Proteins are involved in virtually every biological process. To function, these chains must fold into the unique three-dimensional structure that is characteristic for each protein. In addition, proteins almost never act in an isolated manner; they interact with other proteins in order to perform essential roles in many important cellular processes. Protein malfunction is often related to disease and thousands disease-related proteins have been identified to date. In many cases, these disorders are the outcome of a failure in their folding process and/or in their binding to one or more protein partners. 

Protein Folding

Folding of Disulfide-Rich Proteins 
We exploit the particular chemistry of disulfide bonds to characterize the folding of disulfide-rich proteins with results that illustrate a high diversity of folding mechanisms. Also, by combining kinetic studies with the structural determination of folding intermediates, we have provided new molecular clues in oxidative folding and clarified some of the major rules that govern it. 

Folding of Cell Signalling Domains
Intracellular signalling networks controls cellular behaviour, and are assembled through the interactions of proteins with one another, and with other molecules. Typically, protein interaction domains are independently folding modules that can be expressed in isolation from their host proteins while retaining their intrinsic ability to bind their physiological partners. After establishing the SH3 domain as a consistent model for the study of protein folding and binding, we plan to expand our activity to other cell signalling domains. Understanding how they fold and bind is of paramount importance since many human disorders result from breakdowns in protein binding and signal transduction.

Protein Misfolding and Aggregation

We are interested in disease-related misfolding and amyloid fibril assembly.

In vitro Models 
We have shown that amyloid formation depends on specific short amino acid stretches, opening a door for the prediction of therapeutically relevant regions in amyloid proteins. These regions are usually protected inside the protein globular structure, suggesting a selection against aggregation during evolution. Using this information, we have developed AGGRESCAN, a software for the prediction of protein aggregation propensity ( Integrating computational and experimental approaches we are studying the relationship between the sequence and the structural properties of the aggregated and toxic states of several amyloid proteins, including prions, IAPP and Aß peptide. 

In vivo Models
We have established bacteria as a simple cellular model to study in vivo protein aggregation, and demonstrated the formation in prokaryotes of oligomers and amyloid structures through selective interactions. This suggest evolutionary conserved strategies to avoid the harmful effects of protein aggregation by sequestering sticky folding intermediates into stable aggregated structures in both eukaryotes and bacteria. We are now using proteomic and genomic approaches to explore the sequential and structural determinants of amyloid formation inside eukaryotic cells using yeast as a model. 

Protein-Protein Interactions

Even though most of the relevant interactions in the cell are weak and in many cases transient, there are only few methods able to detect them in vivo. Using protein engineering we have shown that bimolecular fluorescence complementation can be implemented for the detection and high-throughput screening of weak protein binders and inhibitors of such interactions. Specifically, using this approach we have been able to correlate the antimicrobial activity of natural and designed peptides with their ability to inhibit bacterial chaperones in vivo. This opens an avenue for the design and assay of new and specific antibiotics.
