🎲 Our paper on the genetics, energetics, and allostery in proteins with randomized cores and surfaces is out today @science.org!
🧬 By charting a protein’s sequence universe, we could rationalize which versions were kept through evolution – and why many stable ones were not.

Our paper on myxozoan genomes is out now in G3! See thread below for a brief recap (slight change of title from the preprint, same content).

Thank you also to @arunsethuraman.bsky.social for handling the manuscript and @joannamasel.bsky.social for helpful comments.

Allostery is a widespread cause of loss-of-function variant pathogenicity
Allosteric communication between non-contacting sites in proteins plays a fundamental role in biological regulation and drug action. While allosteric gain-of-function variants are known drivers of onc...

Alzheimer’s disease 🧠starts with a molecular domino effect - but what triggers the first piece to fall?
In our new study we cracked open the black box of early protein aggregation, and the findings could reshape how we fight neurodegeneration. 🧵👇

The genetic architecture of an allosteric hormone receptor
Many proteins function as switches, detecting chemicals and transducing their concentrations into cellular responses. Receptor switches are key to the integration of environmental signals, yet it is n...

The genetic architecture of G-protein coupled receptor signaling
G-protein coupled receptors (GPCRs) are the most abundant class of human receptors and drug targets. The vast majority of GPCR drugs bind the conserved orthosteric pocket, which can lead to non-specif...
