Human Tumor Necrosis Factor Receptor Superfamily, Member 21 (TNFRSF21) Protein

Background

TNF receptor superfamily member 21 (TNFRSF21), also known as death receptor 6 (DR6), is a member of the tumor necrosis factor receptor (TNFR) superfamily. Like other TNFR members, TNFRSF21 is involved in processes that modulate immune responses, cell death, and survival pathways. This receptor is particularly involved in apoptosis, immune cell regulation, and central nervous system functions. TNFRSF21/DR6 is expressed in a range of tissues but is predominantly found in lymphoid organs, nervous system cells, and tissues associated with inflammatory processes. TNFRSF21 plays a significant role in neuroinflammation and neurodegeneration, as well as in the regulation of immune responses. It is a type I transmembrane protein that acts as a receptor for ligands like tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) and amyloid precursor protein (APP)-derived peptides. Due to its involvement in cell apoptosis, particularly in neural cells, TNFRSF21 has garnered interest for its potential therapeutic applications in neurodegenerative diseases such as Alzheimer’s disease. Additionally, its function in immune cell regulation places it as a candidate target in autoimmune diseases and certain cancers.
