Abstract

In this course you will learn to measure, integrate, analyze and validate the cellular surfaceome as a complex information gateway connecting the intracellular to the extracellular interactome. You will apply next generation technologies at the interface of biology, chemistry, medicine and bioinformatics to establish the surfaceome proteotype and its signaling interaction networks.

Objective

"If a cell surface molecule such as the B cell receptor would have the size of a human being, then the cell surface of a B cell would have roughly the size of three times NYC Central Park." How many people/proteins/proteoforms reside in this space ("Surfaceome")? Similar to humans, proteins don't act alone. Function is encoded in dynamic protein-protein interactions. How are these proteoforms organized in signaling islands/networks in order to fulfill specific cellular functions ("Interactome")? What are the ligands interacting with the surfaceome to communicate information from other cells & tissues in the body? What goes wrong in these signaling islands if we get sick? In this course you will learn to measure, integrate, analyze and validate the cellular surfaceome and its signaling islands as a complex information gateway connecting the intracellular to the extracellular interactome. You will apply next generation technologies at the interface of biology, chemistry, medicine and bioinformatics to generate unprecedented data to establish the surfaceome proteotype and its signaling interaction networks. This digital proteotype data layer provides the basis for generating qualitative and quantitative surfaceome models explaining how molecular nanoscale organization influences cellular signaling and biological function.
