Haptoglobin

abbr. Hp (approved gene symbol: HP). A tetrameric plasma glycoprotein produced primarily by hepatocytes. Haptoglobulin is polymorphic due to the existence of two allelic forms of the alpha chains (HP1; HP-alpha-1 [haptoglobin-alpha-1], also: HP-alpha 1-1 [haptoglobin-alpha 1-1]), 9 kDa, 83 amino acids; and HP2; HP-alpha-2 [haptoglobin-alpha-2], also: HP-alpha 2-2 [haptoglobin-alpha 2-2]) 17.3 kDa, 142 amino acids). Haptoglobin is produced as a proprotein, termed Prohaptoglobin ... ... ... ...
