Recombinant Human TNFRSF9 protein, Fc-tagged

Cat.No.: TNFRSF9-232H
Product Overview: Recombinant Human TNFRSF9(Leu24-Gln186) fused with Fc region of Human IgG1 at C-terminal was expressed in HEK293.
Description: 4-1BB, also known as CD137 and TNFRSF9, is an approximately 30 kDa transmembrane glycoprotein in the TNF receptor superfamily. 4-1BB functions in the development and activation of multiple immune cells. Mature human 4-1BB consists of a 163 amino acid (aa) extracellular domain (ECD) with four TNFR cysteine‑rich repeats, a 27 aa transmembrane segment, and a 42 aa cytoplasmic domain. Within the ECD, cynomolgus 4-1BB shares 95%, 57%, and 57% aa sequence identity with human, mouse, and rat 4-1BB, respectively. 4-1BB is expressed as a disulfide-linked homodimer on various populations of activated T cell including CD4+, CD8+, memory CD8+, NKT, and regulatory T cells as well as on myeloid and mast cell progenitors, dendritic cells, mast cells, and bacterially infected osteoblasts. It binds with high affinity to the transmembrane 4-1BB Ligand/TNFSF9 which is expressed on antigen presenting cells and myeloid progenitor cells. This interaction co-stimulates the proliferation, activation, and/or survival of the 4-1BB expressing cell. It can also enhance the activation-induced cell death of repetitively stimulated T cells. Mice lacking 4-1BB show augmented T cell activation, perhaps due to its absence on regulatory T cells.
4-1BB can associate with OX40 on activated T cells, forming a complex that responds to either ligand and inhibits Treg and CD8+ T cell proliferation. Reverse signaling through 4-1BB Ligand inhibits the development of dendritic cells, B cells, and osteoclasts but supports mature dendritic cell survival and co‑stimulates the proliferation and activation of mast cells. 4-1BB activation enhances CD8+ T cell and NK cell mediated anti-tumor immunity. It also contributes to the development of inflammation in high fat diet-induced metabolic syndrome. Soluble forms of 4-1BB and 4-1BB Ligand circulate at elevated levels in the serum of rheumatoid arthritis and hematologic cancer patients, respectively.
