Immunogen Cytoskeletal extract of Chicken gizzard
Clone R4A
Isotype IgG1
Specificity This antibody is specific for Smoothelin. Reactive with a novel cytoskeletal protein specific for smooth muscle cells: smoothelin. In Western Blot 2 Molecular weight isoforms are detected: 59 kDa isoform specific to visceral SMC (Smoothelin A) and 100 kDa isoform in vascular SMC (Smoothelin B). The antibody is very useful for characterization of atherosclerotic lesions. The antibody is useful tool to monitor SMC differentiation. Confocal scanning laser microscopy of tissue sections and cells in culture showed a filamentous organization of smoothelin co-localizing with actin stress fibers.

Alternative Name Smoothelin (SMTN Antibody Abstract)
Background Smoothelin is a constituent of the smooth muscle cell (SMC) cytoskeleton. Antibodies directed to smoothelin are useful tools to monitor SMC differentiation. Smoothelin is exclusively expressed in fully differentiated (contractile) SMCs. RNA and protein analyses revealed a broad species distribution of this protein. Cells with SMC-like characteristics, such as myofibroblasts and myoepithelial cells, as well as skeletal and cardiac muscle do not contain smoothelin. Confocal scanning laser microscopy of tissue sections and cells in culture show a filamentous organization of smoothelin colocalizing with actin stress fibers. In immunoblots two molecular weight isoforms are detected i.e. a 59 kDa isoform specific for visceral SMC (smoothelin A), and an isoform with a molecular weight of approximately 100 kDa in vascular SMC (smoothelin B). Human smoothelin is encoded by a single copy gene which is located on chromosome 22.Synonyms: SMSMO, SMTN
