FASLG (Fas ligand, CD95L, TNFSF6) is a type II transmembrane TNF-family cytokine. Its trimeric extracellular TNF-homology domain binds the FAS/CD95 death receptor on neighboring cells to assemble a FADD- and initiator-caspase-containing DISC and trigger extrinsic apoptotic signaling during immune homeostasis, cytotoxic lymphocyte killing, activation-induced T-cell death, and peripheral tolerance. The membrane precursor traffics through secretory lysosomes to the cell surface, can be shed to a soluble receptor-binding ectodomain, and can be further cleaved by ADAM10 and SPPL2A to liberate a nuclear FasL intracellular domain with transcriptional effects.

| GO:0005125 cytokine activity | IBA GO_REF:0000033 | ACCEPT | Summary: FASLG is a pro-apoptotic TNF-family cytokine that can trigger FAS-dependent death-receptor signaling.

Reason: FASLG is the extracellular ligand that activates FAS; CASP8 is recruited cytosolically by FADD, so the imported generic protein-binding edge is indirect and should not stand as a FASLG molecular function. |

| GO:0036337 Fas signaling pathway | IDA PMID:7826947 Human Fas ligand: gene structure, chromosomal location and s... | NEW | Summary: FASLG is the cognate TNF-family death ligand that initiates the Fas (CD95) signaling pathway by engaging trimeric FAS receptors at the plasma membrane. Reason: FASLG directly performs the receptor-activating ligand step of the Fas signaling pathway (GO:0036337) by engaging and trimerizing cell-surface FAS/CD95 receptors through its extracellular TNF-homology domain to nucleate the FADD/CASP8 death-inducing signaling complex (PMID:7826947; PMID:9228058). Comparator death-receptor and cytokine ligands are annotated directly to their specific named receptor-signaling pathway terms (e.g. TNFSF10 on GO:0036462 TRAIL-activated apoptotic signaling pathway, IL34 on GO:0061514 interleukin-34-mediated signaling pathway, and C3 on GO:0002430 complement receptor mediated signaling pathway), and corroborating GO-CAM 663d668500001551 already places the downstream receptor and DISC components FAS (P25445), FADD (Q13158), and CASP8 (Q14790) in GO:0036337 while FASLG was annotated only to the broader parent GO:0008625 (extrinsic apoptotic signaling pathway via death domain receptors).

Download this section (compressed HTML)Q: Should Reactome-to-GOA export filter FASLG out of downstream CFLAR:CASP8 and FASLG transcription events so that extracellular-region annotations are sourced only to reactions that actually contain the FASLG protein?
Q: Should recurring IntAct imports of FASLG cytoplasmic-tail trafficking interactions remain uncurated at GO:0005515, or should GO add a FasL-tail adaptor-binding activity only if that activity can be defined more precisely than generic SH3/proline-rich binding?
Experiment: For individual FASLG cytoplasmic-tail interactors from SH3, HuRI, BioPlex, and U2OS cell-map datasets, test endogenous binding in cytotoxic lymphocytes and quantify effects on secretory-lysosome storage, immunological-synapse delivery, FASLG shedding, and FAS-dependent target-cell apoptosis before making partner-specific GO annotations.
