Target

  • Function

    Cytokine that binds to TNFRSF13B/TACI and TNFRSF17/BCMA. TNFSF13/APRIL binds to the same 2 receptors. Together, they form a 2 ligands -2 receptors pathway involved in the stimulation of B-and T-cell function and the regulation of humoral immunity. A third B-cell specific BAFF-receptor (BAFFR/BR3) promotes the survival of mature B-cells and the B-cell response.
  • Tissue specificity

    Abundantly expressed in peripheral blood Leukocytes and is specifically expressed in monocytes and macrophages. Also found in the spleen, lymph node, bone marrow, T-cells and dendritic cells. A lower expression seen in placenta, heart, lung, fetal liver, thymus, and pancreas.
  • Sequence similarities

    Belongs to the tumor necrosis factor family.
  • Post-translational
    modifications

    The soluble form derives from the membrane form by proteolytic processing.
    N-glycosylated.
  • Cellular localization

    Secreted and Cell membrane.
  • Target information above from: UniProt accession Q9Y275 The UniProt Consortium
    The Universal Protein Resource (UniProt) in 2010
    Nucleic Acids Res. 38:D142-D148 (2010) .
