure and function.. Actin is the most abundant protein in most eukaryotic cells. It is highly conserved and participates in more protein-protein interactions than any known protein.
Muscle proteins: So far we considered actin and myosin. However muscle is more complex and contains a vast array of structural and other proteins. The actin filaments in skeletal and cardiac muscles contain troponin and tropomyosin to control calcium activation and calcium sensitivity.he sliding of the filaments is the result of interactions between myosin molecules in the thick filaments and binding sites on the actin filaments. The myosin molecules have a region which extends away from the backbone of the filaments and binds to actin filaments.
