 Project objective

Here I propose to use small molecules to degrade proteins specifically around sites of DNA damage by using the damage itself as a homing signal. The approach will create new ways to study DNA damage, but will also offer translational possibilities in cancer. Cancer cells are often acutely sensitive to DNA damage because they have one or more faulty DNA damage response (DDR) pathways – a feature that makes them highly dependent on their remaining DNA repair systems. We will pioneer two novel and related chemical approaches for selectively killing cancer cells by modulating DDR pathways with bifunctional DNA damaging molecules. We will do this by reprogramming E3 ligases. E3 ligases are modular multi-protein complexes that destabilize cellular proteins by catalysing the formation of polyubiquitin chains on its substrates, which serve as a signal for proteasomal degradation. A recent revolutionary advance in chemical biology is to use small molecules to reprogram the protein degradation specificity of E3 ligases. By degrading proteins instead of inhibiting them, these small molecules achieve levels of functional modulation typically only possible with genetic techniques. We are inspired by this new protein degradation technology, but will take it in a new direction. Chemical damage of DNA recruits E3 ligases as well as critical DDR proteins in preparation for DNA repair. We will invent a new generation of small molecule protein degradation catalysts by repurposing these natural responses to DNA damage. We will accomplish our goal with three aims: Aim 1: Use DNA damage as a homing signal for induced protein degradation Aim 2: Use direct repair of DNA damage by the repair protein MGMT to promote the degradation of other proteins Aim 3: Promote pleiotropic protein degradation by recruiting broadly acting E3 ligases to sites of DNA damage

I propose an ambitious project that will create conceptually novel ways to study the DDR and potentially build new medicines.

Are you the coordinator (or a participant) of this project? Plaese send me more information about the "EXPLODPROTEINS" project.

For instance: the website url (it has not provided by EU-opendata yet), the logo, a more detailed description of the project (in plain text as a rtf file or a word file), some pictures (as picture files, not embedded into any word file), twitter account, linkedin page, etc.

Send me an  email (fabio@fabiodisconzi.com) and I put them in your project's page as son as possible.

Thanks. And then put a link of this page into your project's website.
