Figure 1. A – Sequence of apelin and Elabela/Toddler peptides4,14; B – Docking of ELA-11 on the apelin receptor; C – Apelin-13 (multicolored atoms) and ELA-11 (green) docking showing overlap in the binding site; D – Ligand interaction diagram showing key close contacts between ELA-11 and the apelin receptor model; ELA indicates Elabela/ Toddler/Apela12.
