Figure Lengend Snippet: Impacts of the binding between BMP2 and IL34 on the ability of BMP2 and IL34 to bind to ACVR2A and MCSFR receptors respectively: importance of stoichiometry and functional consequences on bone formation and resorption. ( A ) ACVR2A receptor binding to BMP2 (“Wrist” site) does not appear to be affected by IL34 binding to the “Knuckle” sites of a BMP2 dimer. ( B ) MCSFR receptor binding to IL34 occurs at a site overlapping the BMP2 “Knuckle” site binding site. Simultaneous binding of BMP2 and MCSFR to IL34 is therefore impossible. ( C ) BMP receptor binding stoichiometry to a BMP2 dimer. The standard binding of two type 1 and two type 2 receptors per dimer (a), is gradually modified by the amount of IL34 present with potential transformation of a “Knuckle” site into a “Wrist”-like site at intermediate concentrations (b), then a second at high IL34 concentrations (c), bearing in mind that IL34 can bind type 2 BMP receptors. ( D ) Schematic representation of the impact of different ratios of BMPs and IL34 on bone formation and resorption.
