mitotic cell division support — The mitotic septin complex is a heterooligomeric septin complex that acts during mitotic cell division.
- GO:0032151 GO:0032151 defines the complex by its action during mitotic cell division.

Septin proteins form a heterooligomeric septin complex that acts during mitotic cell division.

INTERPRETATION (RESOLVED): Keep the mitotic septin complex distinct from the parent septin complex, the meiotic septin complex, and higher-order septin rings. GO:0032151 denotes the heterooligomeric septin complex that acts during mitotic cell division. GO:0031105 is the broader septin-complex parent, GO:0032152 denotes the meiotic counterpart, and GO:0005940 denotes a higher-order septin ring rather than the oligomeric complex.
CURATION_TODO (OPEN): Resolve exact source-neutral family groundings and species boundaries for mitotic septin-complex septin proteins. The initial mitotic septin complex record uses a reviewed-label-only septin protein cohort rather than guessing a family CURIE or importing species-specific paralogs into the generic GO:0032151 record.

GO:0032151 Gene Ontology cellular-component term for the mitotic septin complex.
GO:0031105 OLS reports GO:0031105 septin complex as the direct GO:0032151 parent.
