Ten years ago, the repulsive guidance molecules (RGMs), a family of three glycosylphosphatidylinositol–anchored glycoproteins, were identified as highly specific co-receptors of the bone morphogenetic proteins (BMPs). Newly reported crystal structures provide exciting insights into how RGM co-receptors may modulate BMP signaling.
