  3. GO search and display tool Leaf node GO term (GO:0006366): mRNA transcription from RNA polymerase II promoter

  4. Human p53 – GO annotation (UniProtKB:P04637) GO:0006289:nucleotide-excision repair [PMID:7663514; evidence:IMP] http://pir.georgetown.edu/cgi-bin/ipcEntry?id=P04637

  5. ~46 Human, mouse, plant, worm, yeast … GO annotation of gene products • Science basis of the GO: trained experts use the experimental observations from literature to associate GO terms with gene products (to annotate the entities represented in the gene/protein databases) • Enabling data integration across databases and making them available to semantic search http://www.geneontology.org/GO.current.annotations.shtml
