E3 ubiquitin ligase that, together with UBE2N and UBE2V1, mediates the synthesis of 'Lys-63'-linked-polyubiquitin chains conjugated to proteins, such as IKBKG, AKT1 and AKT2. Also mediates ubiquitination of free/unanchored polyubiquitin chain that leads to MAP3K7 activation (By similarity). Leads to the activation of NF-kappa-B and JUN. May be essential for the formation of functional osteoclasts. Seems to also play a role in dendritic cells (DCs) maturation and/or activation. Represses c-Myb-mediated transactivation, in B lymphocytes. Adapter protein that seems to play a role in signal transduction initiated via TNF receptor, IL-1 receptor and IL-17 receptor.
Specificity
Natural and recombinant Mouse TNF receptor-associated factor 6
Homotrimer (By similarity). Homooligomer (By similarity). N-terminal region is dimeric while C-terminal region is trimeric; maybe providing a mode of oligomerization. Binds to TNFRSF5/CD40 and TNFRSF11A/RANK (By similarity). Associates with NGFR, TNFRSF17, IRAK1, IRAK2, IRAK3, IRAK4, PELI1, PELI2, PELI3, RIPK2, MAP3K1, MAP3K5, MAP3K14, CSK, TRAF, TRAF-interacting protein TRIP and TNF receptor associated protein TDP2. Binds UBE2V1. Interacts with MAVS/IPS1. Interacts with TAX1BP1 (By similarity). Interacts with IL17R. Interacts with SQSTM1 bridging NTRK1 and NGFR. Forms a ternary complex with SQSTM1 and PRKCZ.
