Young KRAB-zinc finger gene clusters are highly dynamic incubators of ERV-driven genetic heterogeneity in mice - Nature Communications
KRAB-zinc finger proteins repress retrotransposons and rapidly evolve in mammals. Here, the authors show that ERV insertions drive the emergence and diversification of new KZFP genes in mice, revealin...

So excited to see this out on bioRxiv! Huge thanks to @kaessmannlab.bsky.social and the amazing cerebellum team (@marisepp.bsky.social and @ioansarr.bsky.social) for all the support and insightful discussions that made this work possible!!
Did transposable elements shape brain evolution — and if so, which ones, and in which cell states and lineages? Led by @tyamadat.bsky.social, we explored this question in cerebellum development using sequence-based deep learning models!
