Today we report single-cell APEX-seq (scAPEX-seq)—a method for unbiased mapping of subcellular transcriptomes at single-cell resolution. It reveals cell states invisible to standard scRNA-seq and identifies regulators of CAR T function that improve solid tumor killing. tinyurl.com/32pf6b8p
Video introduction to our new “Conformational Biasing” method for computational design of mutations that bias proteins towards desired conformational states CB part starts at 14:55 Thanks to Peter Cavanagh and Andrew Xue – amazing graduate students who co-led this work

Can we design mutations that bias proteins towards desired conformational states? Today in @science.org, we introduce Conformational Biasing (CB), a simple and scalable computational method that uses contrastive scoring by inverse folding models to identify conformation-biasing mutations.
Computational design of conformation-biasing mutations to alter protein functions
Conformational biasing (CB) is a rapid and streamlined computational method that uses contrastive scoring by inverse folding models to predict protein variants biased toward desired conformational sta...

Towards CRISPR-based editing of the mitochondrial genome in yeast
Mitochondria, which evolved from symbiotic bacteria, possess their own genomes (mtDNA) and support independent transcription and translation within the organelle. Given the essential role of mtDNA in ...

I'm thrilled to share our work from @weissmanlab.bsky.social (www.sciencedirect.com/science/arti...). We developed LOCL-TL, an optogenetic approach for monitoring localized translation in mammalian cells. LOCL-TL revealed two distinct strategies for mitochondrially localized translation.
Proximity-specific ribosome profiling using LOV-BirA reveals two distinct strategies for mitochondrially-localized translation: one for long coding sequences and one for short. It was a pleasure to contribute to this beautiful work from Jonathan Weissman @weissmanlab.bsky.social and Jingchuan Luo

Directed evolution of LaccID for cell surface proximity labeling and electron microscopy - Nature Chemical Biology
LaccID, an engineered laccase, enables hydrogen-peroxide-free proximity labeling and electron microscopy (EM) in mammalian cells. Notably, LaccID is selectively active at the cell surface, enabling th...

Can a single researcher test over half a million chemical reactions in <3 days? Yes, using Jeff Martell’s new DNA-encoded combinatorial screening platform. Check out his lab’s exciting new preprint 👇
Jeff Martell@jeffmartell.bsky.social · last yr.Excited to share our new preprint, which was years in the making! chemrxiv.org/engage/chemr... New reactions are typically developed by trial and error. How can we speed up this process? Read on to learn how we used DNA scaffolding to perform >500,000 parallel reactions on attomole scale. 1/n
We are hiring a new lab manager! Our wonderful lab manager Albert is headed off to grad school and we are looking to fill his position this summer. This is a great opportunity for a new graduate to spend a couple years immersed in research before applying to PhD or MD programs. 50% of the job is...
Today we report the directed evolution of HUH into rHUH, a sequence-specific covalent protein tag for RNA labeling. rHUH was hard to engineer: the initial HUH template had no RNA activity, so we started with RNA-DNA hybrids. 30 rounds of selection on the yeast surface were required, and 7 cycles of
Tetanus on demand! (not for bioweapons, but for neuroscience research) Tetanus toxin induces paralysis by using a protease to cleave VAMP2, a protein required for synaptic vesicle fusion and neurotransmitter release. To harness this toxicity and use it as a beneficial tool for neuroscience,
