Abstract
Cellular protein-tyrosine kinases play key roles in signal transduction processes in eukaryotes. SmTK4 was the first Syk kinase identified in a parasite and found to be tissue-specifically transcribed in the gonads of adult Schistosoma mansoni. Functional analyses confirmed its role in oogenesis and spermatogenesis. As an SmTK4 upstream binding partner, the cellular protein-tyrosine kinase SmTK6 was isolated from a yeast two-hybrid library. Phylogenetic analyses performed in this study confirmed the first suggestions of a hybrid character of SmTK6. Biochemical studies made in Xenopus oocytes using inhibitors against Src (herbimycin A) and Abl (imatinib) kinases exhibited a biochemical inhibition profile of SmTK6, which was intermediate of Src and Abl kinases. As SmTK6 upstream interaction partners, we identified among others the known Src kinase SmTK3 and the Venus kinase receptor SmVKR1 of S. mansoni by yeast two-hybrid analyses, all of which co-localized in the gonads. Co-immunoprecipitation experiments confirmed interactions between SmTK6 and SmTK3 or SmVKR1. In Xenopus oocytes, it was finally shown that SmVKR1 but also SmTK3 were able to activate SmTK6 enzymatic activity indicating its functions in a receptor tyrosine kinase signal transduction cascade. These results not only demonstrate an intermediate but Src-biased profile of the unusual kinase SmTK6. They also strongly substantiate previous indications for a kinase complex, consisting of a receptor tyrosine kinase, Syk and Src kinases, which has been hypothesized to be involved in proliferation and differentiation processes in the gonads of schistosomes.

Abstract
Signaling proteins are localized and regulated by Src homology 2 domains which recognize phosphotyrosine-containing sequences. Recently, noncanonical ligands have been proposed for Src homology 2 domains including that of Abl and its breakpoint cluster region fusion, which causes chronic myelogenous leukemia. Here, the Abl Src homology 2 domain's binding sites and affinities for phosphotyrosine- and phosphoserine-containing motifs, phosphoinositides as well as a pyridone-based peptidomimetic inhibitor were determined using nuclear magnetic resonance spectroscopy in order to define their roles. The cognate Crk peptide ligand was bound with an affinity of 69 microM and, like the higher affinity peptidomimetic, engages the phosphotyrosine and +3 hydrophobic pockets while putative phosphoserine-containing breakpoint cluster region ligands are ruled out. Surprisingly, phosphatidylinositol 4, 5 bisphosphate interacts with an overlapping site through an electrostatic mechanism that does not appear to involve hydrophobic insertion into micelles. The conserved Arg36 residue in the FLVRES motif is required for both phosphotyrosine binding and for localization to phosphatidylinositol 4, 5 bisphosphate-containing liposomes, while Arg59 in the betaD strand is necessary for the phosphoinositide interaction. Thus the Src homology 2 domain of Abl, a myristoylated and membrane-localized protein, is able to interact directly with phosphoinositides through a multifunctional basic site that overlaps the phosphotyrosine pocket.

Abstract
The protein kinase ZAP-70 is involved in T-cell activation and interacts with tyrosine-phosphorylated peptide sequences known as immunoreceptor tyrosine activation motifs (ITAMs). We have studied the regulatory phosphorylation sites in the tryptic fragment containing amino acids 485-496 (ALGADDSYYTAR). The four possible peptides with phosphorylation at none, one, or both of the Y-492 and Y-493 tyrosines were specifically synthesized and analyzed by (1)H/(13)C-NMR at 600 MHz using a capillary HPLC-NMR microprobe. Unambiguous discrimination of the peptides was possible via effect of chemical shifts of phosphorylation on the aromatic tyrosine protons. With the microprobe and the detection volume of 1.5 microl, it was possible to perform structure elucidation with the very small amounts available for the various peptides. For the syringe injection, 15 microg of the analyte were used (corresponding to ca 2 mg in classical 5-mm tubes). Capillary HPLC-NMR spectra were recorded in the stopped-flow mode from less than 400 ng of each peptide, using 1D and 2D techniques ((1)H,(1)H-COSY-90, (1)H/(13)C-HSQC, and (1)H/(13)C-HMBC).

