30-years ago today I started my lab in Bristol Biochemistry, it's been a fun ride! Massive thanks to all those past and present lab members and academic colleagues for their friendship, advice and support.

It is a nice way to end the week: our improved RAB GTPase BioID map now online! www.nature.com/articles/s42... We hope it will be useful to the community, and we're happy to share any reagents!

Add our first pre-print to your reading list? Using AF2 and MD, we've characterised structures and conformational ensembles of human rhomboid proteases - and revealed some surprises along the way. Feel v.lucky to work alongside Bryony & @robincorey.bsky.social! Please share: tinyurl.com/3h8r7f5y

Excited to announce, the 93rd Biochemical Society Harden Conference will be on "Endosomal-lysosomal network dysfunction in neurodegeneration". Come and join us in early September on the beautiful south coast of England. Lots of speaker slots available from submitted abstracts!

Latest endosomal publication with @brettcollins.bsky.social: Rebeka Butkovic's beautiful work identifying a new Commander assembly, the RAB32-LRMDA-Commander, and its role in melanosome biogenesis. Reveals molecular mechanism of human oculocutaneous albinism type 7. www.nature.com/articles/s41...

Structures of EHD2 filaments on curved membranes provide a model for caveolar neck stabilization https://www.biorxiv.org/content/10.1101/2025.06.05.658037v1

Pleased to see Kevin's paper on the Retromer complex interaction with yeast Vps5 and Vps17 proteins now online!

New preprint on kinesin inhibition and activation - collaborative effort across Bristol Biochem and Chemistry with Woolfson and Schaffizel labs and JJ Phillips in Exeter 1/2 www.biorxiv.org/content/10.1...

Pls re-skeet! There's a postdoc job available to join us in Bristol! We're looking for a molecular cell biologist to help us investigate plasma membrane proteostasis in neurons. Apply here by 23 April: www.jobs.ac.uk/job/DMO097/r.... If interested, do contact me and check out grieve-lab.com! Thanks!

SNX-BAR proteins 5 and 6 are required for NCOA7-AS antiviral activity against influenza A virus https://www.biorxiv.org/content/10.1101/2025.04.01.646557v1

Lysosomal acidification is key for cellular health, with impairment linked to aging & neurodegenerative diseases. Lin et al. identify USP45 as a negative regulator of autophagy, inhibiting V-ATPase localization to autolysosomes via Coronin 1B-actin modulation. rupress.org/jcb/article/...

Interested how events are coordinated during #endosome maturation? Check out our latest paper! Congrats Daniel, Samit and Jachen! www.embopress.org/doi/full/10....

Two new lab manuscripts describing new insight into VPS29’s role in Retromer vs Retriever, and the identification of a non-classical Commander pathway in melanosome biogenesis. Both with @BrettCollins.bsky.social lab. www.biorxiv.org/content/10.1... and www.biorxiv.org/content/10.1...

Identification of a VPS29 isoform with restricted association to Retriever and Retromer accessory proteins through auto-inhibition. https://www.biorxiv.org/content/10.1101/2025.02.04.636264v1

Identification of a RAB32-LRMDA-Commander membrane trafficking complex reveals the molecular mechanism of human oculocutaneous albinism type 7 https://www.biorxiv.org/content/10.1101/2025.02.04.636395v1

This is a fantastic route for international post docs to perform research in a UK lab. Bristol Biochemistry would be a great home, including our own endosomal-lysosomal lab. royalsociety.org/grants/newto...

And now onto @carlosantonplagaro.bsky.social from the Pete Cullen lab using BioID to understand the role of Rabs in fate determination in endosomal sorting - great work, Carlos! #UKMT2024

This is an great opportunity. Andrew, his science, and his team are amazing!

Endosome maturation is orchestrated by inside-out proton signaling through a Na+/H+ exchanger and pH-dependent Rab GTPase cycling https://www.biorxiv.org/content/10.1101/2024.12.09.627558v1

Finally my first author preprint at Cullen's lab is out! Amazing collaboration with Kevin and @brettcollins.bsky.social where, by using dedicated proximity proteomics, Biochemistry, crystallography and structural prediction, we show new aspects of human Retromer complex acting as hub for RAB GTPases

Our latest paper with @brettcollins.bsky.social is on bioRxiv. Fantastic work driven by Carlos Anton-Plagaro with unbelievable help from Kai-en Chen in Brett’s lab. A data-rich study with lots of new insight into Retromer, Retriever and potential AD/PD connections. www.biorxiv.org/content/10.1...

Very proud to be involved in this work with the Cullen lab. Carlos's proteomics is some of the nicest I've seen! Very carefully controlled proximity labelling reveals a number of novel Rab GTPase activators and regulatory proteins are directly associated with Retromer on the endosome.
