The human heart, often described as the body's engine, is a remarkable organ that tirelessly beats to keep us alive. At the core of this vital organ, intricate processes occur when it contracts, where ...

Molecular motors are nanomachines that convert chemical energy to mechanical work for unidirectional movement. Actomyosin motors have been extensively studied over more than half a century, as ...

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 ...
