CD21 also known as complement receptor 2 (CR2) has an approximate mass of 145 kDa. CD35 also called complement receptor 1 (CR1) varies in mass between 190 to 280 kDa due to glycosylation. These proteins are expressed on the surface of B cells dendritic cells and some epithelial cells. Both markers participate in the immune system aiding in the clearance of pathogens and foreign antigens.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nCD21 and CD35 mediate the binding and clearance of opsonized antigens. These proteins form part of larger complexes where they act as receptors for complement proteins like C3d and C4b. CD21 enhances B cell activation by bridging the B-cell receptor with C3d-bound antigens. Meanwhile CD35 helps clear immune complexes reducing inflammation and facilitating healing.\u003cbr\u003e\nPathways\u003cbr\u003e\nCD21\/CD35 plays a significant role in the complement cascade and immune complex clearance pathways. Both CD21 and CD35 connect to other complement proteins such as C3. CD21 also interacts with proteins like CD19 and CD81 forming part of the B-cell co-receptor complex which amplifies B-cell receptor signaling and assists in immune response regulation.\u003cbr\u003e\nCD21\/CD35 involvement links with autoimmune conditions such as systemic lupus erythematosus and chronic lymphocytic leukemia. In these diseases defective or altered CD21\/CD35 expression can lead to inadequate immune complex clearance or abnormal B cell activation. Dysfunction in this system may alter interactions with proteins like CD19 contributing to disease progression.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46855396950185,"sku":"ab155579","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/abcam-ab155579","provider":"Iright","version":"1.0","type":"link"}
