Benchmark datasets of immune receptor-epitope structural complexes

Table 1 Immune receptor-antigen 3D complexes

Type of complex	Antibody-antigen	TCR-pMHC	MHC-ligand
Total available complexes	2510	296	1107
Complexes with peptidic ligand	2191	181	960
Complexes after filtering	772	154	861
Distinct receptor-epitope pairs	727	98	439

All the receptor-antigen complexes were filtered at 3 Å resolution, along with complexes with missing residues in the antibody or TCR CDR regions. Remaining antibody-antigen complexes with antigens with less than 50 residues were further removed from the dataset. TCR-pMHC and MHC-ligand complexes with core-epitope sequences shorter than 8 residues were removed from the final dataset
