# Update Existing Protein Existing proteins can be updated using one of many links on each protein page, these are the most notable: * "Edit States/Attributes" button below the Attributes table * "Submit a change" button at the bottom of the page. Either of those will bring you to that protein pages update form: [www.fpbase.org/protein/\`protein\_slug\`/update/](http://www.fpbase.org/protein/`protein_slug`/update/) The form is the same as the [new submission form](/contributing/submit-protein.md), but pre-populated with the existing data. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
