Thresholds based on large-scale Y2H reference sets in yeast, fly, and human predicted using ColabFold. See Kim et al. 2025 for iLIS benchmark details. Rank 1 (determined by ipTM) may not have the highest iLIS.

Visualization Script

Fill gaps ≤ residues | Min segment ≥ residues
Gap filling bridges short breaks for continuous cartoon. Min segment removes isolated LIR fragments shorter than the threshold.

How to Use  (Full guide)

Quick Start

  1. Go to FlyPredictome Ortholog Search and search for a human gene
  2. Click a predicted interaction pair to open the detail page
  3. Copy the detail page URL and paste it above
  4. Download the script (.cxc or .pml) and structure file, place both in the same folder
  5. Open the script in ChimeraX (.cxc) or PyMOL (.pml)

AFM-LIS Metrics (Kim et al. 2024, 2025)

iLISintegrated LIS — √(LIS × cLIS)
iLIAintegrated LIA — √(LIA × cLIA), geometric mean of interface area counts
iLISAintegrated LISA — iLIS × iLIA, overall binding strength
LISLocal Interaction Score — normalized PAE confidence (0–1)
cLIScontact-filtered LIS — restricted to direct contacts
LIRLocal Interaction Residues (PAE ≤ 12 Å)
cLIRcontact-filtered LIR (PAE ≤ 12 Å & Cβ ≤ 8 Å)

Confidence Metric (from ColabFold)

ipTMinterface predicted TM-score — global interface confidence from the prediction model

PAE (Predicted Aligned Error) measures how confidently the model predicts the relative position of two residues — lower values indicate higher confidence.
