    The multifunctional virion protein 35 (VP35) of ebolaviruses is a critical determinant of virulence and pathogenesis indispensable for viral replication and host innate immune evasion. Essential for VP35 function is homo-oligomerization via a coiled-coil motif. Here we report crystal structures of VP35 oligomerization domains from the prototypic Ebola virus (EBOV) and the non-pathogenic Reston virus (RESTV), together with a comparative biophysical characterization of the domains from all known species of the Ebolavirus genus. EBOV and RESTV VP35 oligomerization domains form bipartite parallel helix bundles with a canonical coiled coil in the N-terminal half and increased plasticity in the highly conserved C-terminal half. The domain assembles into trimers and tetramers in EBOV, whereas it exclusively forms tetramers in all other ebolavirus species. Substitution of coiled-coil leucine residues critical for immune antagonism leads to aberrant oligomerization. A conserved arginine involved in inter-chain salt bridges stabilizes the VP35 oligomerization domain and modulates between coiled-coil oligomeric states.
