Sarcomeres are described as the basic units comprising striated muscles and are comprised of thick (myosin) and thin (actin) filaments and a protein called titin. The filaments slide past each other in muscular contraction and then backwards in muscular relaxation. They are not found in smooth muscles.
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.

Nuclear actin has been identified in chromatin remodelling complexes, nascent In rRNA biogenesis actin and myosin mediate RNA polymerase I transcription.
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). Myosin is responsible for force generation. It is composed of a globular head with both ATP and actin binding sites, and a long tail involved in its polymerization into myosin filaments. The protein complex composed of actin and myosin is sometimes referred to as "actinomyosin".

However, incubating myosin heads (subfragment 1, S1) with filamentous actin (f-actin) produces “decorated actin” in which each myosin head binds to the actin filament in the strong-binding or “rigor” configuration.

The simple crossbridge cycle has been The actin doesn't produce energy, it is like a long fibre. The myosin uses energy to produce force. One myosin molecule with two heads produces about 1.4 picoNewtons (0.0000000000014 Newtons) of force when it changes conformation.

Actin and myosin II form the archetypical molecular motor complex. Myosin II, like all members of the myosin superfamily, is an actin-activated ATPase that uses the energy released when ATP is hydrolyzed to do work. Although we typically associate work with muscle contraction, cell motility and cell division, many nuclear processes require energy.
