The 2025_04 release of UniProtKB is now available. Approximately 82M UniProt IDs were removed; as a result, the UniProt pages providing functional annotation for these IDs are no longer active.
This "Metadata Viewer" provides access to the node attribute metadata for all UniProt IDs in the 2025_03 release that the tools continue to use during the UniProtKB reorganization.
Enter one or more UniProt IDs, separated by new lines.
