  • 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

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

    Secreted and Cell membrane.
  • Information by UniProt


  • SDS-PAGE analysis: Lane 1: MWt Marker, Lane 2: 1 μg ab157285, stained with Imperial stain
  • ab157285 mediates survival of freshly isolated splenocytes.

    Method: On day 0 splenocytes were isolated from a freshly collected C57Bl6 spleen. An aliquot of the splenocytes was analyzed on FACS and gated on the SSC-FSC panel. FACS settings were saved. The rest of the cells was put in culture with media alone or with increasing concentrations of ab157285 as indicated. After three days in culture, cells were harvested and analyzed on FACS with the saved setting. Splenocytes Survival Index (ratio % living/% dead cells) was calculated and plotted.
