Recombinant human CD137-Fc

Specificity

NB100-64306 recognizes human CD137, an 83kD type I integral membrane protein, otherwise known as 4-1BB. The CD137 molecule is primarily expressed on activated T-cells. It is a costimulatory member of the tumour necrosis receptor family and is reported to regulate T-cell activation and proliferation.

Background: 4-1BB/TNFRSF9/CD137

4-1BB, also called CD137 and tumor necrosis factor receptor superfamily member 9 (TNFRSF9), is a type I surface glycoprotein expressed on activated T cell and natural killer (NK) cells (1,2). Human 4-1BB protein is 255 amino acids (aa) in length with a theoretical molecular weight of 28 kDa. It contains an extracellular domain, a helical transmembrane domain, and a cytoplasmic/intracellular domain (3). 4-1BB/TNFRSF9/CD137 is a costimulatory receptor that binds the ligand 4-1BBL/CD137L which is primarily expressed on antigen presenting cells (APCs) such as dendritic cells (DCs), macrophages, and B cells (1,2,4,5). The 4-1BB receptor-ligand interaction results in recruitment of TNFR-associated factor (TRAF) family adaptor proteins to 4-1BB's cytoplasmic domain (1,2,4,5). TRAF1, TRAF2, and TRAF3 are found in various homodimer and/or heterodimer configurations. Their recruitment to 4-1BB/CD137 initiates signalosome formation as well as activation of the nuclear factor-kappa B (NF-kappaB) and mitogen-activated protein kinase (MAPK) signaling cascade (1,4,5). 4-1BB/TNFRSF9/CD137 stimulation leads to increased cellular cytotoxic activity and pro-inflammatory cytokine production (1,2,4). Given its role in immune cell activation, 4-1BB has become a promising target for cancer immunotherapy (1,2,4). Current approaches to target 4-1BB include agonistic monoclonal and bispecific anti-4-1BB antibodies and well as utilizing the cytoplasmic domain of 4-1BB in generating chimeric antigen receptors (CARs) (1,2,4). 4-1BB agonists in clinical trials include Urelumab and Utolimumab. Utolimumab also has ligand blocking properties whereas Urelumab does not (1,2,4). Anti-4-1BB monoclonal antibodies are being tested as monotherapy as well as combination therapy with either other immunostimulatory monoclonal antibodies or with checkpoint blockade antibodies like anti-PD-1 (1,2,4).
