Protein subcellular localization is tightly controlled and intimately linked to protein function in health and disease. Capturing the spatial proteome — that is, the localizations of proteins and their dynamics at the subcellular level — is therefore essential for a complete understanding of cell biology. Owing to substantial advances in microscopy, mass spectrometry and machine learning applications for data analysis, the field is now mature for proteome-wide investigations of spatial cellular regulation. Studies of the human proteome have begun to reveal a complex architecture, including single-cell variations, dynamic protein translocations, changing interaction networks and proteins localizing to multiple compartments. Furthermore, several studies have successfully harnessed the power of comparative spatial proteomics as a discovery tool to unravel disease mechanisms. We are at the beginning of an era in which spatial proteomics finally integrates with cell biology and medical research, thereby paving the way for unbiased systems-level insights into cellular processes. Here, we discuss current methods for spatial proteomics using imaging or mass spectrometry and specifically highlight global comparative applications. The aim of this Review is to survey the state of the field and also to encourage more cell biologists to apply spatial proteomics approaches.

- Dynamic protein translocation
Translocation describes the movement of a protein between cellular compartments. Dynamic translocation refers to a constant change in translocation activity.
- Multimodal organellar distribution
Refers to the distribution of proteins that simultaneously localize to multiple compartments within a cell.
- Affinity reagents
Molecules, such as an antibody, protein, peptide or nucleic acid, that bind specifically to a target protein to enable the identification, visualization, capture or modulation of the target protein or its activity.
- Tandem mass tag multiplexing
A strategy for quantitative proteomic analyses. Peptides from multiple samples are labelled with different mass tags, pooled and analysed as a single sample by mass spectrometry. The tags can be distinguished by their mass and thus enable the simultaneous, relative quantification of peptide and protein abundances across several samples.
Describes the process of partitioning a digital image into segments that represent, for example, a cell or a nucleus.
- Citizen science
Public participation in scientific research.
- Tagged yeast libraries
Genome-wide libraries of yeast cells, each expressing a protein fused to a fluorescent reporter protein (such as GFP).
Integration of proteomics, transcriptomics and genomics for the discovery and identification of peptides using mass spectrometry. Practically, DNA or RNA sequence information is used to provide an experiment-specific or cell-type-specific tailored database for proteomic protein identification rather than a generic organism-specific database.
