Identification of putative conserved interaction epitopes in ZPR1 for receptors and SMN complexes. (A) Conservation of residues between ZnF1 and ZnF2 mapped to the surface of ZPR1. (B) Conservation of exposed residues in the ZnF2-B domain modules of ZPR1 homologues. (C) Conservation of residues buried in the interface between ZnF2 and the B domain of ZPR1 homologues.
