Reactome: Quick tour

Life at the molecular level is an intricate network of protein interactions and biochemical reactions. A pathway is a small part of this network – a series of connected events, typically characterised by the product or biological outcome. Researchers have defined many biological pathways. These pathways can be accessed via the scientific literature, textbooks, or electronic databases, but the information is of variable quality and is largely unavailable for computational re-use. Reactome provides access to a curated, quality-assured slice of this information, available as diagrams and descriptions on the Reactome website and as downloadable pathways in standard formats such as BioPAX [3] and SBML.
