The molecular size is 130 kDa. The receptor belongs to the scavenger receptor cysteine rich family type B and consists of a 1048 amino acid residues extracellular domain, a single transmembrane segment and a cytoplasmic tail with several splice variants.
Differences between mice and humans in CD163 biology are important to note since preclinical studies are frequently conducted in mice. sCD163 shedding occurs in humans but not mice, due to the emergence of an Arg-Ser-Ser-Arg sequence in humans, essential for enzymatic cleavage by ADAM17.[13] Human CD163, but mouse CD163, exhibits a strikingly higher affinity to hemoglobin-haptoglobin complex compared to hemoglobin alone.[14]
