Beyond coat assembly, the ENTH domain binds the N-terminal domain of the SNARE vti1b, an interaction conserved to the yeast ortholog Ent3p, which engages multiple SNAREs (Vti1p, Pep12p, Syn8p) and cooperates with them in bidirectional transport between the TGN and the endosome/prevacuole, thereby linking vesicle budding to fusion machinery [#2, #7].
