Hemopexin Products
Hemopexin (HPX) is a 60 kDa plasma glycoprotein with two four-bladed beta-propeller folds. This structural motif has been found in other proteins including collagenases and provides sites for protein-protein interactions. The liver is the major synthesizing organ. Expression in the central nervous system, in the retina, and in peripheral nerves has also been observed. Hemopexin belongs to the family of the acute-phase proteins whose synthesis is induced after an inflammatory event. Hemopexin participates in maintaining and recycling the iron pool by utilizing its high binding affinity toward heme composed of protoporphyrin X and iron. It also functions in preventing oxidation caused by heme after hemolysis. Hydrophobic heme molecules can intercalate into lipid membranes and participate in the oxidation of lipid membrane components through the Fenton reaction resulting in lipid peroxidation. Hemopexin undergoes a conformational change upon the binding of heme. The conformational change allows hemopexin to interact with a specific receptor, forming a complex which is then internalized. In the plasma, it is likely that heme binds albumin (35 - 55 g/L) first because of the higher concentration of albumin in plasma than hemopexin (0.5 - 1.2 g/L), and is then transferred to hemopexin, which has a much higher affinity (Kd ~ 1 pM) toward heme. Heme concentrations in plasma increase after hemolysis, which is associated with several pathological conditions such as reperfusion injury and ischemia.
