Description
The protein encoded by this gene is a member of the TNF-receptor superfamily. This receptor contributes to the clonal expansion, survival, and development of T cells. It can also induce proliferation in peripheral monocytes, enhance T cell apoptosis induced by TCR/CD3 triggered activation, and regulate CD28 co-stimulation to promote Th1 cell responses. The expression of this receptor is induced by lymphocyte activation. TRAF adaptor proteins have been shown to bind to this receptor and transduce the signals leading to activation of NF-kappaB.
Bio-activity
Measured by its binding ability in a functional ELISA. When Recombinant Human 4-1BB/TNFRSF9/CD137 is immobilized at 50 ng/mL, 100 μL/well, the concentration of Recombinant Human 4-1BB Ligand/TNFSF9 that produces 50% of the optimal binding response is approximately 2.5-12.5 ng/mL.
Storage
