Gene ontology

Definition

Gene ontology (GO) is a framework used to represent and classify the functions of genes and their products across different species. It provides a standardized vocabulary for describing gene function, allowing for easier comparison of gene functions across diverse biological systems. GO encompasses three main categories: biological process, molecular function, and cellular component, enabling comprehensive analysis of the roles that proteins play in various contexts.

5 Must Know Facts For Your Next Test

1. Gene ontology facilitates data integration by providing a consistent way to annotate proteins with functional information, crucial for comparative proteomics.
2. The GO database is continually updated by contributions from researchers worldwide, ensuring it reflects the latest scientific findings.
3. By using gene ontology terms, researchers can better visualize the relationships between proteins and their functions within different biological contexts.
4. GO annotations can significantly enhance the interpretation of proteomics data by linking identified proteins to their known biological roles.
5. Gene ontology also supports multi-omics integration by allowing researchers to connect protein function with genomic and transcriptomic data.
