Insulin-like growth factor II receptor (IGF2R) is a multifunctional cell surface receptor implicated in tumour suppression. Its growth inhibitory activity has been associated with an ability to bind IGF-II. IGF2R contains 15 homologous extracellular domains, with domain 11 primarily responsible for IGF-II binding. We report a 1.4 A resolution crystal structure of domain 11, solved using the anomalous scattering signal of sulfur. The structure consists of two crossed beta-sheets forming a flattened beta-barrel. Structural analysis identifies the putative IGF-II binding site at one end of the beta-barrel whilst crystal lattice contacts suggest a model for the full-length IGF2R extracellular region. The structure factors and coordinates of IGF2R domain 11 have been deposited in the Protein Data Bank (accession codes 1GP0 and 1GP3).
