Review:
Functional Annotation Databases (e.g., Go, Kegg)
overall review score: 4.5
⭐⭐⭐⭐⭐
score is between 0 and 5
Functional annotation databases, such as Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG), are comprehensive resources that provide structured information about gene functions, biological processes, molecular functions, cellular components, and metabolic pathways. They serve as essential tools in bioinformatics for annotating genes and proteins, facilitating the understanding of biological systems and aiding in functional genomics research.
