GO Term Name(GO Accession Number)Term TypeDefinition
nucleolus(GO:0005730)cellular_componentA small, dense body one or more of which are present in the nucleus of eukaryotic cells. It is rich in RNA and protein, is not bounded by a limiting membrane, and is not seen during mitosis. Its prime function is the transcription of the nucleolar DNA into 45S ribosomal-precursor RNA, the processing of this RNA into 5.8S, 18S, and 28S components of ribosomal RNA, and the association of these components with 5S RNA and proteins synthesized outside the nucleolus. This association results in the formation of ribonucleoprotein precursors; these pass into the cytoplasm and mature into the 40S and 60S subunits of the ribosome.

 

Click on the GO term name to get the PDB entries for which a UniProt entry annotated with this GO term is available. This covers the query level and all lower hierarchical levels.

Click on the GO accession number to get a tree view of the GO hierarchy without information on PDB entries. In this case your query level and all levels of higher hierarchy up to the root level Gene_Ontology (GO:0003673) are displayed.

If you enter the GO tree somewhere and if you want to get a view of the whole tree first click on the GO name. This yields the low-hierarchy part. Then click on the GO accession number of the lowest hierarchical level. This gives a view of the complete tree. Note, that certain GO terms belong to more than one path.
