Complement component (3d/Epstein Barr virus) receptor 2, also known as CR2 and CD21, is a protein involved in the complement system. It binds to C3d. B cells have CR2 receptors on their surfaces, allowing the complement system to play a role in B-cell activation and maturation [1]

Complement component receptor-2 (CR2) is the membrane protein on B lymphocytes to which the Epstein-Barr virus (EBV) binds during infection of these cells. See also MIM 120620. Yefenof et al. (1976) found complete overlapping of EBV receptors and C3 (MIM 120700) receptors on human B lymphocytes.[supplied by OMIM][1]
