Protein Structure

UniProt Annotation

Function

Cytokine that binds to TNFRSF6/FAS, a receptor that transduces the apoptotic signal into cells. May be involved in cytotoxic T-cell mediated apoptosis and in T-cell development. TNFRSF6/FAS-mediated apoptosis may have a role in the induction of peripheral tolerance, in the antigen-stimulated suicide of mature T-cells, or both. Binding to the decoy receptor TNFRSF6B/DcR3 modulates its effects. {ECO:0000269PubMed:17557115}.The FasL intracellular domain (FasL ICD) cytoplasmic form induces gene transcription inhibition. {ECO:0000269PubMed:17557115}.

Subcellular Localization

Cell membrane; Single-pass type II membrane protein. Cytoplasmic vesicle lumen. Lysosome lumen. Note=Is internalized into multivesicular bodies of secretory lysosomes after phosphorylation by FGR and monoubiquitination. Colocalizes with the SPPL2A protease at the cell membrane.Tumor necrosis factor ligand superfamily member 6, soluble form: Secreted {ECO:0000250}. Note=May be released into the extracellular fluid, probably by cleavage form the cell surface. {ECO:0000250}.FasL intracellular domain: Nucleus. Note=The FasL ICD cytoplasmic form is translocated into the nucleus.

Disease Associations

Autoimmune lymphoproliferative syndrome 1B (ALPS1B) [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:8787672}. Note=The disease is caused by mutations affecting the gene represented in this entry.
