What is O-GlcNAcAtlas?
O-GlcNAcAtlas is a comprehensive, curated database of experimentally identified O-GlcNAc sites and proteins reported over the past several decades, beginning with the modification’s discovery in the early 1980s.

How do I use O-GlcNAcAtlas?
- Obtain a protein name, gene symbol, accession, or peptide sequence of interest.
- Choose the matching search field. Specific identifiers such as a gene symbol or accession generally produce more focused results; for example, use
MAPTorP10636for human tau. - Filter the result table to narrow records by details such as species or site.
- Copy the visible rows or download the complete filtered result as CSV.
