Beautiful desert views. Beautiful membrane biology.
Join us for the #FASEB Phospholipids in Aging and Disease SRC in Arizona, July 26–30 2026. Registration is now open!
So much better than a Lipid Droplets conference. Also, we're co-located with FASEB Lipid Droplets 😜
A fascinating look at the frankly bonkers, still-mysterious relationship between master membrane regulator PIP2 and its precursor. Another classic from Min Wu's lab!
Big news for correlative cryogenic SMLM/ET! With my colleague Soheil, we (Mahamid and @jonasries.bsky.social labs) indicate lamella-specific illumination can allow 500-1500x higher laser intensities, opening massive new possibilities for correlative imaging #teamtomo

Proud to share the yeast telomerase structure, led by the talented @hongmiaohu.bsky.social in collaboration with the Wellinger and Chartrand labs. Discovered 37 years ago and took us nearly 7 years but totally worth the wait 😍.

Please spread the word: the Structural Studies Division @mrclmb.bsky.social is looking for a new tenure-track, independent group leader with an exciting plan in any area of Structural (Molecular & Cell) biology, in discovery biology and/or methods development. 🥳

Do you want to know more about how Retromer regulates Rab7 activity in yeast? Of course you do. Check out the new collaboration with Andreas Mayer with work led by Catarina Alves and Kevin Chen.
Excited to share our first collaborative paper of the year- a review on the emerging roles of lipids in flavivirus infection, now published in @cp-trendsmicrobiol.bsky.social. Congrats to Judah (postdoc) for spearheading the work!

Another interesting example of how cPLA2 senses nuclear deformation and controls immune cell behaviour. Since the enzyme adsorbs to hydrophobic lipid packing defects, membrane tension and high positive curvature can have similar effects as membrane tension.

The Retromer coat is conserved in all eukaryotes and is crucial for the correct intracellular sorting of many transmembrane receptors and lysosomal hydrolases. Retromer is an effector of the late endosomal small GTPase RAB7 and is also implicated in its inactivation required for proper endosomal maturation. Here, we explore the role of controlled GTP hydrolysis by the RAB7 ortholog Ypt7 in the formation of Retromer-coated membrane carriers in yeast. Proximity labelling and genetic ablation identify the GTPase Activating Protein (GAP) Gyp6 as a critical regulator of Ypt7 activity in the context or Retromer. Structural studies show that Retromer recruits Gyp6 through its Vps29 subunit, which recognises a specific PL motif and a secondary binding site in the C-terminal domain of Gyp6. This interaction does not occur with other yeast GAPs. Ablation of the Gyp6-Retromer interface or the catalytic activity of Gyp6 leads to the accumulation of tubular structures on endo-lysosomal compartments and to increased association of Ypt7 with Retromer and its cargo Vps10. These results support a model in which Gyp6 controls the switch from Ypt7-dependent Retromer coat assembly and cargo collection to the departure of the carrier through membrane fission and uncoating. ### Competing Interest Statement The authors have declared no competing interest.

Nuclear squeezing triggers lipid signals that help neutrophils stay on course through tight spaces.
Led by Investigator Scientist @hongmiaohu.bsky.social, @kellythd-nguyen.bsky.social’s group in the LMB’s Structural Studies Division have produced the first ever structure of telomerase from yeast.
