Annotation Statistics. Reactome comprises 12,608 human reactions organized into 2,282 pathways involving 11,040 proteins and modified forms of proteins encoded by 10,860 different human genes, 12,335 complexes, 1,856 small molecules, and 222 drugs. These annotations are supported by 30.398 literature references. We have projected these reactions onto 83,183 orthologous proteins, creating 18,679 orthologous pathways in 15 non-human species. Version 70 has annotations for 1,762 protein variants (mutated proteins) and their post-translationally modified forms, derived from 308 proteins. These have been used to annotate 536 complexes and 970 disease-specific reactions organized into 484 pathways and subpathways, and tagged with 387 Disease Ontology terms.

Tools and Data. Our services and software tools are designed for biologists, bioinformaticians, and software developers. Pathway data is available to view in our Pathway Browser, to analyze your own dataset, to download, and to access programmatically through our Content and Analysis Services. The ReactomeFIViz app for Cytoscape provides tools to find pathways and network patterns related to cancer and other types of diseases.

Documentation and Training. Visit our online User Guide to access documentation supporting pathway analysis of experimental data. The Developer's Zone provides detailed documentation regarding our software, tools, and web services. Training and learning materials can be found here.
