About Reactome
Reactome is a free, open-source, curated and peer reviewed pathway database. Our goal is to provide intuitive bioinformatics tools for the visualization, interpretation and analysis of pathway knowledge to support basic research, genome analysis, modeling, systems biology and education. The current version (v49) of Reactome was released on July 15, 2014.

The development of Reactome is supported by a grant from the US National Institutes of Health (P41 HG003751), Ontario Research Fund, and the European Molecular Biology Laboratory.
