Reactome: biological pathways and pathway enrichment

Reactome, the open, expert-curated knowledgebase of biological pathways and reactions (OICR, EMBL-EBI, NYU Langone and OHSU), through its Content Service and Analysis Service. Finds the pathways a gene, protein or chemical takes part in (gene symbol, UniProt, Ensembl, NCBI Gene or ChEBI ID), or pathways by name or topic; reads one pathway's curated summary, literature with PubMed IDs, GO process, disease terms, orthologs and its place in the pathway hierarchy; lists a pathway's participating proteins (UniProt), genes, RNAs and chemicals (ChEBI); and runs over-representation analysis of a gene list (hypergeometric test, FDR) with the genes found per pathway. Human pathways are curated and inferred for 15 model organisms; about 2,700 human pathways and 16,000 reactions. Reactome data is CC0 1.0; every answer carries the release and Reactome's citation.

Reactome: biological pathways and pathway enrichment
TRY ASKING
1Request
string[]Required

Genes, proteins or chemicals of one species: gene symbols (`TP53`, human only), UniProt accessions (`P04637`), Ensembl IDs, NCBI Gene IDs or ChEBI IDs, one per item. Repeats are dropped. Separate values with commas.

boolean

Include Reactome's disease pathways in the analysis. Default true.

number

Most pathways to return.

boolean

Keep only Reactome's lowest-level pathways (those drawn in a pathway diagram), dropping broader groupings such as Signal Transduction. Default false.
