Hemopexin (or haemopexin; Hpx; Hx), also known as beta-1B-glycoprotein, is a glycoprotein that in humans is encoded by the HPX gene and belongs to the hemopexin family of proteins. Hemopexin is the plasma protein with the highest binding affinity for heme. Hemoglobin itself circulating alone … Visualizza altro Takahashi et al. (1985) determined that human plasma hemopexin consists of a single polypeptide chain of 439 amino acids residues with six intrachain disulfide bridges and has a molecular mass of approximately … Visualizza altro Cai and Law (1986) prepared a cDNA clone for hemopexin, by Southern blot analysis of human/hamster hybrids containing different combinations of human chromosomes, assigned the HPX gene to human chromosome 11.
