Gene Description

FADD is a cytosolic death-fold adaptor that couples activated death receptors to initiator caspase assemblies. Its C-terminal death domain binds receptor or receptor-associated death domains at FAS, TRAIL, and TNFR1 signaling platforms, while its N-terminal death effector domain recruits and oligomerizes CASP8, CASP10, and CFLAR-family partners to form death-inducing signaling complexes and related cytosolic complexes. Through this scaffold role, FADD initiates extrinsic apoptotic signaling, contributes to RIPK1/caspase-8 ripoptosome decisions between apoptosis and necroptosis, and has a secondary adaptor role in MAVS/RIG-I-like receptor antiviral signaling.

GO:0033612 receptor serine/threonine kinase binding
IEA
GO_REF:0000107
REMOVE
Summary: Receptor serine/threonine kinase binding (IEA), transferred from rat Fadd, where the annotated partners are the receptor-interacting kinases RIPK1 and RIPK3 rather than a receptor kinase.
Reason: The row is transferred from rat Fadd, where the term rests on a physical-interaction annotation from a study of FADD in RIPK1- and RIPK3-dependent programmed necrosis of cardiomyocytes (PMID:26038570). RIPK1 and RIPK3 are receptor-interacting serine/threonine kinases, cytosolic kinases recruited to death-receptor complexes, whereas this term is defined as binding to a receptor that itself possesses protein serine/threonine kinase activity, such as the TGF-beta receptor family. The source annotation therefore uses a term that does not describe the interaction it records, and nothing indicates that FADD binds a receptor serine/threonine kinase. The FADD-RIPK1 interaction itself is real but is not what this term states.

This row reports the same FADD-FADD interaction from a yeast two-hybrid interaction-profiling study of disease variants; a systematic screen adds little mechanistic detail, but its result agrees with the directly demonstrated self-association and nothing contradicts it.

Summary: The TWEAK/FN14 evidence supports extrinsic apoptotic signaling without establishing a specific death-domain receptor subclass.
Reason: Extrinsic apoptotic signaling is a better scope than positive regulation of the whole process for this contextual TNFRSF12A/TNF pathway.

Core Functions

FADD bridges death-domain receptor platforms to CASP8/CASP10-containing DED assemblies to form death-inducing signaling complexes that initiate extrinsic apoptotic signaling.

Supporting Evidence:
  • PMID:24025841
    FADD then recruits pro-caspase-8 forming the death-inducing signalling complex (DISC)
  • PMID:16762833
    self-association surface necessary to form a productive complex
  • PMID:9184224
    Here we show that FLICE binds to FADD through

Suggested Questions for Experts

Q: Should FADD annotations to broad lymphoid-organ, T-cell, and antiviral phenotypes be collapsed into a small set of curated adaptor activities plus GO-CAM inputs for FAS, TRAIL, TNFR1, MAVS, and TLR/ripoptosome complexes?

Q: Should GO distinguish receptor-proximal death-inducing signaling complexes from cytosolic complex-II and ripoptosome variants more explicitly for FADD, CASP8, CFLAR, TRADD, and RIPK1 annotations?

Suggested Experiments

Experiment: For generic FADD interaction partners that remain in IntAct-only protein-binding imports, perturb the interaction surface in endogenous FADD and assay receptor-proximal DISC assembly, CASP8 recruitment, CASP8 activation, and death-receptor apoptosis before making partner-specific GO annotations.
