NCIt definition : Tumor necrosis factor receptor superfamily member 6 (335 aa, 38 kDa) is encoded by
the human FAS gene. This protein is involved in the regulation of apoptosis.;
NCIt note : FAS differentiation antigen is expressed in the thymus, liver, ovary, and heart, and
on a variety of cell lines including myeloid and lymphoblastoid cell lines. Its primary
role is to regulate T-cell development in the thymus and to regulate peripheral immune
responses, by triggering apoptosis. FAS is a member of the TNFR/NGFR superfamily.
Activation of FAS by FAS ligand results in the formation of a death-inducing signaling
complex with the signal adaptor protein FADD and with procaspase 8. This association
generates CASP8, activating a cascade of caspases. (OMIM);
