一般描述
Matrix Metalloproteinase-2 (MMP-2) is a member of the matrix metalloproteinase (MMP) family of proteins. MMPs participate in the breakdown of extracellular matrix in normal physiological processes like embryonic development, reproduction, and tissue remodeling, as well as in disease processes such as arthritis and metastasis. MMP-2 cleaves many substrates, including extracellular matrix components (collagens, fibronectin, and elastin), soluble metabolic mediators (e.g., apolipoproteins), secreted and extracellular matrix-anchored growth factors, and cytokines.
Along with MMP-9, MMP-2 is involved many pathophysiological processes, including leukocyte migration from the circulation into the tissue during inflammation, Chagas′ Cardiomyopathy, heart failure and chronic kidney disease. MMP-2 thus may be regarded as a potential therapeutic target.
As with most MMPs, MMP-2 is secreted as an inactive pro-protein, which becomes activated when cleaved by extracellular proteinases. This product was pre-activated in vitro using 4-aminophenylmercuric acetate (APMA). Thus, it is active and ready for use. The highly toxic APMA was removed from the final preparation.
This product is expressed in human HEK 293 cells as a glycoprotein with a calculated molecular mass of 72 kDa (amino acids 110-660). The DTT-reduced protein migrates as a 75-80 kDa polypeptide on SDS-PAGE because of glycosylation. This protein is produced in human cells, without the use of serum. The human cells expression system allows human like glycosylation and folding, and often supports higher specific activity of the protein. This recombinant protein is expressed without artificial tags.
