==Overview==
Complement receptor 2 (CR2/CD21) is an important receptor that amplifies B, lymphocyte activation by bridging the innate and adaptive immune systems., CR2 ligands include complement C3d and Epstein-Barr virus glycoprotein, 350/220. We describe the x-ray structure of this CR2 domain in complex, with C3d at 2.0 angstroms. The structure reveals extensive main chain, interactions between C3d and only one short consensus repeat (SCR) of CR2, and substantial SCR side-side packing. These results provide a detailed, understanding of receptor-ligand interactions in this protein family and, reveal potential target sites for molecular drug design.
