12 Provides Reactome curated referenced GO annotations where they do not currently exist in GOA Provides stronger experimental evidence for GOA annotation supported only by computational inferences. Improves the accuracy and consistency of the annotations in both databases. Collaboration between GO and Reactome Reactome pathway --> GO Biological Processes Reactome catalyst activity --> GO Molecular Function Cellular location of Reactome reactions --> GO Cellular Compartment Location of Reactome reaction input/output etc.-->GO Cellular Compartment The GO consortium will soon cross-reference GO terms back to their corresponding concepts in Reactome. Cross-references between Reactome and GO Comparison and sharing of annotations between Reactome and GOA

17 Other species in Reactome Primary focus: manual curation of human reactions Some human reactions are (manually) inferred from other species (lack of experimental evidence in human) For each release a set of electronically inferred reactions is produced based on orthology data (from human to other species)

21 Reaction inference Orthologue mapping based on the OrthoMCL system for a set of diverse, well-annotated species Includes (recent) paralogues Complex threshold (not all components of a complex need to have orthologues)
