GOMFOFFSPRING {GO} | R Documentation |
This data set describes associations between GO molecular function (MF) terms and their ancestor MF terms, based on the directed acyclic graph (DAG) defined by the Gene Ontology Consortium. The format is an R environment mapping the GO MF terms to all ancestor terms, where an ancestor term is a more specific GO term that is preceded by the given GO term in the DAG (in other words, the children and all their children, etc.).
Each GO MF term is mapped to a vector of offspring GO MF terms.
Molecular function is defined as the tasks performed by individual gene products; examples are transcription factor and DNA helicase as defined by Gene Ontology Consortium.
Mappings were based on data provided by:
