Function

Receptor for TNFSF6/FASLG. The adapter molecule FADD recruits caspase-8 to the activated receptor. The resulting death- inducing signaling complex (DISC) performs caspase-8 proteolytic activation which initiates the subsequent cascade of caspases (aspartate-specific cysteine proteases) mediating apoptosis. FAS- mediated apoptosis may have a role in the induction of peripheral tolerance, in the antigen-stimulated suicide of mature T-cells, or both. The secreted isoforms 2 to 6 block apoptosis (in vitro). {ECO:0000269PubMed:19118384, ECO:0000269PubMed:7533181}.

Disease Associations

Autoimmune lymphoproliferative syndrome 1A (ALPS1A) [MIM:601859]: A disorder of apoptosis that manifests in early childhood and results in the accumulation of autoreactive lymphocytes. It is characterized by non-malignant lymphadenopathy with hepatosplenomegaly, and autoimmune hemolytic anemia, thrombocytopenia and neutropenia. {ECO:0000269PubMed:10090885, ECO:0000269PubMed:10340403, ECO:0000269PubMed:10515860, ECO:0000269PubMed:11418480, ECO:0000269PubMed:17336828, ECO:0000269PubMed:7540117, ECO:0000269PubMed:8929361, ECO:0000269PubMed:9028321, ECO:0000269PubMed:9028957, ECO:0000269PubMed:9322534, ECO:0000269PubMed:9821419, ECO:0000269PubMed:9927496}. Note=The disease is caused by mutations affecting the gene represented in this entry.

Tissue Specificity

Isoform 1 and isoform 6 are expressed at equal levels in resting peripheral blood mononuclear cells. After activation there is an increase in isoform 1 and decrease in the levels of isoform 6. {ECO:0000269PubMed:7575433}.
