Authors: Overduin M, Mayer B, Rios CB, Baltimore D, Cowburn D

The Src homology 2 (SH2) domain is a recognition motif thought to mediate the association of the cytoplasmic proteins involved in signal transduction by binding to phosphotyrosyl-containing sequences in proteins. Assignments of nearly all 1H and 15N resonances of the SH2 domain from the c-Abl protein-tyrosine kinase have been obtained from homonuclear and heteronuclear NMR experiments. The secondary structure has been elucidated from the pattern of nuclear Overhauser effects, from vicinal coupling constants, and from observation of slowly exchanging amino hydrogens. The secondary structure contains two alpha-helices and eight beta-strands, six of which are arranged in two contiguous, antiparallel beta-sheets. Residues believed to be involved in phosphotyrosyl ligand binding are on a face of one beta-sheet. The alignment of homologous sequences on the basis of secondary structure suggests a conserved global fold in a family of SH2 domains.

VITAL NMR: using chemical shift derived secondary structure information for a limited set of amino acids to assess homology model accuracy VITAL NMR: using chemical shift derived secondary structure information for a limited set of amino acids to assess homology model accuracy Abstract Homology modeling is a powerful tool for predicting protein structures, whose success depends on obtaining a reasonable alignment between a given structural template and the protein sequence being analyzed. In order to leverage greater predictive power for proteins with few structural templates, we have developed a method to rank homology models based upon their compliance to secondary structure derived from experimental solid-state NMR...	nmrlearner	Journal club	0	12-22-2011 06:50 AM
