Protein (50 μg) were loaded in 7% acrylamide SDS-PAGE gel. Molecular mass standard (KDa) are indicated. Red arrows point SLC7A8/CD98hc heterodimer band as well as the light subunit SLC7A8. Upper panel: Rabbit anti-SLC7A8. Bottom panel: Mouse anti-βactin. ( B ) Pre-Pulse Inhibition of the acoustic startle response (PPI). Mean and SEM are represented. Pulse: 120 dB single pulse. Pre-pulse inhibition test: six different pre-pulse intensities (70 to 90 dB) in pseudo random order with 15 s inter-trial intervals.

    Article Snippet: The S10 lysate was supplemented with 0.0156 mg of tRNA per ml, 0.62 mM ATP, 0.037 mM GTP, 6.22 mM creatine phosphate, 0.0156 mg of creatine kinase per ml, 11.8 mM HEPES (pH 7.6), 1.24 mM dithiothreitol, 15.6 μM complete amino acid mixture (Promega), and 0.156 mM spermidine.

    Second RRM of GRSF-1 is required for mRNA binding in vitro. (A) Coomassie blue-stained denaturing 12% polyacrylamide gel of equal moles (1.25 × 10 −11 mol) of wild-type and mutant GST-GRSF-1 fusion proteins purified by glutathione affinity chromatography from E. coli . (B) UV cross-linking analysis of thrombin-cleaved GRSF-1 (rGRSF-1) and intact wild-type (Wt) and mutant GST-GRSF-1 fusion proteins (1.25 × 10 −11 mol) incubated with radiolabeled NP 5′ UTR RNA (10 6 dpm) in 5 mM HEPES (pH 7.6)-25 mM KCl-2 mM MgCl 2 -5% glycerol-100 mM NaCl-2 mM dithiothreitol-20 U of RNasin (Promega) at 30°C for 15 min. Samples were then exposed to UV light (1.0 J) in a Stratalinker (Stratagene), followed by incubation with 10 mg of RNase A per ml and 2 U of RNase T 1 at 37°C for 30 min. Samples were suspended in 1× Laemmli buffer and separated by SDS-10% PAGE, and the gel was dried and visualized with a Storm 850 phosphorimager (Molecular Dynamics). These data are representative of two independent experiments.

    GRSF-1 binds the conserved A-box of the influenza virus NP 5′ UTR. Shown here is a representative autoradiogram of RNA gel shift analysis of radiolabeled influenza virus NP (lanes 1 to 7) or NP-A (lanes 8 to 14) 5′ UTR RNA incubated with increasing concentrations (50, 100, and 200 ng) of thrombin-cleaved (rGRSF-1) or uncleaved GST-GRSF-1. Proteins were incubated with radiolabeled RNA (100,000 dpm) in buffer that contained 5 mM HEPES (pH 7.6), 25 mM KCl, 2 mM MgCl 2 , 3.8% glycerol, 100 mM NaCl, 0.02 mM dithiothreitol, 2 mM GTP, and 1.5 mM ATP at 30°C for 20 min. Samples were then electrophoresed on a 5% polyacrylamide gel at 4°C and visualized by autoradiography. These data are representative of two independent experiments.
