Is it a virus, or a retrotransposon? Amazing story how an endogenous retrotransposon uses a small, FAST-like protein to cause soma-to-oocyte transfer in Drosophila.

Kudos to @mayavoichek.bsky.social, Kirsten Senti, @juliusbrennecke.bsky.social plus the entire team for this exciting discovery!
Super excited to share my postdoctoral work at @imbavienna.bsky.social @viennabiocenter.bsky.social -
We discovered that some retrotransposons, or "jumping genes" 🧬, are able to spread from cell to cell via a new viral infectivity route.

The HuSH complex silences retrotransposable elements. We identify HuSH2, centered on TASOR2, targeting KRAB-ZNFs and interferon genes, balancing retrotransposon silencing and immune regulation. www.nature.com/articles/s41...

This new mechanism of retrotransposon invasion will be a landmark finding in retrotransposon biology

Very creative and thorough genetic and mechanistic dissection.

Excited to see what studies of more transposon-encoded peptides and proteins like sORF2 will uncover!

biology is just really cool
1/ Transposable elements are often called "jumping genes" because they mobilize within genomes. 🧬
But did you know they can also jump 𝘣𝘦𝘵𝘸𝘦𝘦𝘯 cells? 🤯
Our new study reveals how retrotransposons invade the germline directly from somatic cells.

Differential methylation of a retrotransposon upstream of a MYB gene causes variegation of lettuce leaves, which is abolished by the presence of an (AT)5 repeat in the promoter
Variegation is a common feature in plants and provides a significant opportunity for understanding genetic, developmental, and physiological processes. We identified a retrotransposon insertion withi...
