I am a cell biologist who studies protein quality control and proteostasis in the secretory pathway with emphasis on GPI-anchored proteins, p24-family of proteins, calnexin, endoplasmic reticulum, Golgi, and lysosomes.
What a journey across the world and to the ER! Way to go, Guillaume 👏🏼👏🏼@gthibault.bsky.social
Thank you @jcellsci.bsky.social! It was so much fun chatting with Editor @seemagrewal.bsky.social about my journey, research, and advice for junior scientists.
It’s great that it reads just like our conversation flowed. I sincerely hope it resonates with trainees out there!

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.

New Online! Towards a unified framework for the function of endoplasmic reticulum exit sites
Towards a unified framework for the function of endoplasmic reticulum exit sites
Nature Reviews Molecular Cell Biology, Published online: 29 September 2025; doi:10.1038/s41580-025-00899-0Endoplasmic reticulum exit sites (ERES) are specialized ER subdomains that regulate the export of secreted cargo. This Roadmap explores how ERES integrate biochemical and mechanical signals to coordinate trafficking and proposes a multidisciplinary strategy to investigate their function, including in disease.

The way you perceive this optical illusion may tie back to the visual environment that surrounds you, a recent preprint suggests. scim.ag/4kTxbmd

PSA for NIH R35s: My R35 was administratively withdrawn this year because I broke my Future Research into “Aims” & they said this violated the “Do not submit a Specific Aims page or identify specific aims” policy.
So. Don’t use the word “Aims” in an R35 - use “Projects”. #critical
