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

ATTENTION MITO-CALCIUM ENTHUSIASTS: there's a new game in town! This piece highlights a new paper by the Elrod Lab interrogating TMEM65’s role in mitochondrial calcium efflux. The De Stefani and Glancy labs have recently reported similar findings. Congratulations on this important discovery!

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)
