Structural ensembles beat single predictions in TCR:pMHC generalization study
quaidmorris · x · 2026-07-22
The takeaway from this post is that structural ensembles, not single predicted structures, contain the biophysical signal needed for robust generalization in TCR:pMHC prediction.
- The same idea is claimed to extend beyond AF3 to Boltz, RoseTTAFold, OpenFold, and related models.
- A follow-up note says SHAP highlights key drivers such as iPAEs, iPTMs, and pLDDT.
- The peptide:MHC interface also matters, suggesting both successful presentation and TCR recognition contribute.
- Ensemble means and standard deviations each add independent signal.
