Query author contributions in Reactome
Reactome depends on collaboration between our curation team and outside experts to assemble and peer-review its pathway modules. The integration of ORCID within Reactome enables us to meet a key challenge with authoring, curating and reviewing biological information by incentivizing and crediting the external experts that contribute their expertise and time to the Reactome curation process. More information is available at ORCID and Reactome.
If you have an ORCID ID that is not listed on this page, please forward this information to us and we will update your Reactome pathway records.

| comment | FUNCTION E3 ubiquitin ligase that, together with UBE2N and UBE2V1, mediates the synthesis of 'Lys-63'-linked-polyubiquitin chains conjugated to proteins, such as ECSIT, IKBKG, IRAK1, AKT1 and AKT2 (PubMed:11057907, PubMed:18347055, PubMed:19465916, PubMed:19713527, PubMed:27746020, PubMed:31620128). Also mediates ubiquitination of free/unanchored polyubiquitin chain that leads to MAP3K7 activation (PubMed:19675569). Leads to the activation of NF-kappa-B and JUN (PubMed:16378096, PubMed:17135271, PubMed:17703191). Seems to also play a role in dendritic cells (DCs) maturation and/or activation (By similarity). Represses c-Myb-mediated transactivation, in B-lymphocytes (PubMed:18093978, PubMed:18758450). Adapter protein that seems to play a role in signal transduction initiated via TNF receptor, IL-1 receptor and IL-17 receptor (PubMed:12140561, PubMed:19825828, PubMed:8837778). Regulates osteoclast differentiation by mediating the activation of adapter protein complex 1 (AP-1) and NF-kappa-B, in response to RANK-L stimulation (By similarity). Together with MAP3K8, mediates CD40 signals that activate ERK in B-cells and macrophages, and thus may play a role in the regulation of immunoglobulin production (By similarity). Acts as a regulator of the JNK and NF-kappa-B signaling pathways by initiating assembly of heterotypic 'Lys-63'-/'Lys-48'-linked branched ubiquitin chains that are then recognized by TAB2: TRAF6 catalyzes initial 'Lys-63'-linked-polyubiquitin chains that are then branched via 'Lys-48'-linked polyubiquitin by HUWE1 (PubMed:27746020). 'Lys-63'-/'Lys-48'-linked branched ubiquitin chains protect 'Lys-63'-linkages from CYLD deubiquitination (PubMed:27746020). Participates also in the TCR signaling by ubiquitinating LAT (PubMed:23514740, PubMed:25907557).CATALYTIC ACTIVITY S-ubiquitinyl-[E2 ubiquitin-conjugating enzyme]-L-cysteine + [acceptor protein]-L-lysine = [E2 ubiquitin-conjugating enzyme]-L-cysteine + N(6)-ubiquitinyl-[acceptor protein]-L-lysine.PATHWAY Protein modification; protein ubiquitination.SUBUNIT Homotrimer. Homooligomer. N-terminal region is dimeric while C-terminal region is trimeric; maybe providing a mode of oligomerization. Upon IL1B treatment, forms a complex with PELI1, IRAK1, IRAK4 and MYD88; this complex recruits MAP3K7/TAK1, TAB1 and TAB2 to mediate NF-kappa-B activation. Direct binding of SMAD6 to PELI1 prevents the complex formation and hence negatively regulates IL1R-TLR signaling and eventually NF-kappa-B-mediated gene expression. Binds to TNFRSF5/CD40 and TNFRSF11A/RANK. Associates with NGFR, TNFRSF17, IRAK2, IRAK3, RIPK2, MAP3K1, MAP3K5, MAP3K14, CSK, TRAF, TRAF-interacting protein TRIP and TNF receptor associated protein TDP2. Interacts with IL17R. Interacts with SQSTM1 bridging NTRK1 and NGFR. Forms a ternary complex with SQSTM1 and PRKCZ (By similarity). Interacts with PELI2 and PELI3. Binds UBE2V1. Interacts with TAX1BP1; this interaction mediates deubiquitination of TRAF6 and inhibition of