Application

Inhibits all classes of endoproteases by forming a complex with the protease. When the protease cleaves the macroglobulin "bait" sequence, the macroglobulin rearranges and traps the protease.

Biochem/physiol Actions

α2-Macroglobulin is found abundantly in plasma and interstitial fluids. The protease-α2-M balance plays an important role in mediating inflammatory tissue destruction. Serum levels of α2-M and protease-α2-M complexes are increased in patients with sepsis, emphysema, periodontitis, rheumatoid arthritis, and other inflammatory diseases, and oxidant inactivation of α2-M may contribute to tissue destruction during inflammation.

alpha 2-Macroglobulin (alpha 2M) is a large plasma glycoprotein that has long been known as an irreversible inhibitor of a variety of proteinases. More recently, it has been reported that numerous growth factors, cytokines and hormones bind to alpha 2M

Treatment of the human plasma proteinase inhibitor alpha 2-macroglobulin (alpha 2M) with proteinase results in conformational changes in the inhibitor and subsequent activation and cleavage of the internal thiolester bonds of alpha 2M. Previous studies from this laboratory have shown
