A dark brown dog with a graying muzzle stands on a couch, facing the camera with wide, shiny eyes and its tongue playfully sticking out. The dog wears a collar with tags, and a pink blanket is draped beside it. Soft daylight from a nearby window illuminates the cozy indoor scene.

I don't think you non-science people realize what it takes to get a grant funded by NIH. Started experiments in Sept 2021 to generate 3 new mouse mutants to model human disease. Prelim dara shows they have relevant disease phenotypes worthy of study. Need a small grant first to characterize /1

How many crystal structures do you need to trust your docking results? It turns out, if you know how your main scaffold binds in the pocket, not that many! Check out this work from recently-defended lab member @keysandcompounds.bsky.social

Composite image illustrating enzyme inhibition concepts with a black dog in different poses:

Top-left: The dog wears a pink flying disc on its head, labeled “Non-competitive (allosteric) inhibition (E–Inc).”
Center: The dog in a tub, tongue out, labeled “E,” connected to “E–S” (enzyme–substrate).
Top-right: The dog holding a yellow tennis ball, labeled “Competitive inhibition (E–Ic).”
Bottom-center: The dog chewing a blue ball, labeled “Substrate binding.” Arrows and labels show the relationships between each form of the enzyme.

Composite image demonstrating “good” versus “bad” enzyme–substrate binding with the same black dog:

Left: The dog with a blue ball in its mouth, labeled “E–Sᵍ” (“bad” binding mode).
Center-left: The dog in a tub with tongue out, labeled “E.”
Center-right: The dog holding a blue ball in a more controlled way, labeled “E–S” (“good” binding mode).
Far right: The dog beside shredded toy pieces, labeled “E + P” (product formation). Text labels and arrows illustrate the transition from enzyme–substrate complexes to products.

It's important to communicate to the public the importance of basic science. Coco is happy to help explain drug binding mechanisms and enzyme kinetics basics:

Figure 1 from arXiv preprint https://doi.org/10.1101/2025.01.06.631610

Fig. 1 Espaloma is an end-to-end differentiable molecular mechanics parameter assignment scheme for arbitrary organic molecules. Espaloma (extensible surrogate potential optimized by message-passing) is a modular approach for directly computing molecular mechanics force field parameters FFF from a chemical graph G such as a small molecule or biopolymer via a process that is fully differentiable in the model parameters FNN. In Stage 1, a graph neural network is used to generate continuous latent atom embeddings describing local chemical environments from the chemical graph. In Stage 2, these atom embeddings are transformed into feature vectors that preserve appropriate symmetries for atom, bond, angle, and proper/improper torsion inference via Janossy pooling.54 In Stage 3, molecular mechanics parameters are directly predicted from these feature vectors using feed-forward neural networks. This parameter assignment process is performed once per molecular species, allowing the potential energy to be rapidly computed using standard molecular mechanics or molecular dynamics frameworks thereafter. The collection of parameters FNN describing the espaloma model can be considered as the equivalent complete specification of a traditional molecular mechanics force field such as GAFF38,39/AM1-BCC55,56 in that it encodes the equivalent of traditional typing rules, parameter assignment tables, and even partial charge models. Reproduced from ref. 49 with permission from the Royal Society of Chemistry.

Everything is chaos, but I wanted to share some awesome recent science from the lab that hints at where the future of biomolecular simulation is headed:

Foundation simulation models that can be fine-tuned to experimental free energy data to produce systematically more accurate predictions.
