Actins are highly conserved proteins involved in cell motility, structure and integrity. Actin has been found to be expressed in at least six isomeric forms. It is expressed in heart and skeletal striated muscle tissue, and in certain smooth muscle tissues, regulating contractile potentials for these cells. It is also expressed in the cytoplasm of non-muscle cells, functioning to control cell structure and motility. Smooth Muscle Actin is predominantly located in the cytoplasm, where dynamic filaments form that are essential for various cellular processes, including motility, division, and intracellular transport. Smooth Muscle Actin′s ability to polymerize and depolymerize allows cells to adapt their shape and movement in response to external stimuli, which is particularly important in smooth muscle contraction and relaxation.
