Protein Annotation-Improved Representations (PAIR): A Flexible Fine-Tuning Framework that Employs a Text Decoder to Guide the Fine-Tuning Process of the Encoder

Protein Annotation-Improved Representations (PAIR) is a new approach to enhancing protein function prediction by leveraging text annotations. This method significantly improves the performance of protein models, especially for proteins with low sequence similarity, and shows strong generalization to new tasks. The PAIR framework fine-tunes pre-trained transformer models, like ESM and ProtT5, using high-quality annotations from databases like Swiss-Prot. By integrating a cross-attention module, PAIR allows text tokens to attend to amino acid sequences, improving the relationship between protein sequences and their annotations. This approach outperforms traditional methods like BLAST, and has the potential to handle limited data scenarios, making it a valuable tool in bioinformatics and protein function prediction. PAIR also has the potential to expand its applications to represent other biological entities, such as small molecules and nucleic acids. For companies looking to evolve with AI and stay competitive, leveraging PAIR can provide valuable insights into protein function prediction.
