Produced in HEK 293 cells. The extracellular domain of human TRAIL-R1 (aa 1 - 238) is fused to the Fc portion of human IgG1.


DR4 is a transmembrane protein, also called TRAIL receptor 1 (TRAIL-R1). The ligand for this DR4 death receptor has been identified and termed TRAIL, which is a member of the TNF family. DR4, as many other receptors (Fas, TNFR1, etc.), mediates apoptosis and NF kappaB activation in many cells and tissues.
Apoptosis, a programmed cell death, is a operating process in normal cellular differentiation and development of multicellular organisms. Apoptosis is induced by coupled of certain cytokines (TNF family - TNF, Fas ligand) and their death domain containing receptors (TNFR1, Fas receptor).
