Solution structure of the human pp60c-src SH2 domain complexed with a phosphorylated tyrosine pentapeptide.

Human pp60c-src is a cellular nonreceptor tyrosine kinase that participates in cytosolic signal transduction and has been implicated in the development of malignant tumors in the human breast and colon. Signal transduction is mediated by highly specific interactions between the SH2 domain and receptor phosphorylated tyrosine binding motifs. To elucidate the molecular conformation and interactions in solution, a family of highly resolved nuclear magnetic resonance (NMR) structures was determined for the src SH2 domain complexed with a high-affinity phosphorylated pentapeptide, acetyl-p YEEIE-OH. The 23 structures, generated with a distance geometry (DG) and a dynamical simulated annealing (SA) procedure, satisfied 2072 experimental restraints derived from a variety of multifrequency/multidimensional and isotope-filtered NMR data. Superimposition of residues 143-245 upon the mean coordinate set yielded an atomic rmsd of 0.58 +/- 0.09 A for the N, C alpha, C' atoms and 1.04 +/- 0.08 for all the non-hydrogen atoms. Residues in the ordered secondary structure regions superimpose to 0.29 +/- 0.04 A for the N, C alpha, C' and 0.73 +/- 0.08 A for all the non-hydrogen atoms. The angular order parameter calculated for the phi, psi angles was > 0.9 for 81 of the 106 protein residues. The main protein conformational features are three antiparallel beta-strands that traverse a compact core with an alpha-helix on each side of the core near the N- and C-termini. The observed intermolecular nuclear Overhauser effects (NOE) from the pY, +1E, and +3I residues positioned the ligand in an extended conformation across the SH2 domain surface with the pY and +3I side chains inserted into the protein binding pockets. In general, the protein conformation is consistent with previously reported structures of different SH2 domain complexes determined by X-ray crystallography. However, inter- or intramolecular interactions involving the guanidinium side chains of the solvated R alpha A2 or the buried R beta B5 were not observed at pH = 5.5 or 7.0. If such interactions exist in solution, the absence of any confirming data probably arises from rapid exchange with solvent and/or undetermined dynamic components. Thus, the unrestrained R alpha A2 side chain did not show an amino-aromatic interaction or a hydrogen bond to the -1 carbonyl oxygen as observed in the crystal structures. This result is consistent with the solution structure of a different SH2 domain complex. A more detailed comparison between the crystal structure and the NMR-derived solution structures of the same src SH2 domain complex is presented.(ABSTRACT TRUNCATED AT 400 WORDS)

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB code is shown on the right.
