Method & Evidence

AimCan deep unsupervised language models generate de novo protein sequences that possess naturalistic amino acid propensities, exhibit globular folding, and explore novel regions of protein space?
MethodComputational modelling and simulation
ProcedureA Transformer-based language model (ProtGPT2) was trained on a large dataset of protein sequences. The model was then used to generate novel protein sequences. These generated sequences were analyzed for natural amino acid propensities, predicted folding patterns (globular vs. disordered), and similarity to known proteins using sequence search algorithms. Furthermore, predicted structures of generated proteins were analyzed using AlphaFold to assess their folding and topological characteristics.

Paragraph starter

The development of AI models like ProtGPT2, as demonstrated by Ferruz et al. (2022), offers a powerful new approach to protein design. By training deep unsupervised language models on vast protein datasets, researchers can generate novel protein sequences that exhibit naturalistic amino acid propensities and predicted globular folding. Crucially, these AI-generated sequences explore previously uncharted regions of protein space, yielding predicted structures with unique topologies not found in current databases. This computational methodology significantly accelerates the exploration of molecular design possibilities, providing a foundation for creating proteins with tailored functionalities for biomedical and environmental applications.
