Current release and historical evidence

O-GlcNAcAtlas statistics

Live Atlas 5.0 metrics are derived from tracked release data. Fixed publication figures are presented separately as historical snapshots.

Current live release

O-GlcNAcAtlas 5.0 metrics

These values are derived from the tracked dataset-I and dataset-II release files rather than copied from publication figures.

A distinct protein is a trimmed, nonblank accession. A distinct site is a unique complete accession, position-in-protein, and residue tuple; incomplete identifiers remain in the curated record total but are not counted as unique sites.

Fixed publication figures

Historical statistics, 1984–December 31, 2024

These fixed figures accompany prior publications and are historical snapshots, not current live release metrics.
