Description

4-1BBL (4-1BB ligand), also known as CD137L or TNFSF9, is single pass type II transmembrane protein that belongs to the TNF superfamily (TNFSF).  4-1BBL is a  a bidirectional signal transducer that acts as a high affinity ligand for 4-1BB/CD137/TNFRSF9, a member of the TNF-receptor superfamily (TNFRSF).  Members of the TNFRSF have been shown to play critical roles in regulating cellular activation, differentiation and apoptosis.  The extracellular domain (ECD) of 4-1BBL has a jellyroll, β-sandwich tertiary structure that is similar to other TNFSF members. 4-1BBL is expressed by activated B cells, macrophages, dendritic cells, activated T cells, neurons and astrocytes.  A soluble active form of 4-1BBL is detected in humans, presumably generated by MMP activity. 4-1BBL may signal through both 4-1BB and itself as its cytoplasmic tail participates in reverse signaling to induce apoptosis in T cells and secretion of cytokines such as IL6 and TNFα by monocytes. 4-1BBL/4-1BB signaling is involved in the antigen presentation process and in the generation of cytotoxic T cells.  4-1BBL/4-1BB interaction also provides a co-stimulatory signal to T cells, and increases T cell proliferation and cytokines production. 4-1BBL may play a key role in T cell recall response and maintaining T cell numbers. 4-1BBL is required for the optimal CD8 responses in CD8 T cells. 4-1BBL is expressed on cancer cells, and is thought to be involved in T cell-tumor cell interaction.  4-1BBL may also play a role in interactions between T-cells and B-cells/macrophages.  4-1BBL is implicated in cancers, infectious diseases and autoimmune diseases.
