靶标

  • 功能Is able to inhibit all four classes of proteinases by a unique 'trapping' mechanism. This protein has a peptide stretch, called the 'bait region' which contains specific cleavage sites for different proteinases. When a proteinase cleaves the bait region, a conformational change is induced in the protein which traps the proteinase. The entrapped enzyme remains active against low molecular weight substrates (activity against high molecular weight substrates is greatly reduced). Following cleavage in the bait region a thioester bond is hydrolyzed and mediates the covalent binding of the protein to the proteinase.
  • 组织特异性Secreted in plasma.
  • 序列相似性Belongs to the protease inhibitor I39 (alpha-2-macroglobulin) family.
  • 发展阶段Contrary to the rat protein, which is an acute phase protein, this protein is always present at high levels in circulation.
  • 细胞定位Secreted.

    Predicted band size : 163 kDa
    Observed band size : ~178 kDa (why is the actual band size different from the predicted?)
    Additional bands at : >200 kDa (possible non-specific binding).
    Alpha-2-Macroglobulin is a 720 kDa homotetrameric glycoprotein composed of four identical 180kDa subunits. The predicted band size of 163 kDa is the MW of the unprocessed precursor.

Thank you for your reply.

Indeed we do not have another mouseanti alpha 2 Macroglobulin antibody which would be tested in Western blot already. We have the ab116593, which however has only been tested in ELISA, IP and RIA.

There is ...
