The guided-entry of tail-anchored proteins (GET) pathway is a post-translational targeting route to the endoplasmic reticulum (ER). Upon glucose withdrawal, the soluble GET proteins re-localize to dynamic cytosolic foci, here termed GET bodies. Our data reveal that the pre-targeting complex components, Sgt2 and the Get4-Get5 heterodimer, and the Get3 ATPase play important roles in the assembly of these structures in Saccharomyces cerevisiae. More specifically, the TPR region of Sgt2 is required as a GET body scaffold. Systematic compositional analyses of GET bodies reveal their chaperone-rich nature and the presence of numerous proteins involved in metabolic processes. Temporal analyses of GET body assembly demonstrate the sequential recruitment of different chaperones, and we discover the requirement of Sis1 and Sti1 for maintaining the dynamic properties of these structures. In vivo, NADH derived from the oxidation of ethanol to acetaldehyde can induce GET body disassembly in a reaction depending on the alcohol dehydrogenase Adh2 and in vitro, addition of NADH resolves GET bodies. This suggests a mechanistic basis for their formation and disassembly in response to the metabolic shift caused by glucose withdrawal and re-addition.
