CD68, an 110kD Type I integral membrane glycoprotein, is a member of Lysosome-associated membrane protein (LAMP) family. It belongs to the family of hematopoietic mucin-like molecules and is predominantly expressed on monocytes and tissue macrophages, dendritic cells, granulocytes, activated T-cells and subset of B-cells. Its heavily glycosylated extracellular domain consists of a mucin domain separated from the LAMP domain by a proline-rich spacer region. It physiological function has been elusive but reports suggest its role in binding and uptake of oxidized LDLs accumulated in macrophage-derived foam cells within atherosclerotic plaques.
