Protein Hunter: Fast, Fine-Tuning-Free De Novo Protein Design
Protein Hunter, a fast and fine-tuning-free framework that exploits structure hallucination within diffusion models for de novo protein design. Designing specific interactions between proteins and other biomolecules is complex, often requiring extensive computation to co-optimize sequence and structure. Protein Hunter solves this by introducing a lightweight strategy that achieves high in silico performance, even comparable to AlphaFold3, without the need for model fine-tuning.
How Protein Hunter Works
Protein Hunter is an iterative and computationally lightweight framework that transforms a raw sequence input into a high-quality protein design:
Initial State: The process begins with an all-X sequence, a generic starting point that does not specify any amino acid identity.
Structure Hallucination: It leverages diffusion-based structure prediction models to "hallucinate" reasonable-looking 3D protein structures from this generic sequence.
Iterative Refinement: The model then iteratively refines the initial hallucinated structure through a cycle of sequence re-design and structure re-prediction. This process systematically improves the generated protein until a high-quality design is achieved.
Efficiency: The framework is explicitly designed to be fast and fine-tuning-free, allowing researchers to design complex protein interactions without the heavy computational burden of other methods.
