David Functional Annotation |work| Jun 2026

Here is your guide to getting the most out of DAVID functional annotation in 2024.

Researchers typically input a list of differentially expressed genes to determine which biological pathways are up- or down-regulated in their experiment.

DAVID is not fancy. It doesn't have a shiny AI chatbot. It doesn't do single-cell trajectory inference. david functional annotation

: DAVID excels at cross-referencing hundreds of different gene and protein identifier types, consolidating them into a single, unified "DAVID Gene" concept to ensure no data is lost during analysis. DAVID Functional Annotation Bioinformatics Microarray Analysis (.gov) +9 Expanding Knowledge and Capability Since its debut in 2003, DAVID has undergone massive updates to remain relevant in modern biology. A significant 2021 update expanded its taxonomy coverage from roughly 17,000 to over 55,000 organisms. It now integrates diverse data types beyond standard GO terms, including: PubMed Central (PMC) (.gov) +2 Small molecule and drug interactions from PubChem and DrugBank . Tissue expression information from the Human Protein Atlas . Disease associations from DisGeNET . Conclusion By bridging the gap between raw genomic data and biological interpretation, DAVID remains an essential tool for biologists. Its ability to cluster redundant information and provide statistical validation for biological themes ensures that researchers can confidently move from "what genes changed" to "what biological processes are occurring".

Researchers typically use DAVID after high-throughput experiments, such as microarrays or RNA-Seq, to interpret the functional significance of differentially expressed genes. Key Functional Annotation Capabilities
