ORM2 Protein Description

ORM2 is a member of the calycin superfamily, lipocalin family. Lipocalins are characterized by  limited regions of sequence homology and a common tertiary structure architecture. They are associated with many biological processes and can be found in gram negative bacteria, vertebrate cells, and invertebrate cells, and in plants. Lipocalins transport small hydrophobic molecules such as steroids, bilins, retinoids, and lipids. ORM2 functions as transport protein in the blood stream. It is expressed by the liver and secreted in plasma. It appears to function in modulating the activity of the immune system during the acute-phase reaction. It binds various hydrophobic ligands in the interior of its beta-barrel domain. It also binds synthetic drugs and influences their distribution and availability.
