Reactome: A Curated Database of Human Biological Pathways Lincoln Stein Infectious Disease Ontologies CSHL 2007
Reactome • A computable representation of human pathways and reactions. • Uses a “chemical” reaction model to represent causality. • Molecules identified explicitly – including small molecules, proteins, complexes, post-translational modifications, compartments. • Exportable as SBML, BioPax, PDF and MySQL dumps. • Open Source • Authored & curated by experts in the field.
Where the Data Comes From • Recruit bench scientists to write modules. • Authors use a software tool to describe their pathway. • All molecules must be identified explicitly. • All assertions backed up by literature references. • Curators work with authors to ensure consistency and completeness. • Module checked by peer review & software before publication.
Increasing Coverage • Add non-Reactome data sets to create a “corona” of less reliable data around each pathway. • Corona connected to pathway components by probable functional interaction links.
Reactome & Infectious Disease • Via collaboration with Richard Scheuermann, have created an influenza lifecycle module. • 64 reactions, 338 molecules • Modeling issues: • Is the virion a molecular complex? A compartment? A cell? • When is it OK for the proteins of two species to interact? • We’d encourage other groups to do this for more pathogens.
Physiology vs Pathophysiology Reactome databases • Normal physiological pathways • Pathophysiological pathways Non-Reactome databases specialized for infecious disease • Ontology dbs • WIKIs • Pathogen metagenome databases • etc
