  • Function

    Cytokine that binds to TNFRSF9. Induces the proliferation of activated peripheral blood T-cells. May have a role in activation-induced cell death (AICD). May play a role in cognate interactions between T-cells and B-cells/macrophages.
  • Tissue specificity

    Expressed in brain, placenta, lung, skeletal muscle and kidney.
  • Sequence similarities

    Belongs to the tumor necrosis factor family.
