Summary

FASLG (Fas ligand, HGNC:11936) is a protein-coding gene on chromosome 1q24.3, encoding Tumor necrosis factor ligand superfamily member 6 (P48023). Cytokine that binds to TNFRSF6/FAS, a receptor that transduces the apoptotic signal into cells.

This gene is a member of the tumor necrosis factor superfamily. The primary function of the encoded transmembrane protein is the induction of apoptosis triggered by binding to FAS. The FAS/FASLG signaling pathway is essential for immune system regulation, including activation-induced cell death (AICD) of T cells and cytotoxic T lymphocyte induced cell death. It has also been implicated in the progression of several cancers. Defects in this gene may be related to some cases of systemic lupus erythematosus (SLE). Alternatively spliced transcript variants have been described.

Function. Cytokine that binds to TNFRSF6/FAS, a receptor that transduces the apoptotic signal into cells. Involved in cytotoxic T-cell-mediated apoptosis, natural killer cell-mediated apoptosis and in T-cell development. Initiates fratricidal/suicidal activation-induced cell death (AICD) in antigen-activated T-cells contributing to the termination of immune responses. TNFRSF6/FAS-mediated apoptosis also has a role in the induction of peripheral tolerance. Binds to TNFRSF6B/DcR3, a decoy receptor that blocks apoptosis. Induces FAS-mediated activation of NF-kappa-B, initiating non-apoptotic signaling pathways. Can induce apoptosis but does not appear to be essential for this process. Cytoplasmic form induces gene transcription inhibition.

Subcellular location. Cell membrane. Cytoplasmic vesicle lumen. Lysosome lumen Secreted Nucleus.

Post-translational modifications. The soluble form derives from the membrane form by proteolytic processing. The membrane-bound form undergoes two successive intramembrane proteolytic cleavages. The first one is processed by ADAM10 producing an N-terminal fragment, which lacks the receptor-binding extracellular domain. This ADAM10-processed FasL (FasL APL) remnant form is still membrane anchored and further processed by SPPL2A that liberates the FasL intracellular domain (FasL ICD). FasL shedding by ADAM10 is a prerequisite for subsequent intramembrane cleavage by SPPL2A in T-cells. N-glycosylated. Glycosylation enhances apoptotic activity. Phosphorylated by FGR on tyrosine residues; this is required for ubiquitination and subsequent internalization. Monoubiquitinated.

Disease relevance. 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. The disease is caused by variants affecting the gene represented in this entry.

Similarity. Belongs to the tumor necrosis factor family.

Enriched among interaction partners

Reactome pathways and GO biological processes over-represented among this gene’s 81 IntAct physical interaction partners (hypergeometric vs the genome-wide background, BH-FDR, gene-set size 15–500, ranked by fold). A functional readout of the neighbourhood — distinct from this gene’s own memberships above, and biased toward well-studied / hub proteins, so read it as themes rather than proof.
