Actin, Gamma 2
Actin, Gamma 2, encoded by the ACTG2 gene, is a smooth muscle actin found in enteric tissues. Actins are highly conserved proteins that are involved in various types of cell motility, and maintenance of the cytoskeleton. In vertebrates, three main groups of actin isoforms, alpha, beta and gamma have been identified. The alpha actins are found in muscle tissues and are a major constituent of the contractile apparatus. The beta and gamma actins co-exist in most cell types as components of the cytoskeleton, and as mediators of internal cell motility. (NCI Thesaurus/LocusLink)
