Protein complexes with higher disorder are less sensitive to molecular chirality, compared to folded complexes. We now show that the translocation carrier Importin Ξ±3 is highly tolerant of the stereochemistry of nuclear localization signals in both folded proteins and IDPs.

Scientific journals are complaining that they are having a harder time finding reviewers. Yet, I just found out that I set my new personal record by serving as one of EIGHT reviewers for a manuscript. That seems like a lot!

We expanded the chemical space of inhibitors of intrinsically disordered proteins to include silicon compounds. Affinities measured in vitro are not very high, but simulations demonstrate a well-defined binding mechanism. Thus, we have ideas on how to improve these molecules.

Italy's largest research organization (#CNR) has been left without a President – and no one knows why. The previous President's term has expired, yet the process of appointing a new one has not even started. Most of the Board of Directors' terms have also expired, so we are now close to a paralysis.

Citrullination at the N‐terminal region of MDM2 by the PADI4 enzyme PADI4 is one of the human isoforms of a family of enzymes involved in the conversion of arginine to citrulline. MDM2 is an E3 ubiquitin ligase that is critical for degradation of the tumor suppressor...

Citrullination is a post-translational modification that is critical for many physiological processes. We combined experiments and simulations on disordered peptides to identify the citrullination sites of MDM2, an IDP that acts as a key regulator of the tumor suppressor p53.

Development of an efficient NUPR1 inhibitor with anticancer activity - Scientific Reports Scientific Reports - Development of an efficient NUPR1 inhibitor with anticancer activity

Drug design against a 100% disordered protein is challenging. Our latest effort combined high-throughput screening with remodeling of the lead compound. The resulting drug candidate reduced tumor growth in a xenograft mouse model of human pancreatic cancer.
