Target

  • Function
    Involved in the costimulatory signal, essential for T-cell proliferation and production of IL10 and IFNG, in an IL2-dependent and a PDCD1-independent manner. Interaction with PDCD1 inhibits T-cell proliferation and cytokine production.
  • Tissue specificity
    Highly expressed in the heart, skeletal muscle, placenta and lung. Weakly expressed in the thymus, spleen, kidney and liver. Expressed on activated T- and B-cells, dendritic cells, keratinocytes and monocytes.
  • Sequence similarities
    Belongs to the immunoglobulin superfamily. BTN/MOG family.
    Contains 1 Ig-like C2-type (immunoglobulin-like) domain.
    Contains 1 Ig-like V-type (immunoglobulin-like) domain.
  • Cellular localization
    Cell membrane and Endomembrane system.

  • Immunocytochemistry/ Immunofluorescence analysis of CHO-PD-L1 (PD-L1 stably expessed Chinese hamster ovary epithelial cell) cells labeling PD-L1 with purified ab228462 at 1/50 (2 µg/ml). Cells were fixed in 4% paraformaldehyde and permeabilized with 0.1% Triton X-100. Cells were counterstained with ab195889 Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker (Alexa Fluor® 594) 1/200 (2.5 µg/ml). Goat anti rabbit IgG (Alexa Fluor® 488, ab150077) was used as the secondary antibody at 1/1000 (2 µg/ml) dilution. DAPI was used as nuclear counterstain. PBS instead of the primary antibody was used as the secondary antibody only control.
