The Complex Portal is a manually curated, encyclopaedic resource of macromolecular complexes from a number of key model organisms, entered into the IntAct molecular interaction database. Data includes protein-only complexes as well as protein-small molecule and protein-nucleic acid complexes. All complexes are derived from physical molecular interaction evidences extracted from the literature, and cross-referenced in the entry, or by curator inference from information on orthologues in closely related species. Any complex which currently lacks direct experimental evidence is tagged as such, using controlled vocabulary terms from the Evidence Code Ontology.
The number of complexes available is currently limited, but will be added to over time. If you wish to request the curation of one or more complexes, or to amend or contribute to an existing entry, please contact us on intact-help.
