GO enrichment analysis tool

GO enrichment analysis tool performs Gene Ontology (GO) term enrichment analysis to identify statistically significant over-representation of GO terms in sets of genes or proteins, elucidating associated biological processes, molecular functions, and cellular components.

Key Features:

• GO enrichment: Identifies statistically significant over-representations of GO terms within input gene or protein sets.
• Controlled vocabulary: Leverages the Gene Ontology Consortium controlled vocabulary and resources (http://www.geneontology.org).
• Ontology coverage: Operates across the three GO ontologies: biological process, molecular function, and cellular component.
• AmiGO 2 integration: Uses AmiGO 2 for access to GO terms, annotations to gene products, and associated metadata across multiple species.
• Ontology expansions: Incorporates GO Consortium expansions including cilia-related terms, cell-cycle terms, and multicellular organism process terms.
• Template-based term generation: Supports the Gene Ontology Consortium approach of generating ontology terms based on logical rules using templates to facilitate term creation and annotation.
• Taxonomic scope: Applies GO annotations consistently across eukaryotic species.

Scientific Applications:

• Phenotype and condition interpretation: Elucidates biological processes, molecular functions, and cellular components potentially involved in specific phenotypes or experimental conditions.
• Genomics and proteomics research: Supports analysis and interpretation of genomics and proteomics datasets across diverse eukaryotic organisms.
• Gene product annotation: Facilitates precise and efficient annotation of gene products using template-supported ontology terms.

Methodology:

Performs statistical assessment of GO term over-representation using the Gene Ontology Consortium controlled vocabulary (http://www.geneontology.org) and annotations accessible via AmiGO 2, and incorporates ontology term expansions and template-based logical-rule term generation.
