Every day we make enough DNA to go to the moon and back. So, all our DNA replication enzymes work fast, right? In our latest preprint, we show that a key enzyme, the clamp loader ATPase RFC, releases ADP much slower than it loads PCNA. What gives? (1/16) doi.org/10.1101/2025...

Hurray, it is finally out! Meet bacteriophage Bxb1 - the subject of my first full-phage cryo-EM study. My structures are beautifully complemented by the Park Lab’s cryo-ET analysis, shedding light on mycobacteriophage structural changes during infection. www.sciencedirect.com/science/arti...

Did you know that there is so much DNA packed inside a phage capsid that the pressure is 10X higher than in a bottle of champagne? In our latest preprint, we wondered how that is contained in a phage that lives at extremely high temperatures. /1 www.biorxiv.org/content/10.1...
Meme describing types of headaches, with the most all encompassing headache being the stress of holding copious amounts of DNA in a phage head.

I'm a little late to the game, but I'm happy to announce that our paper with my @umasschan.bsky.social colleagues in the Travis Thomson lab has now been published in @plosbiology.org! Thanks to all involved on this fun collaboration!

Fun primer with @ForeverYHChang highlighting a lovely Travis Thomson lab paper! Did animals co-opt viral gag for intercellular (trans synaptic) communication? Or did viruses co-opt retrotransposon gags that animals had previously co-opted for intercellular use?

Over 4 years in the making, I am extremely happy to share our pre-print on the “In-cell structure and snapshots of copia retrotransposons in intact tissue”. We used cryo-ET to resolve the copia capsid structure to subnanometer resolution inside cells: www.biorxiv.org/content/10.1...

Check out this new preprint from first author @svenklumpe.bsky.social and coworkers (primarily Plitsko and Beck labs at Max Planck) describing Copia retrotransposon capsids inside cells. Fig 3 is so dope. Look at that capsid array! Beautiful work! 😍🤩 www.biorxiv.org/content/10.1...

I'm back to do an in-depth dive into our most recent work up on biorxiv. Led by the Thomson Lab in the Neurobiology dept, w Yumeng Liu of the Kelch Lab. We find that the retrotransposon Copia forms capsids that antagonize Arc for controlling synaptic plasticity. /1 www.biorxiv.org/content/10.1...

Just in time for Festivus, another paper up on biorxiv. Led by Thomson Lab in Neurobiology dept @ UMass Chan Med School, w Yumeng Liu of the Kelch Lab. We find that the retrotransposon Copia forms capsids that antagonize Arc for controlling synaptic plasticity. www.biorxiv.org/content/10.1...

I’m happy to announce a new paper from the lab. We find numerous differences in the mechanisms of clamp loading in bacteria vs eukaryotes, despite this machinery being amongst the most conserved components of the replication fork. 1/ www.biorxiv.org/content/10.1...
