Lab presentation

Our research focuses on the structure-function relationships of proteins and macromolecular complexes directly implicated in pathological processes. In particular, virus particles, viral proteins and protein-complexes involved in RNA replication as well as other large macromolecular assemblies. The information obtained would be instrumental not only for improving the knowledge about the functioning of these biological systems but also in the development of novel therapeutic strategies. We use a number of molecular and structural biology techniques. In particular, X-ray crystallography and combinations of X-ray crystallography and Cryo-electron microscopy.

  • Structural and functional studies of viral RNA-dependent RNA polymerases and replication complexes

Most emerging and re-emerging human and animal viral diseases are associated with RNA viruses. One way to limit the impact of these pathogens is to prevent their replication and a thorough understanding of their replication and transcription machineries is therefore essential. Despite this group of viruses use different strategies for genome replication and transcription all RNA virus families depend on the activity of a virally encoded RNA-dependent RNA polymerase (RdRP). The structural information obtained for different RdRP and RdRP-RNA complexes contributed decisively to our knowledge about the functioning these enzymes. Despite the many clues provided by these structures there are still several gaps in our knowledge about the regulation of the RdRP activity and fidelity in different virus families.

We are combining structural data and functional studies to elucidate how RdRPs interact with RNA promotors, other viral proteins and cellular factors, to regulate replication and transcription activities in diferent viruses, including picornaviruses, flaviviruses, coronaviruses and filoviruses. This information will contribute decisively to our knowledge about the mechanisms of action of these enzymes, paving the way for the development of new therapeutic strategies against these pathogens.

  • Protein-protein interactions in viral replication and pathogenesis

RNA viruses usually associate the RdRPs to other viral or host proteins as scaffold to form the replicative complexes in specific intracellular locations like the membranous compartments or inside capsids. The RdRP self-interactions to form dimers and higher order oligomers also play an important role in viral replication, contributing to the fine tuning of the polymerase activity, ensuring the proper levels of RNA production.

We have previous characterized the structure and quaternary arrangement of the  Methyltransferase-RdRP polypeptide NS5 from Zika virus (ZIKV), showing that this protein is able to form dimers and higher-order oligomers that regulate its enzymatic functions, as well as its association with other viral or host factors during infection. More recently we have shown that the multimeric arrangement of ZIKV-NS5 is required for nuclear exit, localization and interaction with primary cilium base proteins, and for promoting ciliopathy and premature neurogenesis. We have also showed that ZIKV-NS5 interacted with and depleted a number of cilia/the centrosome proteins (including, Rootletin, BART1, CEP164) and we aim to structurally and functionally characterize these interactions as new potential targets for therapeutic intervention.

  • Structure and dynamics of viral capsids

We have previously characterized the early steps of human rhinovirus infection, including receptor binding by solving the first high resolution X-ray structures of a human minor group rhinovirus (RV1A) bound to its cellular receptor protein. We have also determined the structural rearrangements occurring in the RV1A capsid trapped in the process of RNA uncoating. We are currently studying the structural dynamics of other RV capsids,  including the effect of a number of capsid binders as antiviral candidates, preventing RNA uncoating.

  • Structural dynamics of the vault shell

Vaults are ubiquitous ribonucleoprotein particles involved in a diversity of cellular processes, with promising applications as nanodevices for delivery of multiple cargos. The vault shell is assembled by the symmetrical association of multiple copies of the major vault protein that, initially, generates half vaults. The pairwise, anti-parallel association of two half vaults produces the whole particle. Using a combination of biophysical and  structural techniques with the production of recombinant mutant vaults, we aim to decipher the principles of vault dynamics and opening.
