GO Term Name(GO Accession Number)Term TypeDefinition
hormone activity(GO:0005179)molecular_functionThe action characteristic of a hormone, any substance formed in very small amounts in one specialized organ or group of cells and carried (sometimes in the bloodstream) to another organ or group of cells in the same organism, upon which it has a specific regulatory action. The term was originally applied to agents with a stimulatory physiological action in vertebrate animals (as opposed to a chalone, which has a depressant action). Usage is now extended to regulatory compounds in lower animals and plants, and to synthetic substances having comparable effects; all bind receptors and trigger some biological process.


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.
