Minis, aka spontaneous synaptic neurotransmitter vesicle release, was long dismissed as noise. Our new 📄 using optical electrophysiology shows minis are not spontaneous at all. They're an independent release modality regulated by Unc-5 & critical for synapse preservation 👉 doi.org/10.64898/202...

Excited to share our new study on CpG islands (CGIs) regulation by transcription factors (TFs)! CGIs drive most transcription initiation with unclear regulation. We find that chromatin-opening TFs are key players—following a surprisingly simple rule. 🧵 www.biorxiv.org/content/10.6... 1/9

Transposable elements—or “jumping genes”—are emerging as key regulators of development. In a new review in Advances in Genetics, researchers from the Jachowicz lab at IMBA show how these mobile DNA sequences act as a dynamic layer of gene regulation: www.sciencedirect.com/science/chap...

Welcome to Day 3 of #EMBOMobileGenome 🙌🏼 While this morning's session is already underway, here's a few snaps from yesterday's 🔸last minute breakthrough talk 🔸 ➡️ 'Transposable element co-option drives transcription factor neofunctionalization' presented by Olga Rosspopoff (EPFL, Switzerland)

Lab’s first paper is out!! We show the first structures of #Asgard #chromatin by #cryo-EM 🧬❄️ Asgard histones form closed and open hypernucleosomes. Closed are conserved across #Archaea, while open resemble eukaryotic H3–H4 octasomes and are Asgard-specific. More here: www.cell.com/molecular-ce...
