Background | The two major cytoskeletal proteins implicated in cell motility are actin and myosin. Actin and myosin are constituents of many cell types and are involved in a myriad of cellular processes including locomotion, secretion, cytoplasmic streaming, phagocytosis and cytokinesis. Although actin is one of the most conserved eukaryotic proteins, it is expressed in mammals and birds as at least six isoforms characterized by electrophoresis and amino acid sequence analysis. Four of them represent the differentiation markers of muscle tissues and two are found in nearly all cells. There are three a-actins (a-skeletal, a-cardiac and a-smooth muscle), one b-actin (b-non-muscle), and two g-actins (g-smooth muscle and g-non-muscle). Actin isoforms show >90% overall sequence homology, but only 50-60% homology in their 18 N-terminal residues. The N-terminal region of actin appears to be a major antigenic region, and may be involved in the interaction of actin with other proteins such as myosin. The actin in cells of various species and tissues are very similar in their immunological and physical properties. As a consequence, it is difficult to produce antisera to this protein. The availability of monoclonal antibody to actin provides a specific and useful tool in studying actin structure and function and in probing binding sites of actin-binding proteins |
