Mitotic Metaphase and Anaphase
R-MMU-2555396 in Reactome release 97: under M Phase, with 211 genes placed in it by the mapping files and 2 child pathways in the hierarchy.
The same number in the other species
Reactome writes the mouse and rat events it infers from a human pathway under the human number with the species token. A door opens only where that species' own list in this release holds the id: R-HSA-2555396 (human), R-RNO-2555396 (rat). Whether the event was inferred from this one is what the record says.
01The record
Reactome's own record of this pathway
What this tells you
The pathway list, the hierarchy and the genes on this page are read from the files Reactome publishes for Reactome release 97, built into this site on 2026-09-09: the pathway list, the hierarchy relationship file and the two gene mapping files. The record card is the one live read, Reactome's own record of this pathway.
Reactome's download page describes the mapping files: Mapping files link the source database identifier to the lowest level pathway diagram or subset of the pathway, all levels of the pathway hierarchy or database identifier to all reactions.
[R13] The gene list here is the all-levels mapping of NCBI Gene ids, filled from the all-levels mapping of Ensembl ids where the NCBI file has no row for a gene; each row names which file it came from by the shape of its source id. Each row carries the evidence codes the file writes for it, as written and unranked, and both where the file writes both; no page of Reactome's documentation the survey read defines the codes, so this page does not expand them. A gene id the identity files do not name is kept as the source's own id with no door rather than turned into a symbol.
Every mouse pathway in Reactome is inferred from the curated human one: We use the set of manually curated human reactions to electronically infer reactions in fourteen evolutionarily divergent eukaryotic species for which high-quality whole-genome sequence data are available, and hence a comprehensive and high-quality set of protein predictions exists.
[R11] Reactome's own sentence about what that produces is printed beside the record: The electronically inferred reactions presented in Reactome are thus not data, but hypotheses useful to direct the design of confirmatory experiments.
[R11]
On citing what a search finds, Reactome says: It should be remembered that while we strive to contain the most current and accurate data, Reactome should not be used in citations where other primary sources of information are available.
[R12] The record card prints the literature Reactome attaches to a curated pathway for that reason.

A gene on this list is one Reactome places in this pathway in this release, and that is all the row says: it does not say the gene is expressed in a tissue or associated with a disease, which are the other two explorers' questions, read from other sources. Reactome's papers of record are [R01] [R02].

Evidence codes on this page: IEA, as the mapping file writes them; a row carrying two was written twice by the file, once under each. The mapping file id says which file placed the gene: an NCBI Gene id from NCBI2Reactome_All_Levels.txt, an Ensembl gene id from Ensembl2Reactome_All_Levels.txt. The two files can disagree about a code, so a row's codes are the one file's view. Measured by this site's build over this release on 2026-09-09: the two files disagree on none of the 87,729 mouse pairs both place.

03The hierarchy
Parents and children in this release's hierarchy
Parents
Reactome's hierarchy is a graph rather than a tree: a pathway can sit under more than one parent, and the gene counts are each pathway's own placements at every level under it, so a parent's count is not the sum of its children's.
