FunctionENT3_YEAST Involved in the recruitment of clathrin to the Golgi network and endosomes to form clathrin coated vesicles. Plays a role in the trafficking of clathrin between the Golgi network and endosomes. Binds to membranes enriched in phosphatidylinositol-3,5-bisphosphate (PtdIns(3,5)P2) and, in association with VPS27, is involved in protein sorting at the multivesicular body (MVB).[1] [2] Publication Abstract from PubMedSNARE proteins are crucial for membrane fusion in vesicular transport. To ensure efficient and accurate fusion, SNAREs need to be sorted into different budding vesicles. This process is usually regulated by specific recognition between SNAREs and their adaptor proteins. How different pairs of SNAREs and adaptors achieve their recognition is unclear. Here, we report the recognition between yeast SNARE Vti1p and its adaptor Ent3p derived from three crystal structures. Surprisingly, this yeast pair Vti1p/Ent3p interacts through a distinct binding site compared to their homologues vti1b/epsinR in mammals. An opposite surface on Vti1p_Habc domain binds to a conserved area on the epsin N-terminal homology (ENTH) domain of Ent3p. Two-hybrid, in vitro pull-down and in vivo experiments indicate this binding interface is important for correct localization of Vti1p in the cell. This previously undescribed discovery that a cargo and adaptor pair uses different binding sites across species suggests the diversity of SNARE-adaptor recognition in vesicular transport. Epsin N-terminal homology domains bind on opposite sides of two SNAREs.,Wang J, Gossing M, Fang P, Zimmermann J, Li X, von Mollard GF, Niu L, Teng M Proc Natl Acad Sci U S A. 2011 Jul 26;108(30):12277-82.
