Structure of the bone morphogenetic protein 2 mutant L51P
OverviewOverview
Bone morphogenetic protein-2 (BMP-2) and other members of the TGF-beta, superfamily regulate the development, maintenance and regeneration of, tissues and organs. Binding epitopes for these extracellular signaling, proteins have been defined, but hot spots specifying binding affinity and, specificity have so far not been identified. In this study, mutational and, structural analyses show that epitopes of BMP-2 and the BRIA receptor form, a new type of protein-protein interface. The main chain atoms of Leu 51, and Asp53 of BMP-2 represent a hot spot of binding to BRIA. The BMP-2, variant L51P was deficient in type I receptor binding only, whereas its, overall structure and its binding to type II receptors and modulator, proteins, such as noggin, were unchanged. Thus, the L51P substitution, converts BMP-2 into a receptor-inactive inhibitor of noggin. These results, are relevant for other proteins of the TGF-beta superfamily and provide, useful clues for structure-based drug design.
