Research Backgrounds

Function:

Regulates pathways leading to the activation of NF-kappa-B and MAP kinases, and plays a central role in the regulation of B-cell survival. Part of signaling pathways leading to the production of cytokines and interferon. Required for normal antibody isotype switching from IgM to IgG. Plays a role T-cell dependent immune responses. Plays a role in the regulation of antiviral responses. Is an essential constituent of several E3 ubiquitin-protein ligase complexes. May have E3 ubiquitin-protein ligase activity and promote 'Lys-63'-linked ubiquitination of target proteins. Inhibits activation of NF-kappa-B in response to LTBR stimulation. Inhibits TRAF2-mediated activation of NF-kappa-B. Down-regulates proteolytic processing of NFKB2, and thereby inhibits non-canonical activation of NF-kappa-B. Promotes ubiquitination and proteasomal degradation of MAP3K14.

PTMs:

Undergoes 'Lys-48'-linked polyubiquitination, leading to its proteasomal degradation in response to signaling by TNFSF13B, TLR4 or through CD40. 'Lys-48'-linked polyubiquitinated form is deubiquitinated by OTUD7B, preventing TRAF3 proteolysis and over-activation of non-canonical NF-kappa-B. Undergoes 'Lys-63'-linked ubiquitination during early stages of virus infection, and 'Lys-48'-linked ubiquitination during later stages. Undergoes both 'Lys-48'-linked and 'Lys-63'-linked ubiquitination in response to TLR3 and TLR4 signaling. Deubiquitinated by OTUB1, OTUB2 and OTUD5.

Subcellular Location:

Cytoplasm. Endosome. Mitochondrion.
Note: Undergoes endocytosis together with TLR4 upon LPS signaling (By similarity). Associated with mitochondria in response to virus.

Subunit Structure:

Homotrimer. Heterotrimer with TRAF2 and TRAF5. Interacts with LTBR/TNFRSF3, TNFRSF4, TNFRSF5/CD40, TNFRSF8/CD30, TNFRSF13C TNFRSF17/BCMA, TLR4 and EDAR. Interacts with MAP3K5, MAP3K14, TRAIP/TRIP, TDP2/TTRAP, TANK/ITRAF and TRAF3IP1. Interaction with TNFRSF5/CD40 is modulated by TANK/ITRAF, which competes for the same binding site. Interacts with TICAM1. Interacts with TRAFD1. Interacts with OTUB1, OTUB2 and OTUD5. Interacts with RNF216, MAVS, OPTN and TBK1. Identified in a complex with TRAF2, MAP3K14 and BIRC3. Interacts with BIRC2 and BIRC3. Upon exposure to bacterial lipopolysaccharide (LPS), recruited to a transient complex containing TLR4, TRAF3, TRAF6, IKBKG, MAP3K7, MYD88, TICAM1, BIRC2, BIRC3 and UBE2N (By similarity). Interacts with Epstein-Barr virus protein LMP1. Interacts (via RING-type zinc finger domain) with SRC. Interacts with CARD14. Interacts (via MATH domain) with PTPN22; the interaction promotes TRAF3 polyubiquitination.

Family&Domains:

The MATH/TRAF domain binds to receptor cytoplasmic domains.

The Ring-type zinc finger domain is required for its function in down-regulation of NFKB2 proteolytic processing.

Belongs to the TNF receptor-associated factor family. A subfamily.
