Target

  • Function
    This protein recognizes C4b and C3b fragments that condense with cell-surface hydroxyl or amino groups when nascent C4b and C3b are locally generated during C4 and c3 activation. Interaction of daf with cell-associated C4b and C3b polypeptides interferes with their ability to catalyze the conversion of C2 and factor B to enzymatically active C2a and Bb and thereby prevents the formation of C4b2a and C3bBb, the amplification convertases of the complement cascade.
  • Tissue specificity
    Expressed on the plasma membranes of all cell types that are in intimate contact with plasma complement proteins. It is also found on the surfaces of epithelial cells lining extracellular compartments, and variants of the molecule are present in body fluids and in extracellular matrix.
  • Sequence similarities
    Belongs to the receptors of complement activation (RCA) family.
    Contains 4 Sushi (CCP/SCR) domains.
  • Domain
    The first Sushi domain (SCR1) is not necessary for function. SCR2 and SCR4 provide the proper conformation for the active site on SCR3.
  • Post-translational
    modifications
    The Ser/Thr-rich domain is heavily O-glycosylated.
  • Cellular localization
    Cell membrane.

Images

  • Overlay histogram showing THP1 cells stained with ab28112 (red line). The cells were fixed with 80% methanol (5 min) and incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab28112, 10µl/1x106 cells) for 30 min at 22°C. Isotype control antibody (black line) was mouse IgM (FITC) (ab91546, 10µl/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive signal in THP1 cells fixed with 4% paraformaldehyde (10 min) used under the same conditions.
    Please note that Abcam do not have any data for use of this antibody on non-fixed cells. We welcome any customer feedback.
