Abstract
The present protocol describes a method by which interactions between G protein-coupled receptors (GPCR) and intracellular proteins can be monitored in real-time and without the use of exogenous labels. The method is based on surface plasmon resonance (SPR) and uses synthetic peptides as mimics of intracellular GPCR domains. These peptides are covalently immobilized onto sensor chips and brought into contact with putative interacting proteins in the flow cells of the SPR instrument. The method allows flexible experimental designs, rapid testing of hypotheses and quantitative analysis of interactions. Relative to other established methods, it provides both an alternative and a complementary approach with several key advantages. The present protocol describes the method step-by-step, using the interaction between the serotonin 5-HT7 receptor and the calcium-binding protein S100B as an example.

Abstract
The effects of intermediate dielectric films on multilayer surface plasmon resonance (SPR) behavior were studied in terms of biosensing applications. Ten simple and complex oxides and fluoride, including MgF(2) and MgO, SiO(2), TiO(2) and complex PZT family dielectric materials, were evaluated. The materials cover a wide range of refractive indices, from 1.19 for the porous silica film to 2.83 for the TiO(2) film. The resonance curves of the multilayer SPR configurations were taken from an angular modulated Kretschmann set-up under a fixed incident wavelength of 543.5 nm. The intermediate dielectric layer has no strong effect on the SPR resonance angle and minimum reflectance at the resonance point. Some intermediate dielectric films, such as MgF(2), porous silica, TiO(2) and PLZT, apparently reduce the width of the resonance curves, resulting in sharper resonance dips. Better performance of the multilayer SPR biosensor incorporating these dielectric films is expected.

Abstract
Chemical proteomics is a powerful methodology for identifying the cellular targets of small molecules, however, it is biased towards abundant proteins. Therefore, quantitative strategies are needed to distinguish between specific and nonspecific interactions. Here, we explore the potential of the combination of surface plasmon resonance (SPR) coupled to liquid chromatography-tandem mass spectrometry (LC-MS/MS) as an alternative approach in chemical proteomics. We coupled cGMP molecules to the SPR chip, and monitored the binding and dissociation of proteins from a human lysate by using sequential elution steps and SPR. The eluted proteins were subsequently identified by LC-MS/MS. Our approach enabled the efficient and selective extraction of low-abundant cyclic-nucleotide-binding proteins such as cGMP-dependent protein kinase, and a quantitative assessment of the less- and nonspecific competitive binding proteins. The data show that SPR-based chemical proteomics is a promising alternative for the efficient specific extraction and quantitative identification of small-molecule-binding proteins from complex mixtures.

Abstract
The majority of fast inhibitory neurotransmission in the CNS is mediated by the GABA type-A (GABAA) receptor, a ligand-gated chloride channel. Of the approximately 20 different subunits composing the hetero-pentameric GABAA receptor, the gamma2 subunit in particular seems to be important in several aspects of GABAA receptor function, including clustering of the receptor at synapses. In this study, we report that the intracellular loop of the gamma2 subunit interacts with itself as well as with gamma1, gamma3 and beta1-3 subunits, but not with the alpha subunits. We further show that gamma2 subunits interact with photolabeled pentameric GABAA receptors composed of alpha1, beta2/3 and gamma2 subunits, and calculate the dissociation constant to be in the micromolar range. By using deletion constructs of the gamma2 subunit in a yeast two-hybrid assay, we identified a 23-amino acid motif that mediates self-association, residues 389-411. We confirmed this interaction motif by inhibiting the interaction in a glutathione-S-transferase pull-down assay by adding a corresponding gamma2-derived peptide. Using similar approaches, we identified the interaction motif in the gamma2 subunit mediating interaction with the beta2 subunit as a 47-amino acid motif that includes the gamma2 self-interacting motif. The identified gamma2 self-association motif is identical to the interaction motif reported between GABAA receptor and GABAA receptor-associated protein (GABARAP). We propose a model for GABAA receptor clustering based on GABARAP and GABAA receptor subunit-subunit interaction.

