Dissecting the Spatiotemporal Subcellular Distribution of the Human Proteome

Seminar: BioE Seminars: Seminars of interest | August 29 | 12-1 p.m. | 106 Stanley Hall

Emma Lundberg, KTH Royal Institute of Technology

Bioengineering (BioE)

Compartmentalization of biological reactions is an important mechanism to allow multiple cellular reactions to occur in parallel. Resolving the spatial distribution of the human proteome at a subcellular level increases our understanding of human biology and disease. We have generated a high-resolution map of the subcellular distribution of the human proteome as part of the open access Human Protein Atlas database. We have shown that as much as half of all proteins localize to multiple compartments. Such proteins may have context specific functions and ‘moonlight’ in different parts of the cell, thus increasing the functionality of the proteome and the complexity of the cell from a systems perspective. Furthermore, I will present unpublished data on the extent of single cell variations of the human proteome, in correlation to cell cycle progression and other deterministic factors. Finally, I will show how 300,000 gamers can augment machine learning approaches for pattern recognition in microscope images (EVE Online Project Discovery). In summary, I will demonstrate the importance of spatial proteomics data for improved single cell biology., 5106663362
