Notes: α1-Microglobulin (A1M) is a glycoprotein and member of the lipocalin protein family encoded by the α1-microglobulin-bikunin precursor gene AMBP.{69260,69261} It is expressed in all tissues, except the CNS, and in blood.{69261} A1M is synthesized in the liver, secreted into circulation where it forms complexes with IgA, albumin, and prothrombin, and subsequently equilibrated over the vessel wall between the intra- and extravascular compartments of all organs.{69260,69262} A1M is heterogenous in charge and size, covalently bound to chromophores, and exists in various glycoforms.{69262} It binds free radicals, as well as heme, and has roles in various diseases involving oxidative stress. Plasma levels of A1M are increased and positively correlated with plasma peroxidation and the level of protein carbonyls in patients with preeclampsia.{69262,69263} Urinary levels of A1M are positively correlated with increased risk of acute kidney injury and other adverse events following cardiac surgery in adult patients.{69264} Cayman's α1-Microglobulin (human, recombinant) protein consists of 195 amino acids, has a calculated molecular weight of 22.3 kDa, and a predicted N-terminus of Gly20 after signal peptide cleavage. By SDS-PAGE, under reducing conditions, the apparent molecular mass of the protein is 32.8 kDa due to glycosylation.
