Tumor necrosis factor receptor superfamily member 6 (TNFRSF6), also known as fas cell surface death receptor (Fas) TNFRSF6 (also known as fas cell surface death receptor (FasR) or Fas, APT1, CD95, FAS1, APO-1, FASTM, ALPS1A) contains a death domain and plays a central role in the physiological regulation of programmed cell death. It has been implicated in the pathogenesis of various malignancies and diseases of the immune system. The receptor interactions with the Fas ligand (FasL), allowing the formation of a death-inducing signaling complex that includes Fas-associated death domain protein (FADD), caspase 8, and caspase 10; autoproteolytic processing of the caspases in the complex triggers a downstream caspase cascade, leading to apoptosis. This receptor has also been shown to activate NF-kappaB, MAPK3/ERK1, and MAPK8/JNK, and is involved in transducing the proliferating signals in normal diploid fibroblast and T cells. Of the several alternatively spliced transcript variants, some are candidates for nonsense-mediated mRNA decay (NMD). Isoforms lacking the transmembrane domain may negatively regulate the apoptosis mediated by the full length isoform. |
