scientists proposed the sliding filament theory to explain the molecular mechanisms behind muscle contraction. Within the sarcomere, myosin slides along actin to contract the muscle fiber in a ...

Recent research has expanded our understanding of these mechanisms ... proteins. Myosin Light Chain (MLC): A protein that plays a key role in muscle contraction by interacting with actin filaments.

Numerous motor and structural proteins compose a highly ordered structure known as the sarcomere, the basic unit of muscle contraction in heart and skeletal muscles. Sarcomeric myosin heavy chain ...
