Post-translational modifications of proteins can influence for example their localisation, stability and interactions. They are important throughout life, from early development to being deregulated in disease. Some are well studied, like phosphorylation or ubiquitination, others remain more obscure still. We are interested in the modification of proteins with ADP-ribose.

Of long unknown importance, slowly its functions are emerging, such as in innate immunity and metabolism. We are interested in both the enzymes that add ADP-ribose to proteins, the PARPs or ARTDs, and the enzymes that remove it, the macrodomain-containing hydrolases. By determining these enzymes’ function in in vitro and in vivo systems, we intend to further uncover the processes influenced by mono(ADP-ribosyl)ation. This will then enable us to decipher where ADP-ribosylation goes wrong in disease onset and progression.
