Services and Repositories

  • Content Service: Our Content Service provides outside users with direct access to pathway data in Reactome via an API. 
  • Analysis Service: The Reactome Pathway Analysis Tools offer direct access to pathway analysis via an API, and are also available for integration into third party websites.
  • Zenodo Repository: The Zenodo download directory is created for every Reactome (reactome.org) release quarterly, starting from version 89 (06/2024), containing download files. 
  • GitHub Repository

Mapping Files

Identifier mapping files

Mapping files link the source database identifier to the lowest level pathway diagram or subset of the pathway, all levels of the pathway hierarchy or database identifier to all reactions.   


Lowest level pathway diagram / Subset of the pathway

All levels of the pathway hierarchy.     

Database identifier to all reactions.         

Physical Entity (PE) Identifier mapping files 

Mapping files link the source database identifier to the lowest level pathway diagram or subset of the pathway.     

Lowest level pathway diagram / Subset of the pathway

All levels of the pathway hierarchy.     

Database identifier to all reactions           

Other Mappings

Icons

The icon mapping files link the source database identifier to elements of the icon library. This folder contains a number of different mapping files to reflect the different source databases.

Protein-Protein Interaction Files 

Protein-Protein Interactions derived from Reactome pathways

Interactions are inferred between all protein components of a complex. To limit the creation of false-positive inferences, only complexes with four or fewer protein components are considered. More information

PSI-MITAB format interaction files

TAB-delimited format interaction files

Functional interactions (FIs) derived from Reactome, and other pathway and interaction databases

For details about FIs, please see Wu G, Feng X, Stein L. To use these FI networks, please try our ReactomeFIViz Cytoscape app.

Version 2022 (Constructed with a new random forest classifier. For more information, refer to Illuminating Dark Proteins using Reactome Pathways)

Version 2021

Version 2020 (See note below)

Version 2019

Version 2018

Note: The number of predicted FIs has dropped about 50% from Version 2019 to Version 2020 most likely because we excluded BioGrid protein-protein interactions collected in iRefIndex. We found an abnormal high odds ratio for mapped worm protein-protein interaction feature from BioGrid, which was much higher than human PPIs (120 vs. 80) and other no-human PPI features.

Curation Team Software

The Curator tool is meant for use by curators to annotate biological pathways based on the Reactome schema. Please note that this tool will only work with a database using our internal database format; the database available from this web page will not work with them.
