The mechanism of retrograde trafficking by retromer

Obiettivo

Transportation of proteins and lipids between membrane-enclosed organelles by vesicle formation is a fundamental task in eukaryote cells. The least understood protein complex involved in membrane remodelling for vesiculation, but with a wide range of medical implications, is the retromer complex.

The objective of this proposal is:
First, to identify the mechanistic principles of membrane bending and scission by retromer, and second to characterize temporal and morphological aspects of retromer and cargo molecules (Shiga toxin (STx) and Alzheimer’s amyloid-beta-cleaving enzyme (BACE)).

I will exploit two approaches:
First, in vitro reconstitution of the retromer complex using giant unilamellar vesicles to deploy biophysical methods.
Second, I will provide a molecular choreography and anatomy of retrograde transport of STx, BACE and retromer by implementing a new imaging technique, structured-illumination microscopy combined with single particle tracking.

The proposed interdisciplinary research will break new ground for membrane mechanics and trafficking of disease related cargo molecules.
