Target

  • Function

    Receptor for TNFSF5/CD40LG.
  • Tissue specificity

    B-cells and in primary carcinomas.
  • Involvement in disease

    Defects in CD40 are the cause of hyper-IgM immunodeficiency syndrome type 3 (HIGM3) [MIM:606843]; also known as hyper-IgM syndrome 3. HIGM3 is an autosomal recessive disorder which includes an inability of B cells to undergo isotype switching, one of the final differentiation steps in the humoral immune system, an inability to mount an antibody-specific immune response, and a lack of germinal center formation.
  • Sequence similarities

    Contains 4 TNFR-Cys repeats.
  • Cellular localization

    Secreted and Cell membrane.
  • Target information above from: UniProt accession P25942 The UniProt Consortium
    The Universal Protein Resource (UniProt) in 2010

      ab224639 staining CD40 in wild-type U2OS cells (top panel) and CD40 knockout U2OS cells (bottom panel). The cells were fixed with PFA (10min), permeabilized with 0.1% Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated with ab224639 at 1/100 dilution and ab7291 (Tubulin) at 1/1000 dilution overnight at +4°C, followed by a further incubation at room temperature for 1h with a goat secondary antibody to rabbit IgG (Alexa Fluor® 488) (ab150081) at 2 μg/ml (shown in green) and a goat secondary antibody to mouse IgG (Alexa Fluor® 594) (ab150120) at 2 μg/ml (shown in pseudo color red).  Nuclear DNA was labelled in blue with DAPI.

      Image was taken with a confocal microscope (Leica-Microsystems, TCS SP8).
