In natural systems, form often determines function. Check out how this model of BLTP3A exhibits the tube-like form that allows it to bridge membranes, and how its partner protein, LC3, docked here near the C-terminus, can serve to orient BLTP3A towards its intended site of action/lipid delivery.
How do lysosomes rapidly adapt to membrane tension to avoid bursting? In this article, @laylanassar.bsky.social and I highlight discoveries from Angela Kim, Spencer Freeman and colleagues who show a role for TMEM63A, a mechanosensitive cation channel in protecting lysosomes doi.org/10.1083/jcb....
Happy to share the latest from the lab, led by Daniel Alvarez, in collaboration with @lizconibear.bsky.social. In this AA-MD tour-de-force, we delve deep into the mechanism and energetics of lipid uptake by bridge-like lipid transfer proteins, and we learn a few interesting things along the way...

Recent @yale.edu research led by @adwolfe.bsky.social, Milind Singh & @dacolon.bsky.social reveals neurons' ability to store glycogen as a backup fuel ⛽️, keeping the brain running under stress — a process called “glycogen-dependent glycolytic plasticity” (GDGP).

Nassar and Ferguson discuss work from Kim et al. showing that TMEM63A protects lysosomes from rupture by acting as a pressure relief valve when membrane te
In eukaryotes, bridge-like lipid-transfer proteins (BLTPs) are central in mediating vesicle-independent lipid transfer between organelles. BLTPs span the cytosolic space between organelles at contact ...
A new Yale study reveals that neurons store their own sugar reserves that kick in to keep the brain functioning during metabolic stress.
