Molecular model of the activin A receptor type I (ACVR1) protein (brown and light pink) bound to its inhibitor FK506-binding protein 12 (FKB12, yellow) and an inhibitory drug (rods). ACVR1 plays a role in the bone morphogenic protein (BMP) pathway. A mutant form of the protein is responsible for the rare genetic disease fibrodysplasia ossificans progressiva (FOP). FOP is a disease where fibrous tissues, including muscle, tendons and ligaments, are gradually replaced by bone (ossified). The mutation in ACVR1 decreases its affinity for FKB12, leading to increased activity of the protein and therefore increased production of bone. | |
