Excited to share a new pre-print on a joint study between my group and @chembiobryan.bsky.social‬! Directed Evolution of Enzymes for Bioorthogonal Chemistry Using Acid Chloride Proximity Labeling. chemrxiv.org/engage/chemr... 1/n

Directed Evolution of Enzymes for Bioorthogonal Chemistry Using Acid Chloride Proximity Labeling
Combining bioorthogonal protecting groups with localized catalysts that can unmask them is a powerful approach to spatially and temporally modulate molecular activity. Enzymes are appealing catalysts ...

First copies of my book are here!! As a new faculty member, I realized that in addition to my research job, I also had a leadership job…and I wasn’t prepared for that. This book is the guide I wish I’d had then, with the goal of helping others now.   jenheemstra.com/book

New preprint! We solve a mystery you didn't know existed. Mitotic cells lack new transcription but require ongoing translation. Interphase mRNA half life is only 2-4 hrs. So how do cells arrest in mitosis for hours without depleting their transcriptomes? www.biorxiv.org/content/10.1...

Global inhibition of deadenylation stabilizes the transcriptome in mitotic cells
In the presence of cell division errors, mammalian cells can pause in mitosis for tens of hours with little to no transcription, while still requiring continued translation for viability. These unique...

Awesome to hear so much great science today at the New York Academy Chemical Biology Year-End Symposium, and proud of grad student Jessie Mohsen, who gave an awesome talk on an overlapping, stress-response microprotein in E. coli. Thanks to @davidlabmsk.bsky.social and the rest of the organizers!

I have been trying to find the time to move away from the polical hellscape we find ourselves in to finish and share a bluetorial about science. This helps me remember what this is all about. Ironically, it is about the treatment of pain.
