Antigen Background

Cytoplasmic actins are part of the microfilament system of cytoskeletal proteins.Smooth muscle actin is found in vascular walls, intestinal muscularis mucosae and muscularis propria and in the stroma of various tissues.

It is also reported to be expressed in myofibroblasts and myoepithelial cells, and antibodies to SMA are reported to be a useful tool for the identification of leiomyomas, leiomyosarcomas and pleomorphic adenomas.
