Actins are cytoskeletal proteins that are involved in cell motility and are universally expressed by, and highly conserved in, all eukaryotic cells. Most cell types express the beta and gamma actins, which are involved in internal cell motility. The alpha actins are found mainly in muscle tissues where they comprise part of the contractile apparatus.
Strong cytoplasmic reactivity for Smooth Muscle Actin is seen in the smooth muscle layers and vascular walls of this appendix specimen.
