The Genome Portal includes a tool for browsing through theGene Ontology (GO) and finding genes related to GO terms. GO arranges biological terms under three organizing principles, or ontologies. Each of these is the top level of a deep hierarchical structure of terms. The structures are technically not true hierarchies (they are directed acyclic graphs) in that they allow a child to have more than one parent. Specific gene products are assigned to the terms at various levels in the ontologies.
Aspect | Definition | Examples |
---|---|---|
Molecular Function |
the tasks performed by individual gene products |
carbohydrate binding, ATPase activity |
Biological Process |
broad biological goals that are accomplished by ordered assemblies of molecular functions |
Mitosis, purine metabolism |
Cellular Component |
subcellular structures, locations, and macromolecular complexes |
nucleus, telomere, origin recognition complex |
Using the GO browser, you can:
With the GO browser you can analyze individual or multiple gene model sets by selecting one or more from the menu (see below).
To search an individual gene model set in GO, click to select an item in theSelect Model Set(s) to View menu and click theapply button. The page will refresh to display your selection.
Or, to search multiple gene model sets, hold downCtrl key (on the PC) orCmd key (on the Mac) and click the model sets you wish to view (see below), then click the apply button. The page will refresh to display your selection.
