Background

Human alpha 1-Microglobulin (alpha1-m/A1M; also protein HC) is a secreted, 31-32 kDa glycoprotein member of the lipocalin family, calycin superfamily of molecules. It is expressed by hepatocytes, keratinocytes, and endodermal derivatives in the embryo.  alpha 1-Microglobulin appears to act as a heme scavenger, protecting cells and collagen against oxidative damage. It also acts as an immunosuppressant, inhibiting polyclonal lymphocyte activation and dampening granulocyte migration in response to chemokines. alpha 1-Microglobulin circulates either as a monomer, or bound to IgA, albumin or prothrombin. Human alpha 1-Microglobulin is generated through cleavage of a precursor molecule termed AMBP. This AMBP should not be confused with AMBP-1, a 120-140 kDa adrenomedullin-binding protein that is also known as Complement Factor H. The AMBP precursor contains a 19 aa signal sequence, an N-terminal 183 aa alpha 1-Microglobulin protein (aa 20-203), and a C-terminal serine protease inhibitor termed bikunin (aa 206-352). alpha 1-Microglobulin possesses one lipocalin domain (aa 42-186). Although cleavage of AMBP in the Golgi apparatus typically generates a 31 kDa alpha 1-Microglobulin and 28 kDa bikunin molecule, the 60-65 kDa AMBP precursor can also be released intact.  alpha 1-Microglobulin will undergo extracellular processing, generating a 30 kDa isoform that is missing aa 199-203. There is one splice variant that shows a deletion of aa 48-57.  Over aa 20-203, human alpha 1-Microglobulin shares 76% aa sequence identity with both mouse and rat alpha 1-Microglobulin.
