Repulsive guidance molecules (RGMs) control crucial processes spanning cell motility, adhesion, immune cell regulation and systemic iron metabolism. RGMs signal via two fundamental signaling cascades: the Neogenin (NEO1) and the Bone Morphogenetic Protein (BMP) pathways. Here, we report crystal structures of the N-terminal domains of all human RGM family members in complex with the BMP ligand BMP2, revealing a novel protein fold and a conserved BMP-binding mode. Our structural and functional data suggest a pH-linked mechanism for RGM-activated BMP signaling and offer a rationale for RGM mutations causing juvenile hemochromatosis. We also determined the ternary BMP2–RGM–NEO1 complex crystal structure, which combined with solution scattering and live-cell super-resolution fluorescence microscopy, indicates BMP-induced clustering of the RGM–NEO1 complex. Our results show how RGM acts as the central hub linking BMP and NEO1 and physically connecting these fundamental signaling pathways.