Abstract
The epidermal growth factor receptor (EGFR) is a member of the tyrosine kinase family of signalling cell surface molecules. Signalling by this protein is mediated through binding of epidermal growth factor to its extracellular region ultimately leading to phosphorylation of several residues on the intracellular portion of the receptor. The only means of communication between the intracellular and extracellular domains is via the transmembrane region of the protein. In this work we describe the first structural studies of a 34-residue synthetic peptide (hEGFRp), representative of the human EGFR transmembrane region, using two-dimensional and 2H wideline NMR and CD spectroscopies. In water the peptide demonstrated a lack of regular secondary structure and existed as oligomers. Addition of the lipomimetic solvent, trifluoroethanol (TFE), led to the production of monomeric structured species. Analysis of NMR spectra of the hEGFRp indicated that an alpha-helix was present between residues M626 and R647. This observation was reinforced by solid state 2H NMR studies in lipid bilayers which showed typical 'Pake' spectra indicating axially symmetric motion. The helical region in hEGFRp commences four residues later than predicted via hydrophobicity profiles, and extends to include several charged arginine residues which would lie on the cytosolic side of the membrane. These observations provide the first evidence that the transmembrane alpha-helical region in EGFR may not only traverse the membrane but may continue to the cytosolic region near T654, an important phosphorylation site.

Abstract
A set of high-resolution three-dimensional solution structures of the Src homology region-2 (SH2) domain of the growth factor receptor-bound protein-2 was determined using heteronuclear NMR spectroscopy. The NMR data used in this study were collected on a stable monomeric protein solution that was free of protein aggregates and proteolysis. The solution structure was determined based upon a total of 1439 constraints, which included 1326 nuclear Overhauser effect distance constraints, 70 hydrogen bond constraints, and 43 dihedral angle constraints. Distance geometry-simulated annealing calculations followed by energy minimization yielded a family of 18 structures that converged to a root-mean-square deviation of 1.09 A for all backbone atoms and 0.40 A for the backbone atoms of the central beta-sheet. The core structure of the SH2 domain contains an antiparallel beta-sheet flanked by two parallel alpha-helices displaying an overall architecture that is similar to other known SH2 domain structures. This family of NMR structures is compared to the X-ray structure and to another family of NMR solution structures determined under different solution conditions.

Abstract
The growth factor receptor-bound protein-2 (Grb-2) is an adaptor protein that mediates signal transduction pathways. Chemical shift assignments were obtained for the SH2 domain of Grb2 by heteronuclear NMR spectroscopy, employing the uniformly 13C-/15N-enriched protein as well as the protein containing selectively 15N-enriched amino acids. Using the Chemical Shift Index (CSI) method, the chemical shift indices of four nuclei, 1H alpha, 13C alpha, 13C beta and 13CO, were used to derive the secondary structure of the protein. Nuclear Overhauser enhancements (NOEs) were then employed to confirm the secondary structure. The CSI results were compared to the secondary structural elements predicted for the Grb2 SH2 domain from a sequence alignment [Lee et al. (1994) Structure, 2, 423-438]. The core structure of the SH2 domain contains an antiparallel beta-sheet and two alpha-helices. In general, the secondary structural elements determined from the CSI method agree well with those predicted from the sequence alignment.

