The endosome at atomic resolution

点击翻译按钮获取中文摘要

The project seeks to improve understanding of intracellular transport. The transport of proteins is essential for controlling the interactions of a cell with its environment, and for regulating a huge number of cell signalling events. The retromer protein complex is a central mediator of intracellular trafficking in organelles called endosomes. It is vital for normal cell homeostasis in all eukaryotic organisms, and is an emerging target for treatment of human neurodegenerative diseases. This project plans to use a combination of cutting-edge X-ray crystallographic and electron microscopy approaches to develop a multi-scale, pseudo-atomic structure of retromer and key regulatory proteins to understand how this multi-component protein machinery is assembled to control intracellular transport.
