Revolutionizing Protein Structure Prediction: An Insight into Large Language Models and the Innovative ProtST Framework

As Seen On

When one ponders the boundless frontiers of scientific enquiry and innovation, two realms that stand out are biotechnology and artificial intelligence. Remarkably, we find the intersection of these two disciplines in the burgeoning field of protein structure prediction. Proteins, the very bricks and mortar of life itself, perform vital roles in countless biological processes, from antibody formation to enzyme operation. Understanding protein structure serves as an essential component in drug discovery and healthcare advancements, making it the proverbial ‘holy grail’ for biomedical researchers. Likewise, Artificial Intelligence and Machine Learning, with their ability to parse vast datasets and discern complex relationships, have found fruitful application in the unraveling of protein mysteries.

One of the remarkable tools crafted from the toolbox of AI is the Large Language Model. These models, renowned for their ability to generate human-like text by comprehending and predicting words in a sequence, provide us with a unique lens to view the world of proteins. In place of alphabets forming words and sentences, Large Language Models consider proteins as sequences of amino acids, or protein language models (PLMs), each with its unique structure and functionality.

The past decade has seen AI and ML steadily permeate the realm of protein structure prediction, bringing with it unprecedented accuracy and efficiency. However, existing PLMs have not been without their limitations- a particular stumbling block has been the acquisition of functionality, the understanding of how a protein’s structure enables it to perform its specific role.

Enter ‘ProtST’: a fresh-off-the-research-bench framework conceived to supplement existing PLMs and propel protein sequence comprehension to new heights. Developed by a team of innovative researchers, ProtST hinges on an ingenious dataset: ‘ProtDescribe.’ This method pairs protein sequences with textual function descriptions, paving the road for a deeper understanding of protein form and function within the context of language models.

ProtST journeys through three significant phases. The first is Unimodal Mask Prediction, a process designed to retain the wealth of co-evolutionary information inherent in protein sequences. By masking specific sections of a protein sequence and training the model to predict these masked parts based on the surrounding context, ProtST utilizes context dependence, a core methodology of language prediction models, in the realm of protein structure.

The model then advances to the second phase: Multimodal Representation Alignment. Herein, the alignment of protein sequences with correlated text representations occurs. Invoking a biological language model, ProtST extracts structured textual representations of the protein properties, thereby facilitating a richer understanding of sequence variability.

The final stop in the ProtST journey is Multimodal Mask Prediction. More than a mere juxtaposition of protein sequences and text representations, this phase aims to define the intricate dependencies between residues in protein sequences and words in their descriptions. Through the creation of multimodal representations, ProtST can articulate these nuanced relationships and offer unique insights about protein functionality.

The launch of frameworks such as ProtST, and adoption of novel datasets like ProtDescribe, underscore the potent influence of Large Language Models in protein structure prediction. The potential impact of this unique fusion of AI and biology is no less than revolutionary. Not only does it serve to deepen our understanding of protein structure and functions, but it also unfolds fresh horizons for drug designing and disease understanding. All in all, it signals a future where understanding the alphabet of life becomes considerably less elusive than it once was.

In concluding our exploration of this exciting fusion of AI and biology, let us pay heed to the words of computer science pioneer Alan Kay: “The best way to predict the future is to invent it.” With AI, ML, and a bundle of innovative frameworks like ProtST at our disposal, the future of protein structure prediction is indeed ours to invent.

Up until working with Casey, we had only had poor to mediocre experiences outsourcing work to agencies. Casey & the team at CJ&CO are the exception to the rule.

Communication was beyond great, his understanding of our vision was phenomenal, and instead of needing babysitting like the other agencies we worked with, he was not only completely dependable but also gave us sound suggestions on how to get better results, at the risk of us not needing him for the initial job we requested (absolute gem).

This has truly been the first time we worked with someone outside of our business that quickly grasped our vision, and that I could completely forget about and would still deliver above expectations.

I honestly can't wait to work in many more projects together!
