When cellular proteins meet SARS-CoV-2 RNA: a story of protein-RNA interactions

I our recent work we comprehensively and systematically identify the complement of cellular RNA-binding proteins that are involved in SARS-CoV-2 infection. We discover that the cellular RNA-binding proteome (RBPome) is pervasively remodelled upon SARS-CoV-2 infection, affecting a broad range of RNA metabolism and antiviral pathways. We also apply a new method to uncover the composition of SARS-CoV-2 RNPs, revealing a dozens of cellular RBPs and seven viral proteins. Our study reveals a new universe of host-virus interactions awaiting to be characterised and with great potential for novel therapies againt COVID-19.

This work is a synergistic collaboration between the Castello, Mohammed, Bartenschlager, Martinez and Lilley labs. See full publication in BioRxiv below:

Discovering the RNA-Binding Proteome of Plant Leaves with an Improved RNA Interactome Capture Method

RBPs are key key drivers of gene expression by controlling RNA fate. However, our knowledge about RBPs in plants is very limited. I our recent work, we report an improved RNA interactome capture approach to discover RNA-binding proteins (RBPs) in plant leaves . Using this ‘plant-adapted RNA interactome capture’ (ptRIC) we have identified hundreds novel RBPs, including many enzymes and proteins from the photosynthetic apparatus. ptRIC did not only allowed the generation of the deepest ‘RBPome’ of plant tissue to date, but also opens the possibility to study how the RBPome remodels in response to environmental, physiological and pathological cues.

This work is an interdisciplinary collaborative effort between the Castello lab (Department of Biochemistry) and Preston lab (Department of Plant Sciences) at the University of Oxford. Find out more about this work here:
