About the resource

Experimentally identified sites across species

Protein O-GlcNAcylation has been documented in metazoans—including animals, insects, and plants—as well as some bacteria, fungi, and viruses. It occurs on proteins in the nucleus, cytosol, and mitochondria and functions in a species-, tissue-/cell-, protein-, and site-specific manner.

O-GlcNAcAtlas retains the species, sample, protein, peptide, site, publication, and quantitative context needed to interpret this experimental evidence.
