How does a cell remodel the ER membrane into a lipid droplet? Excited to share our new bioRxiv preprint, where we find that regulated opening of the seipin ring defines a functional ER–lipid droplet interface — and identify SMLR1 as a regulator of this transition. www.biorxiv.org/content/10.6...

Mechanistic insights into RNA chaperoning by Ro60 and La autoantigens
Structural and functional analyses elucidate the mechanisms by which two ATP-independent RNA chaperones, Ro60 and La, recognize and unfold misfolded RNAs. Diverse noncoding RNAs are associated with th...

Sorry for the late reply ‪@superbug-slayer.bsky.social ‪@roblavigne.bsky.social‬. Here's a Legionella phage & it likely shaped the emergence of Legionnaires' in the first place! www.science.org/doi/10.1126/... (cryoEM w/ @smlea.bsky.social @justindeme.bsky.social). #phage #legionella #legionnaires
A Twitter conversation from 2019 in search of the elusive Legionella phages.

A central, shared role for disulfide bonds in Bacteroidota protein transport and gliding motility
The gliding motility and Type 9 Secretion Systems (T9SSs) of Bacteroidota share a Power Chain that in current models uses a Hub complex to distribute energy to both the T9SS translocon and a moving gl...
