A team of scientists from the University Health Network – Canada’s Hospital, Arc Institute and Vector Institute developed BioReason-Pro to tackle one of the greatest challenges in biology: protein function prediction. Unlike existing AI tools, which give baffling black-box predictions, BioReason-Pro<\/strong> generates structured reasoning that explains why a protein is assigned a function. By integrating protein embeddings and gene ontology via GO-GPT, it managed to achieve 73.6% Fmax on GO term prediction and scored 8\/10 from LLM judges on functional summaries, proving its expert-level biological reasoning.<\/em><\/p>\n\n\n\n

Assigning a function to a protein is the process of predicting what a protein does based on its sequence similarities and structure. It is essential because most proteins discovered in genomes have unknown functions, and accurate annotation speeds up drug discovery, disease research, and medicine development. But the challenge stands as less than 1% of known protein sequences have experimentally verified functions, leaving a massive gap in biological knowledge.<\/p>\n\n\n\n

As genomic sequencing produces millions of protein sequences, far beyond what labs can test experimentally, AI can be critical for computational protein function annotation. While computational approaches to this issue already exist, they rely on shallow sequence similarities or often treat prediction as isolated classification tasks.<\/p>\n\n\n\n

They miss the integrative reasoning across sequence, structure, domains, and interactions that human experts use. This makes BioReason-Pro stand out as not just another AI tool but a multimodal<\/a> reasoning LLM for protein function prediction.<\/p>\n\n\n\n

How Researchers Built a Biology Language Multimodal Model<\/h2>\n\n\n\n

Domain biologists determine a protein’s function by combining sequences, structures, architectures, evolutions, interactions, etc. BioReason-Pro is designed to mimic a similar chain-of-thought reasoning that expert biologists use and reason about the protein’s function in natural language.<\/p>\n\n\n\n

Hence, the researchers came up with a multimodal large language model having the following components, ensuring BioReason-Pro isn’t just an abstract AI model:<\/p>\n\n\n\n
