Living cells are highly organized, yet they are not assembled using rigid blueprints or by following a predetermined plan.
(A) The basic organization of a sarcomere subregion, showing the centralized location of myosin (A band). Actin and the z discs are shown in red. (B) A conceptual diagram representing the connectivity ...
Understanding how microscopic interactions between proteins in cells produce large-scale organization and asymmetry is a fundamental question in cell biology.
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 ...
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 ...
