ABSTRACTThe endosomal sorting complexes required for transport (ESCRT) mediate various membrane remodeling processes in cells by mechanism that are incompletely understood. Here we combined genetic experiments in budding yeast with site-specific cross-linking to identify rules that govern the self-assembly of individual ESCRT-III proteins into functional ESCRT-III complexes on endosomes. Together with current structural models of ESCRT-III, our findings suggest that, once nucleated, the growing Snf7 protofilament seeds the lateral co-assembly of a Vps24 - Vps2 heterofilament. Both Vps24 and Vps2 use positively charged amino acid residues in their helices α1 to interact with negatively charged amino acids in helix α4 of Snf7 subunits of the protofilament. In the Vps24 - Vps2 heterofilament, the two subunits alternate and interact with each other using hydrophobic interactions between helices α2/α3. The co-assembly of the Vps24 - Vps2 heterofilament restricts the lateral expansion of Snf7 protofilaments and leads the immediate recruitment of the AAA-ATPase Vps4. This self-assembly process of three ESCRT-III subunits results in the formation of a Snf7 protofilament and the co-assembly of a Vps24 - Vps2 heterofilament. This sets the stage for Vps4 recruitment and the subsequent ATP-driven dynamic self-organization of ESCRT-III / Vps4 assemblies and the ensuing membrane budding and scission events.
