CD163, also known as hemoglobin scavenger receptor, is a type I transmembrane protein expressed exclusively in monocytes and macrophages. It is a scavenger receptor cysteine-rich superfamily (SRCR-SF) protein that contains nine SRCR motifs in its extracellular region. Two alternatively spliced cytoplasmic variants of human CD163 exist. A soluble form of CD163 can also be released by metalloproteinase-mediated shedding of the extracellular domain. CD163 mediates the endocytosis of haptoglobin-hemoglobin complexes.
