Reactome incorporate manually curated human reactions and PANTHER's protein homology data to Computationally infer events in other eukaryotic species.

rba_reactome_orthology(event_ids, species_dbid, ...)



Human Reactome event ID(s) to retrieve their orthologous events.


Reactome database ID (DbId) of the target species. (e.g Mus musculus is 48892). See rba_reactome_species or Reactome Data Schema: Entries: Species.


rbioapi option(s). See rba_options's arguments manual for more information on available options.


List containing found Orthologous event(s) in your supplied species and their pertinent information.


In version 73 (11 June 2020), using an orthology-based approach, Homo sapiens events was projected to 18,654 orthologous pathways (with 81,835 orthologous proteins) in 15 non-human species.
See Reactome Computationally Inferred Events for more information.
