Single molecule studies from Arda Mizrak in the Farese/Walther @msk & Harper Labs @harvardcellbio.bsky.social shows how lipid droplet proteins track through ER networks to ultimately partition into nanodomains on droplets, dependent upon Trp-containing hairpin motifs www.nature.com/articles/s41...

Mizrak et al. use single-molecule tracking to dissect mechanisms of protein targeting to lipid droplets. They show that nanodomain-based confinement drives selective protein accumulation on lipid drop...
So excited to share our new paper out today in @nature.com - 'LASER couples damage sensing to ESCRT assembly for lysosome repair'. This was an amazing collaborative effort with Claire Goul during our time in @robzonculab.bsky.social : www.nature.com/articles/s41...

Finally out in @Cellcellpress!
Proteins with long IDRs are prone to misfolding during protein synthesis.
This is prevented by mRNA 3′UTRs that act as mRNA-based IDR chaperones.

The first cut is the deepest: Cleavable signal peptides direct thousands of different nascent proteins to the endoplasmic reticulum. Oddly, SPs are all different and nevertheless cleaved with exquisite specificity. Our new cryo-EM structures + MD solve this paradox:

ATG8 conjugation on damaged lysosomes triggers rapid assembly of a protein complex containing TFG, which directs lysosomal membrane repair by recruiting ESCRT proteins to sites of damage.

Signal peptides are highly variable, yet the signal peptidase complex processes them with remarkable specificity. Here, authors combine cryo-EM, molecular dynamics simulations and modeling to reveal a...
Highly conserved mRNA 3′ UTRs act as co-translational chaperones for intrinsically
disordered regions (IDRs), preventing inter-domain misfolding and enabling biogenesis
of fully active proteins.

How do sperm and egg fuse? Surprisingly, we still don’t fully know…
Our field has uncovered many pieces of the fertilization puzzle, but not how they fit together.
We identify ✨ SPARK ✨ - a conserved sperm complex that couples sperm-egg binding to fusion.

NSUN2 is an enzyme that adds a small chemical mark to RNA molecules and uniquely selects its targets based on specific sequence patterns and structural features.
