Reactome is seeking expert help for the curation of new modules
The Reactome knowledgebase relies on collaborations with research biologists to construct expert consensus views of key biological processes, and to integrate these with other processes already in Reactome. We are seeking new author-collaborators. If you're interested, or would like more information about our data acquisition process, please contact us at editorial@reactome.org.

About Reactome   News and Notes
The Reactome project is a collaboration among Cold Spring Harbor Laboratory, The European Bioinformatics Institute, and The Gene Ontology Consortium to develop a curated resource of core pathways and reactions in human biology. The information in this database is authored by biological researchers with expertise in their fields, maintained by the Reactome editorial staff, and cross-referenced with the sequence databases at NCBI, Ensembl and UniProt, the UCSC Genome Browser , HapMap, KEGG(Gene and Compound ), ChEBI, PubMed and GO. In addition to curated human events, inferred orthologous events in 22 non-human species including mouse, rat, chicken, puffer fish, worm, fly, yeast, two plants and E.coli are also available. A description of Reactome has been published in Genome Biology and Nucleic Acids Research.

Reactome is a free on-line resource, and Reactome software is open-source. However, please take note of our disclaimer.
