SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Chai-1 structure prediction provides a practical workflow to predict three-dimensional structures of protein complexes and validate design hypotheses, enabling faster iteration between design and structural assessment.

Core Features & Use Cases

  • End-to-end structure-prediction for protein-protein, protein-ligand, and protein-DNA/RNA interfaces.
  • Generates model artifacts (CIF files) and confidence metrics (ptm, iptm, plddt, pae) suitable for downstream QC and ranking.
  • Supports batch workflows and API/Modal-based execution for scalable design validation.

Quick Start

Submit a complex FASTA to the Chai-1 predictor and review the resulting structures and scores to validate designs.

FAQPage Schema
How do I predict protein complex structures using a FASTA file?

Chai-1 supports structure prediction for protein-protein, protein-ligand, and protein-DNA/RNA complexes. It generates 3D CIF model artifacts and confidence metrics like ptm, iptm, plddt, and pae to validate structural design hypotheses.

What confidence scores are generated for protein structure prediction?

Protein structure prediction workflows generate ptm, iptm, plddt, and pae confidence metrics. These scores evaluate structural quality and enable downstream ranking and compatibility with QC tools like protein-design-qc and ipsae.

Can I run batch protein structure predictions via an API?

Yes, you can run batch protein structure predictions via Modal API execution. This enables scalable design validation for multiple protein complexes, generating CIF models and confidence scores for each submitted FASTA sequence.

What tools can I use for downstream quality control of predicted protein structures?

For downstream quality control of predicted protein structures, use tools like protein-design-qc and ipsae. The workflow outputs CIF models and confidence metrics specifically formatted for compatibility with these QC and ranking applications.

Does Chai-1 structure prediction support protein-ligand and protein-DNA interactions?

Yes, Chai-1 structure prediction supports protein-ligand and protein-DNA interactions alongside protein-protein complexes. It processes these diverse molecular interfaces to generate 3D structural models and validation metrics.
