Great tool. After all, it is not because your manuscript is a pre-print that it does not deserve to be beautifully formatted.

Are you looking for a postdoc?
I will be looking for 2-4 people after the summer to join the lab !!
Do not hesitate to reach out and disseminate !!

The second is far more silly. When I finished figure 1, there was an awkward gap between the graphs. So I found something to fill it. But anyway. I am sure they will not be in the final version of the paper... they are very likely the first to the chop when space reatrictions and revisions kick in.

Fair point. I sometimes wonder if sometimes we go too far. The reasons for the pics are two: first, most people will only open the paper. Scan the figures and move on. The more visual info I give them, the better they may remember the paper in the future and come back for a proper read.

Please let us know if you have any comments on our manuscript or in the technique. We are happy to share the things we have produced and/or to collaborate and help with your protein of interest.

This work has the crucial contribution of many talented masters students, who helped optimizing various aspects of the system. At the end, An-Sofie, my lab manager and Katja, a postdoc pushed to story until the end.

๐Ÿงต5/6 โ€” The Big Picture
EndoNB works on endogenous proteins. No rare antibodies. No overexpression.
Itโ€™s scalable and ready to explore the 1000+ surface proteins weโ€™ve barely studied.
Weโ€™re done understanding vesicular trafficking by looking at a handful of model surface proteins.

๐Ÿงต4/6 โ€” Proof of Concept
With EndoNB, we:
โœ… Tracked ligand & antibody effects (Integrin ฮฒ1, TFR, AXL)
โœ… Directly compared receptor uptake (integrin ฮฒ1 vs ฮฒ5)
โœ… Revealed TMEM123โ€™s endocytic behavior
With easy, clean and reproducible results.

๐Ÿงต3/6 โ€” The Solution
We CRISPR-tag the protein of interest with a tiny Alfa-tag.
Then use a nanobody-SNAPtag probe with a self-destruct button (okay, a 3C protease site)
Mix them, let internalize, chill at 4ยฐC and use 3C to cut surface signal.
Whatโ€™s left? Only internalized cargo.

๐Ÿงต2/6 โ€” The Problem
Cell surfaces are packed with proteins constantly moving in and out.
Studying them? Really hard.
Current tools rely on good antibodies (which are rare) and inefficient signal removal protocols.
So, we built something better.

Hi Rhys. Fyi: I could finally solve the issue. The guys on our HPC cluster found a suitable combination of packages.
Thanks!

Every time I solve one incompatibility, another one appears. I solve it, another appears... and the cycle goes on until the whole thing breaks. I need to use a container to install it ( I cannot use conda), which complicates things. All I need is the set of packages that talk to each other.

I am having many errors. Since the release of the git repo, python, numpy, scipy, tensorflow, biopython, pyrosetta, Jax, cuda, jaxlib, haiku, dm-tree (and others) have newer versions that are either not intercompatible or not compatible with the original scripts.

I have wasted the last week of my life trying to install the RFdiffusion/dl_binder_design pipeline in our HPC cluster. The conflicts with the AF2/JAX/pyrosetta dependencies have driven me insane. The info on the GitHub repo is hugely outdated. Is there a kind soul in Bluesky who can help me? please

Scientific leaps cannot be taken overnight - Sigrid Jusรฉlius Foundation There are no quick wins in top medical research. Ville Hietakangas, who studies the effect of food on our physiology, asks for patience and trust from those who fund science.

Professor Ville Hietakangas calls for patience from research funders: the time frame in basic research is long, and financial concerns undermine creativity. Read more in our article: sigridjuselius.fi/en/news/scie...
