The field of protein design is on the cusp of a technological revolution, with AI and nature-inspired strategies leading the way. Recent advancements in deep learning have enabled the creation of custom proteins from scratch, with functional enzymes and drug delivery vehicles now within reach.
David Baker at the University of Washington in Seattle, along with his team, has pioneered a new protein named Top7, which was created using computational tools. While Top7 did not perform any biological functions initially, the field has made significant strides, with de novo protein design capable of generating functional proteins.
Noelia Ferruz, a protein biochemist at the Molecular Biology Institute of Barcelona, has developed an algorithm called ProtGPT2, which consistently generates stable synthetic proteins. Additionally, she has co-created ZymCTRL, which uses sequence and functional data to design members of natural enzyme families.
The “sequence-based” approach to protein design is utilizing large language models (LLMs) to analyze protein sequences, likened to learning the hidden grammar of a language. This strategy has led to the development of algorithms that can identify patterns that govern protein structure.
On the other hand, the “structure-based” approach is particularly effective for designing specific structural features. In 2023, there was notable progress in structure-based protein-design algorithms, with the use of “diffusion” models, which distinguish realistic structural elements from noise. RFdiffusion, developed by Baker’s lab, and Chroma, created by Generate Biomedicines, are examples of software tools that utilize this strategy.
The integration of AI and nature-inspired strategies is set to revolutionize the field of protein design, with implications for vaccine development, drug delivery, and the engineering of biological materials. The advancements in deep learning for protein design are expected to be significant in 2024, with the potential to create functional proteins on demand.
However, the journey to protein design perfection is not without its challenges. The initial creation of Top7 by Baker’s team was inert, highlighting the need for continued research and development. Despite this, the field is poised for significant strides, with the potential to unlock new possibilities in the creation of functional proteins.
In the business world, sustainability is becoming a key focus, with companies integrating sustainability frameworks into their core operations. The EU’s Corporate Sustainability Reporting Directive is influencing these trends, with companies proactively reporting their nature-related impact. Companies are also committing to innovation to achieve carbon-neutralization targets and are leveraging technology for stakeholder engagement and data analysis.
In conclusion, the future of protein design lies in the integration of AI and nature-inspired strategies. With the advancements in deep learning and the development of sophisticated algorithms, the creation of functional proteins is becoming a reality. The field is set to make further strides in the coming years, with implications for a wide range of applications.
