RatIE1CORE, humIE1CORE and previously characterized rhesIE1CORE share a common and unique fold.
Ribbon representation of ratIE1 30–392 (A), humIE1 14–382 (B) and rhesIE1 36–395 (C) (PDB: 4WID, chain B). The helices are colored from blue to pink for ratIE1 and from blue to red for humIE1 and rhesIE1. N- and C-terminal residues as well as residues flanking chain breaks are labeled.
