What should I do if my design campaign has a low pass rate?

The skill includes failure recovery trees that suggest specific fixes, such as lowering diffusion noise scales, increasing binder length, or switching to all-atom design tools like BoltzGen.

Can this skill predict actual binding affinity?

No. Research indicates that individual metrics are primarily pre-screening filters. While they eliminate poor designs, composite scoring is required for meaningful ranking, and experimental validation remains necessary.

Does it check for manufacturability?

Yes, it includes checks for expression risks such as odd cysteine counts, deamidation motifs (NG/NS/NT), and hydrophobic runs that could lead to aggregation.

Which software tools does this skill support?

The skill provides thresholds and logic compatible with AlphaFold2, Chai, Boltz, PyRosetta, BioPython, and ESM2-based metrics.

データサイエンスとML

Evaluates and filters protein designs using research-backed metrics for binding, expression, and structural integrity.

The protein-qc skill provides a comprehensive framework for validating de novo protein designs through multi-stage filtering and composite scoring. It helps researchers move beyond individual metrics—which often have weak predictive power—by implementing standardized thresholds for structural confidence (pLDDT), binding quality (ipTM), and biophysical plausibility. With built-in failure recovery trees and diagnostic commands, it streamlines the identification of high-quality candidates for experimental validation while flagging sequence liabilities like deamidation motifs, unpaired cysteines, and aggregation risks.
