What problem does it solve?
Protein design outputs often contain many candidates with mixed structural confidence, binding potential, and expression risk; this Skill provides standardized metrics, thresholds, and guidance to screen, filter, and rank designs so teams can focus experimental validation on the most promising candidates.
Core Features & Use Cases
- Threshold-based filtering for structural confidence (pLDDT, pTM), interface quality (ipTM, PAE_interaction), and expression metrics (instability, GRAVY).
- Composite scoring and ranking that combines pLDDT, ipTM, PAE, shape complementarity, and language-model plausibility to prioritize designs.
- Design-level checks and heuristics for sequence liabilities (odd cysteines, deamidation motifs, polybasic clusters) and campaign health diagnostics with failure-recovery recommendations.
- Use Case: Run a multi-stage filtering pipeline to reduce thousands of in silico binders to a top candidate set that meets structural, binding, and expression thresholds for experimental testing.
Quick Start
Use the protein-qc skill to filter a design CSV by pLDDT > 0.85, ipTM > 0.5, even cysteine counts, and compute a composite score to select the top candidates.