NF-kappa-B activation (PubMed:10920205, PubMed:17703191). Interacts with ZNF675. Interacts with ARRB1 and ARRB2. Interacts with MAP3K7 and TAB1/MAP3K7IP1; during IL-1 signaling. Interacts with UBE2N. Interacts with TGFBR1, HDAC1 and RANGAP1. Interacts with AKT1, AKT2 and AKT3. Interacts (via TRAF domains) with NUMBL (via C-terminal). Interacts with RBCK1. Interacts with LIMD1 (via LIM domains) (By similarity). Interacts with RSAD2/viperin (By similarity). Interacts (via C-terminus) with EIF2AK2/PKR (via the kinase catalytic domain) (By similarity). Interacts with ZFAND5. Interacts with IL1RL1. Interacts with TRAFD1. Interacts with AJUBA. Interacts with MAVS/IPS1. Interacts (via TRAF domains) with DYNC2I2 (via WD domains). Interacts with IFIT3 (via N-terminus). Interacts with TICAM2. Interacts with CARD14. Interacts with CD40 and MAP3K8; the interaction is required for ERK activation (By similarity). Interacts with TICAM1 and this interaction is enhanced in the presence of WDFY1 (PubMed:25736436). Interacts with TANK; this interaction increases in response to DNA damage (PubMed:25861989). Interacts with USP10; this interaction increases in response to DNA damage (PubMed:25861989). Interacts with ZC3H12A; this interaction increases in response to DNA damage and is stimulated by TANK (PubMed:25861989). Interacts with WDFY3 (By similarity). Interacts with TRIM13 (PubMed:28087809). Interacts with GPS2 (By similarity). Interacts (via C-terminus) with SASH1 (PubMed:23776175). Interacts with LRRC19 (PubMed:25026888). Interacts with IL17RA and TRAF3IP2. Interacts with TOMM70 (PubMed:20628368). Interacts with AMBRA1; interaction is required to mediate 'Lys-63'-linked ubiquitination of ULK1 (PubMed:23524951). Interacts with CRBN; this interaction inhibits TLR4-mediated signaling by preventing TRAF6-mediated ubiquitination of ECSIT (PubMed:31620128).SUBCELLULAR LOCATION Found in the nuclei of some aggressive B-cell lymphoma cell lines as well as in the nuclei of both resting and activated T- and B-lymphocytes. Found in punctate nuclear body protein complexes. Ubiquitination may occur in the cytoplasm and sumoylation in the nucleus. RSAD2/viperin recruits it to the lipid droplet (By similarity).TISSUE SPECIFICITY Expressed in heart, brain, placenta, lung, liver, skeletal muscle, kidney and pancreas.DOMAIN The coiled coil domain mediates homo- and hetero-oligomerization.DOMAIN The MATH/TRAF domain binds to receptor cytoplasmic domains.PTM Sumoylated on Lys-124, Lys-142 and Lys-453 with SUMO1.PTM Polyubiquitinated on Lys-124 by TRAF3IP2; after cell stimulation with IL17A (PubMed:19825828). Polyubiquitinated on Lys-124; after cell stimulation with IL1B or TGFB. This ligand-induced cell stimulation leads to dimerization/oligomerization of TRAF6 molecules, followed by auto-ubiquitination which involves UBE2N and UBE2V1 and leads to TRAF6 activation. This 'Lys-63' site-specific poly-ubiquitination appears to be associated with the activation of signaling molecules. Endogenous autoubiquitination occurs only for the cytoplasmic form. Deubiquitinated by USP10 in a TANK-dependent manner, leading to the negative regulation of NF-kappaB signaling upon DNA damage (PubMed:25861989). LRRC19 induces 'Lys-63' ubiquitination (PubMed:25026888). Ubiquitinated at Lys-319 by the SCF(FBXL2) complex, leading to its degradation by the proteasome (By similarity).PTM (Microbial infection) Deubiquitinated by Epstein-Barr virus BPLF1 on both 'Lys-48' and 'Lys-63'-linked ubiquitin chains; leading to NF-kappa-B signaling inhibition.SIMILARITY Belongs to the TNF receptor-associated factor family. A subfamily. |
