CD21 is a single-pass type 2 transmembrane protein that serves as the complement receptor for C3d and the Epstein-Barr virus. CD21 labels follicular dendritic cells and mature B cells particularly in marginal and mantle zone of lymphoid tissues. It is a useful marker to identify neoplasms derived from follicular dendritic cells.
