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? Check out the baseball fields: A baseball field in the park would be one of those functional interaction islands upon which proteins – the players – group themselves for a particular cellular function – in this case, the baseball game. If the players leave the field, they lose their ability to function in this way. It's all about baseball & functional nanoscale organization of the surfaceome!"Surfaceome nanoscale organization and extracellular interaction networks"
Based on a specific biomedical question we measure millions of spectra derived from biospecimen using mass spectrometry.
Using complex bioinformatic pipelines & statistical models we integrate the data and establish the proteotype of a biospecimen.
We analyze the spatiotemporal dynamics of the biological system/proteotype under perturbation and generate hypotheses in order to explain the phenotype and molecular processes involved.
Using a variety of Systems Biology technologies we validate our findings and turn raw data into new biological insights & basic knowledge on how cells communicate.

Our review/perspective on "Surfaceome Nanoscale Organization and Extracellular Interaction Networks" in "Current Opinion in Chemical Biology" is now online! Cell surface exposed proteins, termed the surfaceome, are the gatekeepers between the intra- and extracellular signaling networks, translating extracellular cues into intracellular responses and vice versa.Bausch-Fluck et al., Current Opinion in Chemical Biology, 2018. - ETH News release & Commentary (Putting a face on a cell surface) by HP Ruegg!
The in silico human surfaceome published in PNAS! We applied a machine-learning approach utilizing domain-specific features to develop the accurate surfaceome predictor SURFY and used it to define the human in silico surfaceome of 2,886 proteins.Bausch-Fluck et al., The in silico human surfaceome, 2018.
