Abstract

In this project we plan to develop new analytical methods for in cell crosslinking mass spectrometry and also develop new computational methods to process, but also model protein complexes using the XL-MS data. We plan to use our new methods to identify the macromolecular machines mediating Fast Endophilin-Mediated Endocytosis (FEME) vesicle formation in vivo, a pathway that we have recently identified.
