Regulation of myosin and filamentous actin interaction by tropomyosin is a central feature of contractile events in muscle and nonmuscle cells. However, little is known about molecular interactions within the complex and the trajectory of tropomyosin movement between its "open" and "closed" positions on the actin filament.

Abstract. Actin-myosin interactions play crucial roles in the generation of cellular force and movement. The molecular mechanism involves structural transitions at the interface between actin and myosin's catalytic domain, and within myosin's light chain domain, which contains binding sites for essential (ELC) and regulatory light chains (RLC).

Recently, the association of myosin-like proteins, albeit of somewhat different composition, with the nuclear pore complex has been reported 7. The history of research on actin in the nucleus is the actin-tropomyosin-myosin complex in the rigor (nucleotide-free) state determined by cryo-EM. The pseudoatomic model of the complex, obtained from fitting crystal structures into the map, defines a large actin-myosin-tropomyosin interface. This interface involves two adjacent actin monomers and one tropo- Actomyosin refers to the actin-myosin complex that forms within the cytoskeleton. Actomyosin is inherently contractile, with the myosin motor protein able to pull on actin filaments. Details of Actin-Myosin Crosslinking.
