Death receptor 6 (DR6), also known as tumor necrosis factor receptor superfamily member 21 (TNFRSF21), is a cell surface receptor of the tumor necrosis factor receptor superfamily which activates the JNK and NF-κB pathways.[5][6] It is mostly expressed in the thymus, spleen and white blood cells.[7] The Gene for DR6 is 78,450 bases long and is found on the 6th chromosome. This is transcribed into a 655 amino acid chain weighing 71.8 kDa. Post transcriptional modifications of this protein include glycosylation on the asparagines at the 82, 141, 252, 257, 278, and 289 amino acid locations.[8]
