GOCCCHILDREN {GO} | R Documentation

## Annotation of GO Identifiers to their Cellular Component Children

### Description

This data set describes associations between GO molecular function (CC) terms and their direct children CC terms, based on the directed acyclic graph (DAG) defined by the Gene Ontology Consortium. The format is an R environment mapping the GO CC terms to all direct children terms, where a direct child term is a more specific GO term that is immediately preceded by the given GO term in the DAG.

### Details

Each GO CC term is mapped to a vector of children GO CC terms.

Cellular component is defined as the subcellular structures, locations, and macromolecular complexes; examples include nucleus, telomere, and origin recognition complex as defined by Gene Ontology Consortium.

Mappings were based on data provided:
