Gene Information

human ... ACTA2(59)

General description

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,
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.

Immunogen

Synthetic peptide near the N-terminus of human SMA protein.

Application

Anti-SMA antibody, Rabbit monoclonal has been used in:
  • western blotting
  • immunohistochemistry
  • immunofluorescence

Biochem/physiol Actions

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).

Transforming growth factor-β (TGF-β) induces epithelial-mesenchymal transition (EMT) primarily via a Smad‑dependent mechanism. However, there are few studies available on TGF-β-induced EMT through the activation of non‑canonical pathways. In this study, the Cdc42-interacting protein-4 (CIP4)/partitioning-defective protein 6 (Par6) pathway was investigated in TGF-β1‑stimulated NRK-52E cells. Rat
