This work was also our first time doing membrane localization (way to go Cassidy)! And so proud of Bella’s gorgeous Paenibacillus tree showing the distribution of the transmembrane containing Spo0B! Also it’s the lab’s first paper without ribosomes 🫨, but don’t worry - the ribosomes made the Spo0B!

rince & JB Editor's Choice: Lin, Prince & Feaga identified sporulation genes via analyzing almost 1500 genomes. They show that that an unusual membrane-localized variant of Spo0B is found throughout Paenibacillaceae.

The sporulation phosphorelay protein Spo0B is membrane localized in Paenibacillus! The transmembrane domain appears to increase interaction with relay partners. Congrats to former lab undergrad @isabellalin.bsky.social and her grad mentor @cassidyprints.bsky.social

Conservation of sporulation genes and a transmembrane-containing Spo0B variant in Paenibacillus Sporulation is a strategy employed by many bacteria to survive harsh environmental conditions. The genus Paenibacillus includes spore-forming species notorious for spoiling pasteurized dairy products ...

Here we show that >90% of Paenibacillus encode a unique Spo0B with a transmembrane domain! TM domain helps it interact with its phosphorelay partners. Congrats to @isabellalin.bsky.social who left for grad school this week and her mentor @cassidyprints.bsky.social! www.biorxiv.org/content/10.1...

Awesome work from my mentee @isabellalin.bsky.social on sporulation in non-model Bacilli!!

Conservation and evolution of the programmed ribosomal frameshift in prfB across the bacterial domain | mBio Translation termination is catalyzed by one of two release factors in bacteria, RF1 or RF2. It has been known for decades that RF2 levels in Escherichia coli are regulated by a programmed ribosomal frameshift within the prfB gene that encodes RF2. We ...

Latest from the lab! Analysis of everyone’s favorite regulatory mechanism in bacteria — the RF2 programmed frameshift! Likely present in the ancestor of bacteria, use of this mechanism is influenced by stop codon usage! Big congrats to @cassidyprints.bsky.social

Just published the first chapter of my thesis! 🥰

E. coli regulates the levels of a translation release factor (RF2) via a *purposeful* frameshift during translation. We found that most other bacteria do this too and it's likely an ancient mechanism!

YebC2 resolves ribosome stalling and increases fitness of cells lacking EF-P and the ABCF ATPase YfmR Author summary Polyproline motifs are essential structural features of many proteins but are difficult for the ribosome to synthesize. EF-P reduces ribosome pausing at polyproline motifs. Here, we sho...

Latest work from the lab - we identify a translation factor, YebC2, that reduces ribosome stalling in B. subtilis!
