The "timeline" option under the views dropdown displays search results in a vertical timeline. To jump to a specific time period, select a year from the right navigation menu or scroll down the page to load subsequent years.
Each structure shown in the profile is ordered by the release date shown, and links to the Structure Summary page for the entry. Structures can be sorted by Newest or Oldest structure.
The first deposited instance of a particular protein or protein complex is displayed larger than future examples of similar molecules that contain the same set of UniProtKB IDs.
To avoid performance issues, search results that return more then 3000 results have their timeline view disabled. A future release will re-enable this feature for all search queries.
What is a unique structure?
Unique structures, denoted by a blue background, are the first structure of a polymer or polymer complex deposited by the researcher. Subsequent structures that contain the same set of UniProtKB cross-reference identifiers, will be displayed with a smaller image to help bring attention to the deposition of structures of new molecules.
