| - | The adaptor protein APS is a substrate of the insulin receptor and couples receptor activation with phosphorylation of Cbl to facilitate glucose uptake. The interaction with the activated insulin receptor is mediated by the Src homology 2 (SH2) domain of APS. Here, we present the crystal structure of the APS SH2 domain in complex with the phosphorylated tyrosine kinase domain of the insulin receptor. The structure reveals a novel dimeric configuration of the APS SH2 domain, wherein the C-terminal half of each protomer is structurally divergent from conventional, monomeric SH2 domains. The APS SH2 dimer engages two kinase molecules, with pTyr-1158 of the kinase activation loop bound in the canonical phosphotyrosine binding pocket of the SH2 domain and a second phosphotyrosine, pTyr-1162, coordinated by two lysine residues in beta strand D. This structure provides a molecular visualization of one of the initial downstream recruitment events following insulin activation of its dimeric receptor. | ||
