== Publication Abstract from PubMed ==
 +
Interleukin-2 tyrosine kinase (Itk) is a T cell-specific kinase required for a proper immune response following T cell receptor engagement. In addition to the kinase domain, Itk is composed of several noncatalytic regulatory domains, including a Src homology 2 (SH2) domain that contains a conformationally heterogeneous Pro residue. Cis-trans isomerization of a single prolyl imide bond within the SH2 domain mediates conformer-specific ligand recognition that may have functional implications in T cell signaling. To better understand the mechanism by which a proline switch regulates ligand binding, we have used NMR spectroscopy to determine two structures of Itk SH2 corresponding to the cis and trans imide bond-containing conformers. The structures indicate that the heterogeneous Pro residue acts as a hinge that modulates ligand recognition by controlling the relative orientation of protein-binding surfaces.
