Myosin in muscles behaves in a unique way, which might explain why muscles have such strong contractile power. A cartoon showing the asymmetry in the weak binding between myosin and actin that biases ...

This results in calcium rushing into the muscle, allowing actin and myosin to spring into action. Smooth muscle cells can be activated by neuronal signaling or by hormones.

When myosin pulls actin filaments together, the sarcomere length is reduced. In non-muscle and smooth muscle cells, actomyosin is not organized into sarcomeres.

The molecular interaction between smooth muscle (SM) myosin and actin in the corpus cavernosum (CC) determines the erectile state of the penis. A key mechanism regulating this interaction and ...

While their functions are diverse, myosins are similar in structure. NMII is so much like cardiac myosin, which keeps the ...

Characterization of the myosin light chain kinase from smooth muscle as an actin-binding protein that assembles actin filaments in vitro. Biochim. Biophys Acta 1999; 1450 :12–14.

In addition, more than 90 percent of the total volume of a skeletal muscle cell is composed of muscle proteins, including the contractile proteins actin and myosin. When a muscle cell is activated ...
