MHC / HLA Binding Prediction Tool

Prioritize peptide candidates by predicted binding to selected human HLA or mouse MHC targets. Compare percentile rank and predicted affinity, then use the shortlist for downstream presentation, immunogenicity or experimental validation studies.

Human & mouse Class I & Class II Percentile-rank prioritization Research use
MHC Class I MHC Class II Closed-ended binding groove Open-ended binding groove Commonly shorter peptides Longer peptides can extend beyond the groove CD8-oriented presentation pathway CD4-oriented presentation pathway
Class I and Class II are predicted separately because their peptide-binding grooves and antigen-presentation pathways differ.

Prediction workspace

Rank peptide candidates

Predict MHC / HLA Binding

Enter a peptide or protein sequence, select species and MHC class, choose the allele or strain, then return the top-ranked candidate peptides.

A longer protein sequence can be scanned to identify candidate binding peptides.
Select the biological system.
Class I and Class II are analyzed separately.
Choose the available HLA allele or mouse MHC target.
Number of ranked candidates to return.
How to read the result. Lower percentile rank indicates stronger predicted binding relative to the model's reference distribution for the selected target. Predicted binding is a prioritization signal, not proof that the peptide is naturally presented or recognized by T cells.
Enter a sequence and select species, MHC class, and allele/strain to begin.

MHC-I Antigen Processing

Estimate whether Class I peptide candidates are likely to be generated by proteasomal cleavage, transported by TAP, and presented through MHC-I. This analysis uses the same sequence and selected Class I allele above.

Use immunoproteasome when the biological context is uncertain.
What this adds. Processing combines proteasomal cleavage and TAP transport; the total score additionally incorporates MHC-I binding. Higher processing/total scores indicate higher predicted efficiency within this model. This is not proof of natural presentation.
Select Class I and an allele above, then run processing prediction.

pMHC immunogenicity

Class I prioritization

MHC-I pMHC Immunogenicity

Prioritize Class-I peptide-MHC candidates using the IEDB immunogenicity model. The model uses amino-acid properties and peptide position and is best validated for 9-mer peptides.

IEDB notes validation primarily on 9-mers.
Uses the Class-I allele selected in the binding workspace above.
Interpretation. Higher scores prioritize candidates within this model. The score is not a probability and does not prove T-cell recognition.
Select a Class-I target above and run immunogenicity prediction.

WT vs Mutant

Neoepitope comparison

WT vs Mutant / Neoepitope Comparison

Compare substitution-style WT and mutant protein sequences and prioritize changed Class-I peptide windows using the existing binding and immunogenicity predictors.

Uses the Class-I allele selected in the main MHC workspace above.
Scope. This first version is deliberately restricted to equal-length substitution variants. Indels/frameshifts require alignment-aware comparison and are not silently approximated.

Prediction and validation
Rank candidates by predicted binding Candidate Percentile rank PEPTIDE-A lower PEPTIDE-B PEPTIDE-C Higher percentile rank → lower priority in the returned shortlist Use ranking to prioritize experiments, not as a biological endpoint.
Percentile rank is best used as a prioritization measure. Lower-ranked candidates are selected for closer review, not declared confirmed epitopes.
Prediction → validation Binding prediction shortlist candidates Presentation evidence binding / immunopeptidomics T-cell response ELISpot · ICS · multimers The appropriate validation path depends on the scientific question. Prediction is strongest when combined with independent biological evidence.
Binding prediction is a hypothesis-generation step. Presentation and T-cell recognition require additional evidence when they are part of the research claim.
Research use: predicted affinity and percentile rank prioritize candidates; they do not establish natural presentation, T-cell recognition or immunogenicity.
