IPA's Subsidiary BioStrand Completes Integration of 20 Million Proprietary Structural HYFTstm and Accelerates in Silico Drug Discovery Developments


IPA (IMMUNOPRECISE ANTIBODIES LTD.) (the "Company" or "IPA") (NASDAQ: IPA), an advanced biotherapeutic research and technology company, today announced that its subsidiary, BioStrand BV, has completed the full integration of 20 million Structural HYFTs with Deepmind's AlphaFold and META's ESM-2 Fold platforms.

Protein Wars: AlphaFold-2 vs ESM-2 Fold

Recent efforts to predict the three-dimensional structure of a protein using AI are progressing as a solution to the protein folding challenge. A protein's three-dimensional structure can be studied with the same level of accuracy as experimental methods, thanks to AlphaFold, a protein structure analysis AI created by DeepMind, an Alphabet business focused on artificial intelligence. In July 2021, Alphafold became publicly available and is credited with revolutionizing biology.

A searchable database containing the three-dimensional structures of more than 200 million proteins predicted by Alphafold was released in July 2022.

The ESM Metagenomic Atlas, a database that predicted the structure of over 617 million metagenomic proteins, was then presented in November 2022 by Meta AI, a Facebook research team focused on generating knowledge for the AI community. The study of genomes that have been retrieved directly from environmental samples is known as metagenomics.

ESM is a ground-breaking approach developed by Meta AI researchers to predict protein structure. This model is one of the closest alternatives to DeepMind's AlphaFold-2, which reportedly resolved the 50-year-old grand challenge of in silico protein folding. Meta AI has introduced several models throughout the years, and the public can now see its most recent efforts. ESM-2 Fold inference is quicker at enabling the investigation of structural spaces of metagenomic proteins, even though AlphaFold-2 and RoseTTAFold have higher accuracy.

Numerous protein structure prediction models exist in addition to ESM-2 Fold and AlphaFold-2, such as RoseTTAFold, OmegaFold, IntFOLD, RaptorX, and others.

The ESM Fold model from Meta's protein structure prediction AI translates the atoms and molecules that make up the protein into language and predicts the three-dimensional structure from the learning data. The group developed the ESM-2 with 15 billion parameters by extending this model. ESM-2, the largest protein language model to date, employs 2,000 GPUs, and is able to predict the three-dimensional structure of more than 600 million proteins in the ESM metagenomic atlas in just two weeks.

Meta AI's research team claims that while ESM-2's structure prediction speed is up to 60 times faster than AlphaFold's, its prediction accuracy is inferior to that of AlphaFold. This suggests that structure prediction can be scaled to considerably larger databases, according to Meta.

The HYFT Technology

HYFTs are Universal FingerprintTM patterns mined throughout the whole biosphere. When linked together, they form a Knowledge Graph that constitutes over 660 million HYFTs and more than 25 billion relations. The core characteristic is that these HYFTs can connect sequence to structure and function, but also link sequence to all types of textual information such as scientific papers and medical records. Recently, the Company also added more than 20 million structural HYFTs (S_HYFTs) to this Graph, and continuously adds metadata and relations. This strengthened the HYFT-based platforms with the double compounded effect of harnessing the structural prediction capabilities of AlphaFold-2 and ESM-2 as navigational layers for the HYFTs to parse over, while integrating the associated knowledge and speeding up the discovery processes.

Continuously enriching and updating the HYFT graph with the latest novelties is a core characteristic. This means that the number of relationships within the graph is exponentially growing. It provides the HYFT-based LENSai platforms with constantly updated and integrated knowledge relevant within a biological context.

What makes this graph unique is the wealth of explicit information on the whole biosphere that is represented. Since graphs hinge on relationships, they allow one to easily and efficiently determine and visualize the connectedness of different entities in this biosphere. Furthermore, it equips the LENSai platform with an extremely powerful starting point for further application of various AI and machine learning techniques in antibody discovery and precision medicine. The HYFT graph provides a unique intermediate layer between sequences and predictions, allowing new knowledge and insights to be extracted without having the downside of operating in a black box.

From Knowledge Graph to Undiscovered Knowledge

Why does it matter to have a huge knowledge graph covering the whole biosphere? The richness of a graph determines the depth and level of detail of new information and knowledge that can be extracted. Having access to a wealth of 25 billion relationships empowers fine-grained levels of exploration that were not possible before. It opens a whole new world of undiscovered knowledge. In addition to the magnitude of relations, the biological relevance of the information is key. Here, the HYFT knowledge graph's unique ability to connect sequence, structure, function, and literature is unprecedented.
