Ubiquitination is a post translationnal modification where an ubiquitin is attached to a protein. This modification has several consequences, it can lead to the degradation of the protein via the proteasome, it can change the protein localization or it can alter the interaction of the protein with other factors, this is why this modification plays an important role in the control of many cellular processes.

This Sandbox is Reserved from 15/11/2014, through 15/05/2015 for use in the course "Biomolecule" taught by Bruno Kieffer at the Strasbourg University. This reservation includes Sandbox Reserved 951 through Sandbox Reserved 975.
To get started:
  • Click the edit this page tab at the top. Save the page after each step, then edit it again.
  • Click the 3D button (when editing, above the wikitext box) to insert Jmol.
  • show the Scene authoring tools, create a molecular scene, and save it. Copy the green link into the page.
  • Add a description of your scene. Use the buttons above the wikitext box for bold, italics, links, headlines, etc.
