General annotation (Comments)

Function	Adapter protein and signal transducer that links members of the tumor necrosis factor receptor family to different signaling pathways by association with the receptor cytoplasmic domain and kinases. Seems to be involved in activation of NF-kappa-B and JNK and in apoptosis. Is regulated by TANK/ITRAF which competes with TNFRSF5/CD40 for binding. Seems to play a role T-cell dependent immune responses.
Subunit structure	Homotrimer Probable. Heteromer with TRAF5 By similarity. Binds to TNFRSF5/CD40. Associates with LTBR/TNFRSF3, TNFRSF4, TNFRSF8/CD30, TNFRSF17/BCMA and EDAR, MAP3K5, MAP3K14, and TRAF-interacting protein TRIP and TRAF and TNF receptor associated protein TTRAP. Binds to TANK/ITRAF and TRAF3IP1. Interacts with TICAM1 By similarity. Interacts with OTUD5.
Subcellular location	CytoplasmProbable.
Domain	The MATH/TRAF domain binds to receptor cytoplasmic domains.
Sequence similarities	Contains 1 MATH domain. Contains 1 RING-type zinc finger. Contains 2 TRAF-type zinc fingers.
