Cells have evolved mechanisms to distribute ~10 billion protein molecules subcellular compartments where diverse proteins involved in shared functions must assemble. Here, we demonstrate that with share amino acid sequence codes guide them compartment destinations. A language model, ProtGPS, was developed predicts high performance the localization of human excluded from training set. ProtGPS successfully guided generation novel sequences selectively assemble nucleolus. identified pathological mutations change this code and lead altered proteins. Our results indicate contain not only a folding code, but also previously unrecognized governing their distribution compartments.

Abstract Within drug discovery, the goal of AI scientists and cheminformaticians is to help identify molecular starting points that will develop into safe efficacious drugs while reducing costs, time failure rates. To achieve this goal, it crucial represent molecules in a digital format makes them machine-readable facilitates accurate prediction properties drive decision-making. Over years, representations have evolved from intuitive human-readable formats bespoke numerical descriptors fingerprints, now learned capture patterns salient features across vast chemical spaces. Among these, sequence-based graph-based small become highly popular. However, each approach has strengths weaknesses dimensions such as generality, computational cost, inversibility for generative applications interpretability, which can be critical informing practitioners’ decisions. As discovery landscape evolves, opportunities innovation continue emerge. These include creation high-value, low-data regimes, distillation broader biological knowledge novel modeling up-and-coming therapeutic modalities.

Protein language models trained on evolutionary data have emerged as powerful tools for predictive problems involving protein sequence, structure, and function. However, these overlook decades of research into biophysical factors governing We propose Mutational Effect Transfer Learning (METL), a model framework that unites advanced machine learning modeling. Using the METL framework, we pretrain transformer-based neural networks simulation to capture fundamental relationships between energetics. finetune experimental sequence-function harness signals apply them when predicting properties like thermostability, catalytic activity, fluorescence. excels in challenging engineering tasks generalizing from small training sets position extrapolation, although existing methods train remain many types assays. demonstrate METL's ability design functional green fluorescent variants only 64 examples, showcasing potential biophysics-based engineering.

Protein-ligand binding site prediction is a useful tool for understanding the functional behaviour and potential drug-target interactions of novel protein interest. However, most methods are tested by providing crystallised ligand-bound (holo) structures as input. This testing regime insufficient to understand performance on targets where experimental not available. An alternative option provide computationally predicted structures, but this commonly tested. due training data used, computationally-predicted tend be extremely accurate, often biased toward holo conformation. In study we describe benchmark IF-SitePred, protein-ligand method which based labelling ESM-IF1 language model embeddings combined with point cloud annotation clustering. We show that only IF-SitePred competitive state-of-the-art when predicting sites it performs better proxies proteins low accuracy has been simulated molecular dynamics. Finally, outperforms other if ensembles generated.

Machine learning (ML) models have become increasingly popular for predicting and designing structures properties of peptides proteins. These ML typically use proteins containing only canonical amino acids as the training data. Consequently, these struggle to make accurate predictions new that are absent in data set (e.g., noncanonical acids). One approach improve accuracy is collect more with desired acids. However, this strategy suboptimal may not be easily attainable, additional time required retrain models. Alternatively, extendibility can improved if acid features used representative generalizable unseen Herein, we develop using molecular dynamics (MD) simulation results. Specifically, a given acid, perform MD its dipeptide create based on backbone (ϕ, ψ) distributions electrostatic potentials. We demonstrate enable our accurately predict structural ensembles cyclic present original set. For example, build pentapeptide structures, library 15 test same 15-amino-acid or an extended 50-amino-acid library. When such Morgan fingerprints MACCS keys represent acids, achieve R2 = 0.963 pentapeptides models' performances decrease significantly 0.430 0.508, respectively, when tasked 50 On other hand, model outperforms those keys, 0.700. Overall, instead having data, peptide sequences originally at mere cost performing simulations
