The Complex Portal is a comprehensive, manually curated resource of macromolecular complexes from key model organisms. It serves as an authoritative aggregator that combines expert manual curation with high-confidence machine-learning predictions to provide detailed annotations for protein complexes that have been experimentally characterized.
The Complex Portal defines complexes as assemblies of two or more proteins and/or nucleic acids that are stable enough to be reconstituted in vitro and have demonstrated specific molecular functions. The resource covers multiple organisms:
Each complex entry provides:
In addition to manually curated complexes, the portal includes:
Data is systematically organized by:
The Complex Portal integrates with and contributes to:
The Complex Portal is freely available under CC BY 4.0 license. Users should cite both the database and specific datasets used. The resource serves as a Global Core Biodata Resource and is part of the ELIXIR infrastructure for biological data management.
