Selectively manipulating protein modifications

terium Archaeoglobus fulgidus.

"We therefore assume that the reversal of the modification takes place in a similar way in different species," explains Michael Hottiger.

Biomedically relevant: inactivation of the modified enzyme GSK3β

The researchers also prove that ADP-ribosylhydrolases can remove the ADP-ribose of the intensively studied enzyme GSK3β, which regulates the synthesis of storage substances and is important in the progression of various diseases. ADP-ribosylation deactivates GSK3β, which can be reversed again by the newly identified enzyme. "Our discovery enables ADP-ribose modification to be manipulated and tested selectively, and new treatment methods developed for diseases such as inflammations or cancer," concludes Michael Hottiger.
