Target

  • Function

    Receptor for complement C3Dd, for the Epstein-Barr virus on human B-cells and T-cells and for HNRPU. Participates in B lymphocytes activation.
  • Tissue specificity

    Mature B-lymphocytes, T-lymphocytes, pharyngeal epithelial cells, astrocytes and follicular dendritic cells of the spleen.
  • Involvement in disease

    Genetic variations in CR2 are associated with susceptibility to systemic lupus erythematosus type 9 (SLEB9) [MIM:610927]. Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with a complex genetic basis. SLE is an inflammatory, and often febrile multisystemic disorder of connective tissue characterized principally by involvement of the skin, joints, kidneys, and serosal membranes. It is thought to represent a failure of the regulatory mechanisms of the autoimmune system.
  • Sequence similarities

    Belongs to the receptors of complement activation (RCA) family.
    Contains 15 Sushi (CCP/SCR) domains.
  • Cellular localization

    Membrane.

Images

  • ab75985 staining CD21 in Cynomolgus Monkey whole blood by Flow Cytometry. Red blood cells were lysed in PBS + 1% BSA and 0.01% sodium azide, fixed in paraformaldehyde and incubated with the primary antibody (1/100 in PBS + 1% BSA and 0.01% sodium azide) for 1 hour at 4°C. An Alexa Fluor® 488-conjugated Goat anti-rabbit IgG polyclonal (1/100) was used as the secondary antibody.
    Gating Strategy: Live Lymphocytes.

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab75985).

  • ab75985 staining CD21 antibody in Raji (human Burkitt's lymphoma) cells by ICC/IF (Immunocytochemistry/immunofluorescence). Cells were fixed with 100% methanol. Samples were incubated with primary antibody at a dilution of 1/500. A goat anti rabbit IgG (Alexa Fluor® 488) (ab150077) was used as the secondary antibody at a dilution of 1/1000.

    DAPI was used as a nuclear counterstain and the negative control was PBS only.
