Actin is a protein found in the cytoskeleton of all higher organisms and is involved in cell movement. Antibodies can react against actin, and there are three main groups in vertebrate cells. Actin antibodies are used in laboratory research and can be associated with autoimmune diseases. They are also used as controls in experiments and […]
Actin is a protein found in all living things that contributes to the cytoskeleton and muscle contraction. The sliding filament theory explains how actin and myosin filaments slide past each other, shortening the sarcomere and causing muscle contraction. ATP is necessary for this process, and tropomyosin can prevent muscle contraction by blocking binding sites. The […]
