Proceedings of the National Academy of Sciences of the United States of America, Vol. 90, No. 6 (Mar. 15, 1993), pp. 2127-2131 (5 pages) Amino acid residues D24/D25, E99/E100, E360/E361, and D363/E364 ...

Skeletal and heart muscles contract and relax upon sliding of parallel filaments of the proteins myosin and actin. Nebulin, another long slender protein, which is present only in skeletal muscle, ...

The sliding movement of the actin–myosin protein conjugate responsible for contracting muscles can be inhibited using a dendrimer that glues them together. Muscles contract because of the concerted ...

Actomyosin is a protein complex composed of actin and myosin. It is found in muscle fibers where it plays a role in muscle contraction. Actin is one of the most abundant proteins in eukaryotes. It ...

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 ...

Cells use the polymerization of actin alone to create some types of movement, but many other forms of movement require interplay between actin and an enzyme called ...
