Description_x000D_ General description_x000D_ Smooth muscle actin-alpha (SMA) is a cytoskeleton protein in smooth muscle cells and their derived tumors such as leiomyoma and leiomyosarcoma. It is also expressed in myoepithelial cells of the breast and salivary gland, but not in fibroblasts, striated muscle, and myocardium._x000D_ Smooth muscle actin-α (SMA), also known as α2-smooth muscle actin (ACTA2), is a cytoskeleton protein in smooth muscle cells. It is encoded by the gene mapped to human chromosome 10q23.31. SMA is a vascular smooth muscle specific isoform,_x000D_ Immunogen_x000D_ Synthetic peptide near the N-terminus of human SMA protein._x000D_ Application_x000D_ Anti-SMA antibody, Rabbit monoclonal has been used in:_x000D_ • western blotting_x000D_ • immunohistochemistry_x000D_ • immunofluorescence_x000D_ Physical form_x000D_ 0.1 ml rabbit monoclonal antibody purified by protein A/G in PBS/1% BSA buffer pH 7.6 with less than 0.1% sodium azide._x000D_ Disclaimer_x000D_ Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals._x000D_ Biochem/physiol Actions_x000D_ Smooth muscle actin-α (SMA)/ α2-smooth muscle actin (ACTA2) interacts with β-myosin heavy chain and facilitates vascular smooth muscle cell contraction. The encoded protein regulates c-MET (tyrosine-protein kinase Met) and focal adhesion kinase (FAK) expression in human lung adenocarcinoma cells, which positively and selectively mediates tumor progression. Thus, SMA can be used as a potential prognostic biomarker and/or target for treating metastatic lung adenocarcinoma. Mutation in the gene is associated with the development of patent ductus arteriosus (PDA), bicuspid aortic valve (BAV), iris flocculi, livedo reticularis, cerebrovascular accident (CVA) and stenosis of the aortic vasa vasorum. In addition, variation in the gene expression leads to thoracic aortic aneurysms and dissections (TAAD)._x000D_ Features and Benefits_x000D_ Evaluate our antibodies with complete peace of mind.
