Reactome ("http://www.reactome.org":http://www.reactome.org) is an expert-authored, peer-reviewed knowledgebase of human reactions and pathways that functions as a data mining resource and electronic textbook. Its current release includes 2921 human proteins, 2871 reactions and 4167 literature citations. This curated dataset is integrated with a functional interaction network assembled computationally from non-curated sources of information including protein-protein interactions, gene co-expression, and gene ontology annotations, providing access. A new entity-level pathway viewer and improved search and data mining tools facilitate searching and visualizing pathway data and the analysis of user-supplied high-throughput data... |
