Thrilled to share our lab’s first paper out now in @cellcellpress. We identify how a conserved family of Shigella virulence factors inhibits interferon by blocking calcium signalling, promoting virulence cell.com/cell/fulltext/S0092…

Our new paper on KHNYN antiviral activity is available as a preprint. This was another excellent collaboration with @stuartjdneil and Ian Taylor's lab. Great work by @MariaJoseLista2 and all of the team. 1/7 biorxiv.org/content/10.1101/…

Regulation of KHNYN antiviral activity by the extended di-KH domain and nucleo-cytoplasmic traffi...

The zinc finger antiviral protein (ZAP) restricts a broad range of viruses by binding CpG dinucleotides in viral RNA to target it for degradation and inhibit its translation. KHNYN was recently...

We hypothesized that KHNYN co-evolved with ZAP and analyzed the nuclear export signal sequence in a variety of species. In bony fish, which do not have ZAP orthologs, KHNYN does not contain two of the five residues required for the nuclear export signal. 6/7

When ZAP emerged in tetrapods, KHNYN acquired the final two residues of the nuclear export signal. Therefore, we speculate that KHNYN co-evolved with ZAP to allow their interaction in the cytoplasm to restrict viral replication. 7/7

I am grateful to @The_MRC for suporting @stuartjdneil and my lab's research for 3 more years. Also thank you to Irati, Helin, @MattiaFicarelli, @DorotaKmiec, @MariaJoseLista2, Clement, Harry and Rui for their great work, without them there would be no grant!

Thank you to all of the authors for their great work on our paper showing that, despite lentiviral vectors containing a much higher CpG abundance than HIV-1, the CpGs do not appear to sensitise the core lentiviral vector platform to restriction by ZAP. cell.com/molecular-therapy-f…

This supports our idea that high CpG dinucleotide abundance is not sufficient for ZAP to target an RNA. One of our goals is to figure out the design principles for ZAP-response elements to either enrich or supress them in specific RNAs, but we still don't know the rules.

zippity-ZAP⚡️! Our new paper is out @PLOSBiology! I might be biased, but so is the dinucleotide composition of the mammalian interferome 😁, thanks in part to ZAP! journals.plos.org/plosbiolog… Congrats fellow co-first authors @VirusMuser & @NardusMollentze & members of @WilsonLabCVR!

The antiviral state has shaped the CpG composition of the vertebrate interferome to avoid self-ta...

Our cells are poised to combat viral infection through antiviral effectors. This study proposes that as well as targeting viral RNAs, antiviral effectors sometimes target host mRNAs too; over...

We hypothesise that ZAP must associate with cytoplasmic membranes to assemble a complex with cofactors for optimal antiviral activity against viruses with diverse replication sites and strategies, including CpG-enriched HIV-1 and SARS-CoV-2.

1/2 Our review article about genome composition biases in RNA viruses is now online: onlinelibrary.wiley.com/doi/…. TL:DR (it is long): 1. Composition biases occur at mono- and di- nucleotide level and beyond, at amino acid level and codon pairs.

More than 11 years after getting a Marie Curie Intra European Fellowship for this project (and >6 years since generating the last data with Hélène Bauby!), the very last paper from my postdoc is now online @mbiojournal! journals.asm.org/eprint/DWM7…
