Excited to share the published version of our work by @ryanfeathers.bsky.social and @rvig.bsky.social on the structural basis for activation of Rab6 by the Ric1-Rgp1 complex! rdcu.be/d2mu3

Here is an updated thread about the paper we first shared on that older platform when we posted the preprint

TMC1/2 activation by mechanical forces in cell lines is compelling! The hearing field has struggled with membrane expression of these proteins, but a CRISPR screen offers a clever workaround. Excited to see if another lab can replicate these findings.
www.cell.com/neuron/fullt...
Human TMC1 and TMC2 are mechanically gated ion channels
Fu et al. showed that point mutations in MmTMC1/2 are localized in plasma membrane, and knockdown of UROD, RGP1, or ARL1 promotes plasma membrane localization of HsTMC1/2 in heterologous cells. HsTMC1/2 are activated by mechanical stimuli and function as pore-forming ion channels, supporting their roles as mechanotransduction channels in hair cells.

The “Gentiane-Express” of the “Chemins de Fer de la Haute-Auvergne”: former #SNCF 🇫🇷 diesel units are working tourist trains on this scenic line in the #Cantal Mountains area in South-Central France.

Taken together, our findings allow us to model the orientation of Ric1-Rgp1 on the Golgi membrane and understand how it activates Rab6. (9/10)

Oct 6th will be a #SUPERMOON - the first of 2025.

This: last #weekend @ the farewell of #Berlin ´s #kitefestival :)

+ the night train La Rochelle - St-Gervais.

Via Ussel and Clermont F, there were:

- 1 DMU (RGP1) converted into Corail "Ventadour" in 1982

- 1 Express Bordeaux SJ - Vichy.

Today, what's left? 🙃😬😭

2-hr headway IC (Arcachon) Bordeaux SJ - Lyon P wouldn't hurt.

Rapide 37-38
"Le Genevois"
(Paris GdL ↔️ Genève C)

1st-class only, supplement payable

The train ran outbound in the morning, and inbound in the afternoon and early-evening.

RGP1 (X-2700) in ex-TEE version (2+1 seating, larger kitchen, 🛂🛃 compartments).

Those had quit TEE duties on 30 May 1965.

A Look Back on MASKulinity
The end of an era is upon us! This is MASKulinity’s series finale episode...maybe just for now. It is Samantha’s farewell episode (Remoy may return), and RGP1  interviews her about MASKulinity Podcast, including a trip down memory lane… Remoy starts out by asking why Samantha wanted to start this podcast. Samantha remembers the inciting incident and the events that followed. She talks about her motivations for engineering the show and what she wanted for her and for you, the listeners, to get out of it. She reveals that her motivations were not just for men. Remoy also asks why Samantha tapped him specifically to do it. She shares the importance of this conversation. She shares her hopes for men and masculinity going forward and how that has changed over the years. For a brief walk down memory lane, Samantha chooses three clips from episodes over the last five seasons as friendly reminders. In Season 4, the hosts got into why Phil Dunphy is the perfect character to explore MASKulinity In Season 3, sex educator Wazina Zondon and reproductive justice advocate Andrew Stern of NIRH (at the time) had stopped by the pod to talk sex education with us Why are folks so afraid to talk to boys about anything, but specifically, about sex? In Season 1, we talked about why men fight… Samantha had to find out whether Remoy had finally been in one. Is men wanting to fight innate or conditioning? Samantha takes a moment to thank you, listeners, for sticking with the podcast all these years. Thank you for giving a shit! Remoy thanks Samantha for spawning this podcast and inviting him along this adventure. Lastly, Samantha may be exiting, but the show may not end! It’s just a see you later for now…. If you know anyone who can support the production of this conversation in any way, please let us know! Samantha will monitor emails - maskulinitypodcast@gmail.com - and socials for a while. You can find us at @maskulinitypod on all platforms. To reach Samantha directly, you can find her on Threads or IG at @samanthal_n. Thank you so much for listening! Referenced on this episode: The Brock Turner case that started it all In TV Dads , we talked about why Phil Dunphy and comedy help us see masculinity in a different light That time we talked about sex education and reproductive justice and how little men and boys know about it Men Got Issues - our episode from Season 1 where we talked about why men fight Report on Homicide of trans women Samantha references our conversation with Trevor Mayoh where he mentions providing on off-ramp out of MASKulinity for men

Ryan also identified a conserved amphipathic alpha-helix within Rgp1 that is flexibly linked to the bulk of the complex and likely plays a role in membrane binding. Removal of this helix significantly reduces the Golgi localization of the complex in cells. (8/10)

Surprisingly, C-terminal HVD of Rab6 binds to a conserved surface of the Rgp1 arrestin fold. We found the HVD sequence is important for activation in cells and also for nucleotide exchange catalyzed by Ric1-Rgp1 in vitro, indicating that binding to the HVD is important for Ric1-Rgp1 function. (6/10)

@ryanfeathers.bsky.social used #cryoEM to determine the structural basis of the Rab6 activation process. Ryan’s structure reveals the architecture of the complex and provides a mechanistic explanation for Ric1-Rgp1 function. (3/10)

Rab6 is a central regulator of the Golgi, important for trafficking and autophagy. Rab6 is activated by its GEF, the Ric1-Rgp1 complex, but it was unknown how this complex performs nucleotide exchange to activate Rab6. (2/10)
