|Function||As a result of hemolysis, hemoglobin is found to accumulate in the kidney and is secreted in the urine. Haptoglobin captures, and combines with free plasma hemoglobin to allow hepatic recycling of heme iron and to prevent kidney damage. Haptoglobin also acts as an Antimicrobial; Antioxidant, has antibacterial activity and plays a role in modulating many aspects of the acute phase response. Hemoglobin/haptoglobin complexes are rapidely cleared by the macrophage CD163 scavenger receptor expressed on the surface of liver Kupfer cells through an endocytic lysosomal degradation pathway.|
|Tissue Location||Expressed by the liver and secreted in plasma.|

This gene encodes a preproprotein, which is processed toyield both alpha and beta chains, which subsequently combine as atetramer to produce haptoglobin. Haptoglobin functions to bind freeplasma hemoglobin, which allows degradative enzymes to gain accessto the hemoglobin, while at the same time preventing loss of ironthrough the kidneys and protecting the kidneys from damage byhemoglobin. Mutations in this gene and/or its regulatory regionscause ahaptoglobinemia or hypohaptoglobinemia. This gene has alsobeen linked to diabetic nephropathy, the incidence of coronaryartery disease in type 1 diabetes, Crohn's disease, inflammatorydisease behavior, primary sclerosing cholangitis, susceptibility toidiopathic Parkinson's disease, and a reduced incidence ofPlasmodium falciparum malaria. A similar duplicated gene is locatednext to this gene on chromosome 16. Multiple transcript variantsencoding different isoforms have been found for this gene.
