Alpha-smooth muscle actin (alpha-SMA) is found on smooth muscle vessel walls, gut wall, myometrium, myoepithelial cells in breast, and salivary glands. It is abundant in vascular and visceral smooth muscle cells. (1)
Alpha-smooth muscle actin (alpha-SMA) is the actin isoform that predominates within vascular smooth-muscle cells and plays an important role in fibrogenesis.
Actin can be found in two different forms of aggregation, the globular or the fibrillar state, and at least six distinct isoforms occur in vertebrates. The actins exhibit over 90% sequence homology, but each isoform has a unique NH2- terminal sequence. The isoforms are comprised of three alpha actins (skeletal, cardiac, smooth), one beta actin (beta-non-muscle) and two gamma actins (gamma smooth muscle and gamma non-muscle). (2)
