☕Two studies show that the ER-associated protein CLN8 catalyses the acyl CoA-dependent acylation of glycerophosphoglycerol, producing lysophosphatidylglycerol, which is then converted into BMP. These results provide insight into CLN8 Batten disease. www.nature.com/articles/s41...

These results suggest that cells are responsive to curvature elastic stress that nonbilayer lipids impose and regulate lipid metabolism accordingly. This is central for everyday metabolic decisions, like which phospholipids to make through competing pathways.

Soon to be defending PhD student Daniel Milshteyn showed that they do so, but through different mechanisms. Yeast increase synthesis of PI - a poorly characterized lipid that we show promotes negative curvature - while cancer cells increase ether lipids and long, unsaturated chains.

Itay Budin @ibudin.bsky.social · 01/05/2026
We asked if cells monitor and maintain this facet of lipid biophysics. To do so, we coupled extreme pressures - which we previously showed drive curvature-driven adaptation in marine animals - with SAXS/spectroscopy and lipidomics to test if "common" cells respond to acute reductions in curvature.

Itay Budin @ibudin.bsky.social · 01/05/2026
Lipids come in many chemistries and molecular shapes. Many are non-bilayer in nature - they have an intrinsic curvature that prefers folding up into tubes instead of sheets. Paradoxically, cells need these to for their membranes to pinch and proteins to wiggle. Real cell membranes are quite complex!

What membrane properties do cells maintain through regulation of lipid metabolism? In a new paper, we identify intrinsic curvature stress as one such parameter and show how different (eukaryotic) cell types employ different lipids to do that www.cell.com/cell-reports...

She found that 1-deoxy species accumulate in the ER, likely to impairment in their vesicular trafficking. She then showed that their buildup alters ER membrane fluidity, which alters protein cargo secretion kinetics, and properties of ER exit sites.

I am super excited to announce that we have a tenure-track faculty position in biophysics open in the Department of Physics at Carnegie Mellon! 🧪 Interfolio link: apply.interfolio.com/174360 PLEASE, share widely across the blue skies! Let me briefly explain what we're looking for: 1/10
Tenure-track Position in Biophysics at Carnegie Mellon University, Department of Physics

Location: Pittsburgh, PA
Open Date: Sep 19, 2025

Description
The Department of Physics at Carnegie Mellon University invites applications for a tenure-track faculty position in biophysics. The appointment is intended to be at the Assistant Professor level, but exceptional candidates at a higher level may also be considered. We seek outstanding candidates with a strong record in cellular and subcellular biophysics. Topics of particular interest include, but are not limited to, uncovering how key characteristics of living systems arise from the interplay between supramolecular cellular structures, how the emergent cellular circuitry defines goals and enables robust decision making, and how metabolic resources are allocated. This encompasses understanding of how information is learned, stored, transduced, and processed across subcellular structures. Applicants with theoretical, data science, or experimental backgrounds within biological physics are encouraged to apply. The ideal candidate will strengthen and extend research programs of current biophysics faculty in the Department of Physics and collaborate with broader life science activities across many departments at CMU and the wider Pittsburgh area.

Are the lipids associated with static protein structures there as long-lived ligands or an effect of preferential solvation? This computational-experimental framework shows the way! #lipidtime #compchem www.nature.com/articles/s41...
nature.com
Molecular basis for the regulation of membrane proteins through preferential lipid solvation - Nature Chemical Biology
Static protein structures can capture the association of lipids, but it is unclear whether the association is due to lipids acting as long-lived ligands or the solvation of preferred lipids around the protein. A computational-experimental framework has now shown that for the protein CLC-ec1, it is the change in lipid solvation energies that drives dimerization, with preferred lipids around the protein modulating this driving force.
