The best-characterized inositol pyrophosphates are the diphosphoinositol pentakisphosphate IP7 and the bis-diphosphoinositol tetrakisphosphate IP8. Our ability to produce radiolabeled IP7 with high specific activity has allowed us to detect the direct transfer of the radiolabel beta phosphate from IP7 to proteins. This phosphorylation mechanism defines a yet new kind of protein post-translational modification.
A recent study has shown that inositol pyrophosphates donate the phosphate group to pre-phosphorylated serines, thus generating a pyro-phosphorylated protein. Although we are able to reproducibly transfer phosphate moieties from IP7 to pre-phosphorylated serine of proteins in vitro and have indirect evidence that IP7 can directly mediate phosphorylation in vivo, the molecular mechanisms underlying IP7-dependent protein pyro-phosphorylation in vivo and the physiological consequence of such, are not fully elucidated yet.
The main objective of my laboratory is to identify the physiological functions of inositol pyro-phosphates.
The physiology and pathology of inositide signaling in the nucleus
We are employing several experimental models from yeast Saccharomyces cerevisiae, a simple but powerful genetic model, to mouse knockout to mimic human physiology. We are routinely using several biochemical, molecular biology and cell biology techniques. It has become increasingly clear that inositol pyrophosphates have a very basic signalling function inside all eukaryotic cells. It is likely that the inositol pyro-phosphates have evolved dedicated roles due to their unique biochemistry.
The potential therapeutic potential of such research is supported by the recent identification of the critical role inositol pyrophosphates in the regulation of insulin secretion and oncogenic processes. We have substantially contributed to both studies.

Can be use to identify IP6K inhibitors. Although this technology was just published in May by October the majority of scientists working on inositol pyrophosphate research have adopted this new method. I hosted several students and postdoc from around the world in my lab to directly learn this powerful technology. Open Biol. Many paper are coming out using this methods that have helped to develop new chemical tools, such: Prometabolites of 5-Diphospho-myo-inositol Pentakisphosphate. Angew Chem Int Ed Engl. Collaborator Contribution They have allowed me to study signaling by inositol phosphates in neuronal cell.
