Sugar Tags On Nuclear Proteins Have An Important Developmental Function

Proteins are the executive agents that carry out all processes in a cell. Their activity is controlled and modified with the help of small chemical tags that can be dynamically added to and removed from the protein. 25 years after its first discovery, researchers at the European Molecular Biology Laboratory (EMBL) in Heidelberg have now gained insight into the role of one of these tags, a small sugar residue, that is found on many different proteins across species.
