    • Function

      May participate in the regulation of T-cell-mediated immune response. May play a protective role in tumor cells by inhibiting natural-killer mediated cell lysis as well as a role of marker for detection of neuroblastoma cells. May be involved in the development of acute and chronic transplant rejection and in the regulation of lymphocytic activity at mucosal surfaces. Could also play a key role in providing the placenta and fetus with a suitable immunological environment throughout pregnancy. Both isoform 1 and isoform 2 appear to be redundant in their ability to modulate CD4 T-cell responses. Isoform 2 is shown to enhance the induction of cytotoxic T-cells and selectively stimulates interferon gamma production in the presence of T-cell receptor signaling.
    • Tissue specificity

      Ubiquitous but not detectable in peripheral blood lymphocytes or granulocytes. Weakly expressed in resting monocytes. Expressed in dendritic cells derived from monocytes. Expressed in epithelial cells of sinonasal tissue. Expressed in extravillous trophoblast cells and Hofbauer cells of the first trimester placenta and term placenta.
    • Sequence similarities

      Belongs to the immunoglobulin superfamily. BTN/MOG family.
      Contains 2 Ig-like C2-type (immunoglobulin-like) domains.
      Contains 2 Ig-like V-type (immunoglobulin-like) domains.

    • Formalin-fixed, paraffin-embedded human prostate carcinoma tissue stained for CD276 using ab226256 at 1/5000 dilution in immunohistochemical analysis.

      Detection: DAB staining. Counterstain: Hematoxylin.

    • CD276 was immunoprecipitated from HeLa (human epithelial cell line from cervix adenocarcinoma) whole cell lysate (prepared using NETN buffer; 1 mg for IP, 20% of IP loaded) with ab226256 at 6 µg/mg lysate. Western blot was performed from the immunoprecipitate using a different rabbit anti-CD276 antibody at 1 µg/ml.

      Lane 1: ab226256 IP in HeLa whole cell lysate.

      Lane 2: Control IgG IP in HeLa whole cell lysate.

      Detection: Chemiluminescence with exposure time of 3 minutes.

    • MCF7 (human breast adenocarcinoma cell line) (left panel) and CD276 transfected HEK-293 (human epithelial cell line from embryonic kidney) (right panel) cells stained for CD276 using ab226256 at 1/5000 dilution in immunohistochemical analysis.

      Detection: DAB staining.
