This signalling hub features the rapid recruitment of TRADD and RIPK1 after engagement of TNFR1 by TNF for the formation of complex I, followed by timed disassembly for transition into downstream signalling complexes, but the mechanism driving the dynamic reversibility of complex I remains unclear. Here we captured the assembly core of complex I and determined its cryo-electron microscopy structure, showing a pentameric fibre comprising 31 DDs, with a single layer of a TRADD-DD pentamer sandwiched between multiple layers of TNFR1-DD and RIPK1-DD homopentamers. Structural analysis revealed a strong opposing electric dipole moment (EDM) generated by RIPK1-DD oligomerization relative to that of TNFR1-DD and TRADD-DD. Structure-guided mutagenesis in TNFR1-TRADD-RIPK1 pentameric fibres altering the EDM without affecting DD oligomerization demonstrated the role and mechanism of EDM in driving the dynamic reversibility mediating the rapid assembly and disassembly of complex I. Our study demonstrates a role for long-range interactions mediated by protein EDMs in driving the assembly and disassembly of super-signalling complex I for promoting NF-κB signalling. | ||||||||||||||||||||||||||||||
