SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

ipSAE provides more accurate ranking of designed protein binders than ipTM or iPAE, helping researchers prioritize candidates for experimental validation and reduce wasted lab resources. It converts predicted structures and error matrices into chain-pair scores that correlate better with binding success for designed complexes.

Core Features & Use Cases

  • Improved Ranking: Produces ipSAE_min, LIS, and pDockQ metrics to rank binder candidates with higher precision.
  • Multi-model Compatibility: Works with AlphaFold2/AlphaFold3 outputs, BoltzGen/Boltz predictions, and BindCraft-refined models when PAE or equivalent error matrices are available.
  • Practical Thresholds: Typical selection thresholds are ipSAE_min > 0.61 for standard selection and > 0.70 for stringent selection, with LIS and pDockQ recommendations included.
  • Use Case: Filter and prioritize hundreds of binder designs from a BoltzGen campaign to select top candidates for synthesis and experimental screening.

Quick Start

Rank the provided binder designs by computing ipSAE scores and return the top candidates with ipSAE_min above 0.61.

FAQPage Schema
How do I rank protein binders from AlphaFold2 predictions?

To rank protein binders from AlphaFold2 predictions, compute chain-pair ipSAE_min, LIS, and pDockQ scores using the predicted structures and PAE matrices to prioritize candidates for experimental testing.

What is the ipSAE score threshold for selecting designed protein binders?

The ipSAE score threshold for selecting designed protein binders is ipSAE_min > 0.61 for standard selection and > 0.70 for stringent selection, alongside LIS and pDockQ metric recommendations.

Does ipSAE work with BoltzGen and BindCraft binder design outputs?

Yes, ipSAE works with BoltzGen and BindCraft outputs, computing chain-pair ranking scores for predicted protein complexes when PAE or equivalent error matrices are available.

Why use ipSAE instead of ipTM for protein binder ranking?

Use ipSAE instead of ipTM for protein binder ranking because ipSAE provides more accurate chain-pair scores that correlate better with binding success, helping reduce wasted lab resources during experimental validation.

Do I need PAE matrices to compute ipSAE scores for protein complexes?

Yes, you need PAE or equivalent error matrices alongside predicted structures to compute ipSAE_min, LIS, and pDockQ scores for ranking designed protein binders.
