A H3K27me3 reader complex couples H3K27me3 accumulation to nascent transcription of transposable elements in Paramecium - Genome Biology Background The ability to deposit histone H3K27-trimethyl (me3) marks is essential for transcriptional repression by Polycomb Repressive Complex 2 (PRC2). This is largely attributed to Polycomb repres...

Our latest publication is now out at Genome Biology!

Control of retrotransposon-driven activation of the interferon response by the double-stranded RNA binding protein DGCR8 Abstract. The type I interferon (IFN) response is the main innate immune pathway against viruses in mammals. This pathway must be tightly regulated to prev

I'm so happy to share our latest paper! Now out in @narjournal.bsky.social 🥳

Did you know that transposable elements embedded in mRNAs can form dsRNA and activate innate immunity? 🧬🦠 Have a look! academic.oup.com/nar/article/...

I'm looking for a Swiss department to host me for an SNSF Starting Grant.

I research how gene expression evolves and emerges by combining wet lab + computational work in a variety of model systems (E. coli, Drosophila, yeast). More: timothyfuqua.com

If your department might be a match, let’s chat!

This feeling of panic when university tells you that ordering system will undergo change+you cannot order for 10 days 😰Tried to order primers ahead of time but as new data come in, I feel paralyzed to not react+plan follow-up experiments😆 Even after being PI for 17yrs, my❤️ for science never changed!
