UniProt Comment
  • 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.

All locus annotations are based on the sentinel SNP (rs8044476) and 4 proxy variant(s) that is/are in linkage disequilibrium r2 ≥ 0.8. Linkage disequilibrium is based on data from the 1000 Genomes Project, phase 3 version 5, European population and was retrieved using SNiPA's Block Annotation feature.
