| pubmed-article:21543859 | pubmed:abstractText | The binary ligand-receptor complex of human growth and differentiation factor 5 (GDF5) bound to its type I receptor BMP receptor IA (BRIA) was prepared and crystallized. By utilizing the GDF5 variant R57A, which exhibits a high affinity in the subnanomolar range for BRIA, the binary complex of GDF5R57A bound to the extracellular domain of BRIA could be produced and purified. Crystals of this complex belonged to a monoclinic space group: either I2, with unit-cell parameters a = 63.81, b = 62.85, c = 124.99 Å, ? = 95.9°, or C2, with unit-cell parameters a = 132.17, b = 62.78, c = 63.53 Å, ? = 112.8°. | lld:pubmed |
