Welcome to the Gene Ontology Tools developed within the Bioinformatics Group at the Lewis-Sigler Institute.

The GO Help Page at SGD gives the following description of the Gene Ontology:

"The Gene Ontology (GO) project was established to provide a common language to describe aspects of a gene product's biology. The use of a consistent vocabulary allows genes from different species to be compared based on their GO annotations. The objective of GO is to provide controlled vocabularies for the description of the biological process, molecular function, and cellular component of gene products. These terms are to be used as attributes of gene products by organism databases, facilitating uniform queries across them. The controlled vocabularies of terms are structured to allow annotation of gene products to GO terms at varying levels of detail and to query for gene products that are involved in similar processes, function and components."

For more information on GO, please see the related GO Resources.

• Generic GO Term Finder
  This web tool finds the significant GO terms shared among a list of genes from your organism of choice, helping you discover what these genes may have in common.
  
  Sample view of GO Term Finder results in: HTML table | GO tree view image for sample gene list from Saccharomyces Genome Database (SGD).


• Generic GO Term Mapper
  This web tool maps the granular GO annotations for genes in a list to a set of GO slim terms, allowing you to bin your genes into broad categories.
  
  Sample view of GO Term Mapper results in HTML table for sample gene list from Saccharomyces Genome Database (SGD).
