HOP contains three Tpr domains which bind the C-terminal peptide EEVD of Hsp70 and Hsp90<ref>PMID:10786835</ref>. Tpr domain is a TetraPeptide Repeat motif of α-helix pairs involved in protein-protein adhesion. Human HOP protein Tpr domains are: Tpr1 residues 1-118; Tpr2 residues 222-352; Tpr3 residues 356-477.
