== Publication Abstract from PubMed ==
Betaglycan (BG) and endoglin (ENG), homologous co-receptors of the TGF-beta family, potentiate the signaling activity of TGF-beta2 and inhibin A, and BMP-9 and BMP-10, respectively. BG exists as monomer and forms 1:1 growth factor (GF) complexes, while ENG exists as a dimer and forms 2:1 GF complexes. Herein, the structure of the BG orphan domain (BGO) reveals an insertion that blocks the region that the endoglin orphan domain (ENGO) uses to bind BMP-9, preventing it from binding in the same manner. Using binding studies with domain-deleted forms of TGF-beta and BGO, as well as small-angle X-ray scattering data, BGO is shown to bind its cognate GF in an entirely different manner compared with ENGO. The alternative interfaces likely engender BG and ENG with the ability to selectively bind and target their cognate GFs in a unique temporal-spatial manner, without interfering with one another or other TGF-beta family GFs.
