The Gene Ontology Resource

The mission of the GO Consortium is to develop a comprehensive, computational model of biological systems, ranging from the molecular to the organism level, across the multiplicity of species in the tree of life.

The Gene Ontology (GO) knowledgebase is the world’s largest source of information on the functions of genes. This knowledge is both human-readable and machine-readable, and is a foundation for computational analysis of large-scale molecular biology and genetics experiments in biomedical research.

The network of biological classes describing the current best representation of the “universe” of biology: the molecular functions, cellular locations, and processes gene products may carry out.


Statements, based on specific, traceable scientific evidence, asserting that a specific gene product is a real exemplar of a particular GO class.


GO Causal Activity Model (GO-CAM) provides a structured framework to link standard GO annotations into a more complete model of a biological system.

Tools & Guides

Tools to curate, browse, search, visualize and download both the ontology and annotations. Includes bioinformatic guides (Notebooks) and simple API access to integrate the GO into your research.
