Rat alpha 1­Microglobulin (alpha1­m/A1M; also protein HC) is a secreted 25­26kD glycoprotein member of the lipocalin family, calycin superfamily of molecules. It is expressed by hepatocytes, keratinocytes, and endodermal derivatives in the embryo. Alpha 1­Microglobulin 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 1­Microglobulin circulates either as a monomer, or bound to IgA, albumin or prothrombin. Rat alpha 1­Microglobulin is generated through cleavage of a precursor molecule termed AMBP. This AMBP should not be confused with AMBP­1, a 120­140kD adrenomedullin­binding protein that is also known as Complement Factor H. The AMBP precursor contains a 19 aa signal sequence, an N­terminal 183aa alpha 1­Microglobulin protein (aa20­202), and a C­terminal serine protease inhibitor termed bikunin (aa205­349). Alpha 1­Microglobulin possesses one lipocalin domain (aa41­186). Although cleavage of AMBP in the Golgi apparatus typically generates a 25kD alpha 1­Microglobulin and 28kD bikunin molecule, the 55­65kD AMBP precursor can also be released intact. In human, alpha 1­Microglobulin will undergo extracellular processing, generating an isoform that is missing the C­terminal four amino acids. There are four potential isoform variants. One utilizes an alternative start site at Met181, a second contains an Asn substitution for aa 112­228, a third possesses an 11aa substitution for aa1­141, and a fourth shows a 17aa substitution for aa201­349. Over aa20­202, rat alpha 1­Microglobulin shares 76% and 86% aa sequence identity with human and mouse alpha 1­Microglobulin, respectively.
