Using Models to (Re-)Design Synthetic Circuits.

Author(s): McCallum G, Potvin-Trottier L

Mathematical models play an important role in the design of synthetic gene circuits, by guiding the choice of biological components and their assembly into novel gene networks. Here, we present a guide for biologists to build and utilize models of gene netw...

Abstract

SNARE-mediated membrane fusion is required for membrane trafficking as well as organelle biogenesis and homeostasis. The membrane fusion reaction involves sequential formation of hemifusion intermediates, whereby lipid monolayers partially mix on route to complete bilayer merger. Studies of the Saccharomyces cerevisiae lysosomal vacuole have revealed many of the fundamental mechanisms that drive the membrane fusion process, as well as features unique to organelle fusion. However, until recently, it has not been amenable to electron microscopy methods that have been invaluable for studying hemifusion in other model systems. Herein, we describe a method to visualize hemifusion intermediates during homotypic vacuole membrane fusion in vitro by transmission electron microscopy (TEM), electron tomography, and cryogenic electron microscopy (cryoEM). This method facilitates acquisition of invaluable ultrastructural data needed to comprehensively understand how fusogenic lipids and proteins contribute to SNARE-mediated membrane fusion-by-hemifusion and the unique features of organelle versus small-vesicle fusion.