Abstract
A commercially available miniaturized surface plasmon resonance sensor has been investigated for its applicability to biological interaction analysis. The sensor was found to exhibit excellent repeatability and linearity for high-refractive index solutions and good reproducibility for the binding of proteins. Its detection limit for the monoclonal antibody M1 was found to be 2.1 fmol, which corresponds to a surface concentration of 21 pg/mm2. Simple surface immobilization procedures relying on biotin/avidin or glycoprotein/lectin chemistry have been explored. Equilibrium dissociation constants for the binding of the FLAG peptide to its monoclonal antibody (M1) and for the binding of concanavalin A to a glycoprotein have been determined. The close agreement of these measurements with values obtained by surface fluorescence microscopy and fluorescence correlation spectroscopy helps to validate the use of this device. Thus, this sensor shows promise as an inexpensive, portable, and accurate tool for bioanalytical applications in laboratory and clinical settings.

Abstract
With the introduction of new instruments and improved sensor chip chemistries, surface plasmon resonance (SPR) is finding new applications for molecular interaction studies. Easy access to high-quality kinetic and thermodynamic data for macromolecular binding events is providing insights into the fundamental mechanisms of molecular recognition. Progress is being made to allow larger-scale interaction studies. In addition, combining SPR with other analytical methods is enabling SPR-based analysis of interaction proteomics.

Abstract
We have used surface plasmon resonance (SPR) measurements for the kinetic analysis of G-protein-receptor interaction monitored in real time. Functionally active rhodopsin was immobilized on an SPR surface, with full retention of biochemical specific activity for catalysis of nucleotide exchange on the retinal G-protein alpha subunit, via binding to immobilized concanavalin A. The binding interactions of bovine retinal alpha(t) and beta(1)gamma(1) subunits with rhodopsin measured by SPR were profoundly synergistic. Synergistic binding of the retinal G-protein subunits to rhodopsin was not observed for guanosine 5'-[gamma-thio]triphosphate-bound Galpha(t), nor was binding observed with squid retinal Galpha(q), which is not activated by bovine rhodopsin. The binding affinity (336+/-171 nM; mean value+/-S.D.) of retinal betagamma for rhodopsin in the presence of retinal alpha subunit measured by SPR confirmed the apparent affinity of 254 nM determined previously by nucleotide exchange assays. Binding of beta(1)gamma(1), beta(1)gamma(2), and beta(1)gamma(8-olf) dimers to rhodopsin, independently of the alpha subunit, was readily observable by SPR. Further, these dimers, differing only in their gamma subunit compositions, displayed markedly distinct binding affinities and kinetics. The beta(1)gamma(2) dimer bound with a kinetically determined K(d) of 13+/-3 nM, a value nearly identical with the biochemically determined K(1/2) of 10 nM. The physiologically appropriate beta(1)gamma(1) displayed rapid association and dissociation kinetics, whereas the other beta(1)gamma dimers dissociated at a rate less than 1/100 as fast. Thus rhodopsin interaction with its native signalling partners is both rapid and transient, whereas the interaction of rhodopsin with heterologous Gbetagamma dimers is markedly prolonged. These results suggest that the duration of a G-protein-coupled receptor signalling event is an intrinsic property of the G-protein coupling partners; in particular, the betagamma dimer.

Abstract
The efficient delivery of sample to surface-immobilized sites is a key element in biosensing. For a surface plasmon resonance (SPR) biosensor, this has been addressed by constant flow through a microfluidic system with a sample injection loop (Sjölander, S.; Urbaniczky, C. Anal. Chem. 1991, 63, 2338-2345). The present study describes an alternative mode of sample delivery without constant unidirectional flow. It was implemented on a commercial Biacore X SPR biosensor equipped with a microfluidic cartridge, but with the fluidic handling performed by an externally computer-controlled syringe pump. We demonstrate that sample volumes as low as 2 microL can be reproducibly positioned to cover the sensor surfaces, manipulated in a serial fashion, efficiently mixed by applying an oscillatory flow pattern, and fully recovered. Compared to the traditional continuous unidirectional flow configuration, we found very similar kinetic responses at high analyte concentrations and slightly slower responses at low concentrations, most likely due to depletion of analyte from the small sample volumes due to surface binding. With the antibody-antigen systems tested, binding parameters were obtained that are generally within 10% of those from conventional experiments. In the new configuration, biosensor experiments can be conducted without the usual constraints in the surface contact time that are correlated with sample volume and mass transport rate. This can translate to improved detection limits for slow reactions and can facilitate kinetic and thermodynamic binding studies.
