TCRpMHCmodels predicts the three-dimensional structure of TCR-pMHC class I complexes using comparative modelling. Upon submission, this tool automatically selects the best templates and provides within minutes a complete three-dimensional model. The input must include all protein chains from the TCR-pMHC complex (the TCR alpha chain, the TCR beta chain, the peptide chain and the MHC chain), separated by a fasta header. The tool will automatically detect the chain types.
