Excited to share our new preprint! biorxiv.org/content/10.6... We know that mitochondria make contacts with organelles, but determining whether these contacts establish functionally distinct mitochondrial populations has been challenging.

A Modular Platform for Purification of Organelle-associated Mitochondria Reveals Functional Specialization at Organelle Contact Sites

Mitochondria perform diverse metabolic and signaling functions, yet how these activities are spatially organized within the mitochondrial network of cells remains poorly understood. Organelle contact ...

Genuinely thrilled to share our new story with the world - an amazing collaboration with @profsharona.bsky.social and Bill Zagotta using their innovative FRET technique to study mitofusin conformational changes. Huge credit to Sophie Hurwitz for tackling this project. urldefense.com/v3/__https:/...

Structural insights into GTP-coupled conformational changes in Mfn1 revealed by time-resolved transition metal ion FRET.

Outer mitochondrial membrane fusion is mediated by the mitofusin paralogs Mfn1 and Mfn2. Nucleotide-driven self-assembly and conformational changes are required for regulated membrane fusion activity,...

Excited to share new work led by outstanding former grad student Kübra Akkaya! We show that Stearoyl-CoA Desaturases (SCDs) regulate intestinal stem and progenitor cell proliferation by balancing fatty acids, sustaining epithelial homeostasis and regeneration.

Hello! Ever wonder what's "talking to" your favorite transcript, but were too scared to ask? In our review in @cp-cellreports.bsky.social, @mardakheh.bsky.social and I highlight new RNA-focused tools for discovering RNA interactions across organizational scales. Checkit! tinyurl.com/ydn6e3ac

NEWS & VIEWS | @yasesancak.bsky.social (U Washington): A new study shows that the mitochondrial protein TMEM65 has a central role in efflux of calcium ions from the mitochondria. https://bit.ly/3Sdndzq ?utm_source=bluesky&utm_medium=social&utm_campaign=natmetab

It's my great pleasure to present the next big preprint from SheqLab! An exciting application of our O-MAP platform that I hope will transform the study of nuclear architecture. If you've ever wanted to dissect the subnuclear "neighborhood" around an individual locus, read on! (1/30)
