THE CRYSTAL STRUCTURE OF THE BET3-TRS31 HETERODIMER.
Overview
Transport protein particle (TRAPP) I is a multisubunit vesicle tethering, factor composed of seven subunits involved in ER-to-Golgi trafficking. The, functional mechanism of the complex and how the subunits interact to form, a functional unit are unknown. Here, we have used a multidisciplinary, approach that includes X-ray crystallography, electron microscopy, biochemistry, and yeast genetics to elucidate the architecture of TRAPP I., The complex is organized through lateral juxtaposition of the subunits, into a flat and elongated particle. We have also localized the site of, guanine nucleotide exchange activity to a highly conserved surface, encompassing several subunits. We propose that TRAPP I attaches to Golgi, membranes with its large flat surface containing many highly conserved, residues and forms a platform for protein-protein interactions. This study, provides the most comprehensive view of a multisubunit vesicle tethering, complex to date, based on which a model for the function of this complex, involving Rab1-GTP and long, coiled-coil tethers, is presented.
