Happy to share PhD work of @shamithagovind.bsky.social She unraveled how GTSF1, a protein known from the Piwi field, regulates RdRP in nematodes. Thanks also to @psarkies.bsky.social @sebastianfalk.bsky.social Ralf Sommer, Falk Butter, @migueldvalmeida.bsky.social link.springer.com/article/10.1...

An evolutionarily conserved N-terminal domain of RRF-3 governs GTSF-1 binding in nematodes - EMBO Reports
GTSF1 is an essential activating cofactor for PIWI proteins in many metazoans. In the nematode Caenorhabditis elegans, however, GTSF-1 does not bind PIWI, but is associated with the RNA-dependent RNA ...

For 40 years the 8-nt ‘Kozak Sequence’ was thought to mark sites of translation initiation. In a new study, we revise this model by identifying an ~80-nt sequence—the extended Translation Initiation Sequence (eTIS)— that guides ribosomes to correct start sites. 🧵 www.biorxiv.org/content/10.6...

New paper in Genes & Dev: we dissected how Sox2 — a key pluripotency TF — is regulated by a distal enhancer cluster (SCR) 100 kb away. The results challenge simple models of cohesin-mediated loop extrusion of gene regulation. genesdev.cshlp.org/content/earl... 🧵

How does the piRNA pathway solve the self vs. non-self problem? 🧬 Since piRNAs come from single-stranded RNA, how does the cell choose the right ones? For years, "piRNA clusters" were seen as THE privileged source. But are they really special and earmarked for biogenesis? (1/19)

💥Finally out! Answering a two-centuries old question about a membraneless organelle that forms in #oocytes from insects to humans: the Balbiani body (Bb). Now in @currentbiology.bsky.social : cell.com/current-biol... >
cell.com
The Balbiani body is formed by microtubule-controlled molecular condensation of Buc in early oogenesis
Kar et al. demonstrate that Balbiani body (Bb) formation is achieved via developmental condensation in zebrafish oogenesis, driven by Buc phase separation and evolving from a dynamic liquid-like state into a solid-like stable compartment. Multistep regulation by microtubules controls condensation, ensuring proper Bb formation and oocyte polarity.
