Project description
A protein-RNA complex key to influenza transcription
Influenza viruses are RNA-based viruses that pose a major threat to human health through annual epidemics and occasional pandemics. Understanding the biology of influenza viruses is central for the design of antiviral drugs and vaccines. The EU-funded Influenza RNP project will investigate the ribonucleoprotein complexes (RNPs) involved in the transcription of viral genomic RNA into mRNA. Researchers aim to delineate the dynamic changes in structure of the RNPs as transcription proceeds. Results will provide fundamental molecular and biochemical information on the mechanisms of replication of influenza viruses, opening new avenues for anti-influenza pharmaceutical research. Additionally, the methods developed may be applied to study the essential ribonucleoprotein complexes of other pathogenic RNA viruses.
Objective
Influenza is a major public health burden, with seasonal outbreaks contributing significantly to mortality worldwide, and the emergence of pandemic strains remaining an ever-present threat. Influenza drug and vaccine conception efforts are aided by a thorough understanding of its molecular biology.
A key aspect of the influenza lifecycle is the production of capped and poly-adenylated messenger RNA by the heterotrimeric influenza polymerase (FluPol). Ground-breaking work performed by the Cusack lab, has described with residue-resolution detail, the FluPol structures that form during transcription of short, non-nucleoprotein (NP) bound viral RNAs (vRNAs). However, influenza transcription in vivo occurs within the ribonucleoprotein (RNP) particle and does not utilise naked genome segments. The viral RNP (vRNP) is a super-helical complex composed FluPol bound at the conserved 3′ and 5′ ends of a vRNA, which is coated with NP. The current low-resolution structures provide little information about the molecular details of vRNP function, particularly, how NPs interact with FluPol and the vRNA template.
Via an inter-disciplinary approach, I will utilise cryo-electron microscopy methods, transcription assays and single-molecule fluorescence, to obtain the first high resolution structure of a dynamic influenza vRNP, with a particular focus on the spatial organisation of NPs relative to FluPol. In addition to this work facilitating future influenza drug research, it will provide a basis to investigate the vRNP during other lifecycle stages and act as proof-of-principle for study of other viral protein-RNA complexes, such as those from corona-, arena- and bunyaviruses.
Work will be performed in the groups of Stephen Cusack and Olivier Duss based at EMBL Grenoble and Heidelberg, respectively. Here, I will have access to world-leading facilities and training opportunities, supporting my growth as an independent researcher and an expert in RNA virus structural biology.
