Amazing find by @oliverrocks.bsky.social and @pm-mueller.bsky.social , such a cool discovery. Was fun to be involved.

We offer a PostDoc position for a fully funded project on lipid-encoded #lipidtime protein quality-control checkpoints at the Golgi: great collaborators, excellent working & living conditions & benchspace with a view ;) Please share and repost!

I am very happy that the last bit of my doctorial work has reached the stage to be presented in the form of a preprint!

Here we have a look at GGAs and how they might be connected to AP-1 transport. If you enjoy Golgi-endosome transport, please have a look;

The Golgi Network, Volume II This book explores the interaction of Golgi with different organelles such as ER, the vesicular system, and protein complexes that execute these tasks.

A wonderful collection of contemporary topics and perspectives on secretion and Golgi biology edited by Akihiko Nakano and Jaakko Saraste.

New preprint from the lab together with @labvanni.bsky.social. We looked what happens to ER generated free very long chain fatty acids.. VLCFAs are partionig into lipid droplets and are extracted from the hydrophobic core by Fat1.

Organelles do NOT have a single uniform pH.
And if you think they must, because “protons diffuse fast,” this paper is for you.
A thread on why that assumption is wrong; and what we found instead. 🧵 1/n

StayRose: a photostable StayGold derivative red-shifted by genetic code expansion Photobleaching of fluorescent proteins often limits the acquisition of high-quality images in microscopy. StayGold, a novel dimeric green fluorescent protein recently monomerised through sequence engi...

mStayRose is published in JBC 🥳🎉

Congratulations @wsctt.bsky.social @sporemohan.bsky.social and team for the monumental effort to make a non-natural amino acid incorporating fluorescent protein accessible. It's based on mStayGold, bright, and photostable:

Attention membrane traffickers! I'm recruiting a post-doc to my lab in Dundee. We're dissecting the functions of intrinsically disordered domains of COPII coat proteins. We think they control timing of coat assembly and morphology of carriers.

We show that the protein SPG21, mutated in hereditary spastic paraplegia 21, localizes to endolysosomes via RAB7A, where it promotes mTORC1-dependent TFEB phosphorylation, reducing expression of a subset of TFEB regulated genes

Out today in @nature.com: Together with the Honigmann, Shevchenko, Drobot and Hof labs, we present a general workflow for imaging the localization and transport of individual lipids in cells and mapping their metabolism.

It’s incredibly hard to study lipids in biological membranes on the nanoscale. You need near-perfect information on both membrane ultrastructure and lipid density, which usually isn’t attainable. Lipid-CLEM brought to you by @mathilda95.bsky.social changes that.

I have never seen such a red one though, quite impressive!

Love #lipids and #membranes??? Then you cannot miss these seminars tomorrow with two amazing rising ⭐️ ⭐️ @abelljonny.bsky.social @ibudin.bsky.social
