Function
All complexes are manually annotated with a function statement followed by Gene Ontology annotations to the Molecular Function and Biological Process class (where applicable). If applicable, links are provided to ENZYME for enzymes and ligands, antagonists and agonists are listed with links to their reference databases (Figure 7).

A table of cross-references to equivalent complexes in Reactome together with the Reactome Pathway widget are displayed (human complexes only) (Figure 8).