Abstract
BACKGROUND Recruitment of the intracellular tyrosine kinase Syk to activated immune-response receptors is a critical early step in intracellular signaling. In mast cells, Syk specifically associates with doubly phosphorylated immunoreceptor tyrosine-based activation motifs (ITAMs) that are found within the IgE receptor. The mechanism by which Syk recognizes these motifs is not fully understood. Both Syk SH2 (Src homology 2) domains are required for high-affinity binding to these motifs, but the C-terminal SH2 domain (Syk-C) can function independently and can bind, in isolation, to the tyrosine-phosphorylated IgE receptor in vitro. In order to improve understanding of the cellular function of Syk, we have determined the solution structure of Syk-C complexed with a phosphotyrosine peptide derived from the gamma subunit of the IgE receptor. RESULTS The Syk-C:peptide structure is compared with liganded structures of both the SH2 domain of Src and the C-terminal SH2 domain of ZAP-70 (the 70 kDa zeta-associated protein). The topologies of these domains are similar, although significant differences occur in the loop regions. In the Syk-C structure, the phosphotyrosine and leucine residues of the peptide ligand interact with pockets on the protein, and the intervening residues are extended. CONCLUSIONS Syk-C resembles other SH2 domains in its peptide-binding interactions and overall topology, a result that is consistent with its ability to function as an independent SH2 domain in vitro. This result suggests that Syk-C plays a unique role in the intact Syk protein. The determinants of the binding affinity and selectivity of Syk-C may reside in the least-conserved structural elements that comprise the phosphotyrosine- and leucine-binding sites. These structural features can be exploited for the design of Syk-selective SH2 antagonists for the treatment of allergic disorders and asthma.

Abstract
BACKGROUND The Src homology domains, SH3 and SH2, of Abl protein tyrosine kinase regulate enzymatic activity in vivo. Abl SH3 suppresses kinase activity, whereas Abl SH2 is required for the transforming activity of the activated form of Abl. We expect that the solution structures of Abl SH3, Abl SH2 and Abl SH(32) (a dual domain comprising SH3 and SH2 subdomains) will contribute to a structural basis for understanding the mechanism of the Abl 'regulatory apparatus'. RESULTS We present the solution structure of the free Abl SH3 domain and a structural characterization of the Abl regulatory apparatus, the SH(32) dual domain. The solution structure of Abl SH3 was determined using multidimensional double resonance NMR spectroscopy. It consists of two antiparallel beta sheets packed orthogonally, an arrangement first shown in spectrin SH3. Compared with the crystal structure of the Abl SH3 complexed with a natural ligand, there is no significant difference in overall folding pattern. The structure of the Abl SH(32) dual domain was characterized by NMR spectroscopy using the 1H and 15N resonance assignment of Abl SH3 and Abl SH2. On the basis of the high degree of similarity in chemical shifts and hydrogen/deuterium exchange pattern for the individual domains of SH3 and SH2 compared with those of the SH(32) dual domain, a structural model of the Abl SH(32) regulatory apparatus is suggested. This model is in good agreement with the ligand-binding characteristics of Abl SH3, SH2 and SH(32). The binding constants for isolated SH3 and SH2 domains when binding to natural ligands, measured by intrinsic fluorescence quenching, do not differ significantly from the constants of these domains within SH(32). CONCLUSION The solution structures of free Abl SH3 and Abl SH2, and the structural model of Abl SH(32), provide information about the overall topology of these modular domains. The structural model of Abl SH(32), a monomer, consists of the SH3 and SH2 domains connected by a flexible linker. Sites of ligand binding for the two subdomains are independent.

Abstract
We have developed a competition binding assay to quantify relative affinities of isolated Src-homology 2 (SH2) domains for phosphopeptide sequences. Eleven synthetic 11-12-amino acid phosphopeptides containing YMXM or YVXM recognition motifs bound to a PI 3-kinase p85 SH2 domain with highest affinities, including sequences surrounding phosphorylated tyrosines of the PDGF, CSF-1/c-Fms, and kit-encoded receptors, IRS-1, and polyoma middle T antigens; matched, unphosphorylated sequences did not bind. A scrambled YMXM phosphopeptide or sequences corresponding to the GAP or PLC-gamma SH2 domain binding motifs of the PDGF, FGF, and EGF receptors bound to the p85 SH2 domain with 30-100-fold reduced affinity, indicating that this affinity range confers specificity. Binding specificity was appropriately reversed with an SH2 domain from PLC-gamma: a phosphopeptide corresponding to the site surrounding PDGF receptor Tyr1021 binds with approximately 40-fold higher affinity than a YMXM-phosphopeptide. We conclude that essential features of specific phosphoprotein/SH2 domain interactions can be reconstituted using truncated versions of both the phosphoprotein (a phosphopeptide) and cognate SH2 domain-containing protein (the SH2 domain). SH2 domain binding specificity results from differences in affinity conferred by the linear sequence surrounding phosphotyrosine.
