Resource: The COMPARTMENTS database on protein subcellular localization

Together with collaborators in the groups of Se├ín O’Donoghue and Reinhard Schneider, my group has recently launched a new web-accessible database named COMPARTMENTS.

COMPARTMENTS unifies subcellular localization evidence from many sources by mapping all proteins and compartments to their STRING identifiers and Gene Ontology terms, respectively. We import curated annotations from UniProtKB and model organism databases and assign confidence scores to them based on their evidence codes. For human proteins, we similarly import and score evidence from The Human Protein Atlas. COMPARTMENTS also uses text mining to derive subcellular localization evidence from co-occurrence of proteins and compartments in Medline abstracts. Finally, we precompute subcellular localization predictions with the sequence-based methods WoLF PSORT and YLoc. For further details, please refer to our recently published paper entitled “COMPARTMENTS: unification and visualization of protein subcellular localization evidence”.

To provide a simple overview of all this information, we visualize the combined localization evidence for each protein onto a schematic of an animal, fungal, or plant cell:
