| Introduction | Complement receptor 1 (CR1) also known as CD35, cluster of differentiation 35, is a protein that in humans is encoded by the CR1 gene. CR1 can act as a negative regulator of the complement cascade, mediate immune adherence and phagocytosis and inhibit both the classic and alternative pathways. Complement receptor 2 (CR2), also known as CD21, cluster of differentiation 21, is a protein that in humans is encoded by the CR2 gene. CR2 is involved in the complement system. It binds to iC3b (inactive derivative of C3b), C3dg, or C3d. B cells have CR2 receptors on their surfaces, allowing the complement system to play a role in B-cell activation and maturation. |
