    Thermo Fisher gst fusion proteins
    NCL binds to the C-terminal domain of CLTA. (A) Screening of host proteins that interacted with the NCL protein. SDS-PAGE analysis of immunoprecipitation-purified host factors of RK-13 cells that interact with the NCL protein was performed with NCL mAb. The bands were identified by mass spectrometry. In addition, M is a protein marker and the negative control was cell lysates immunoprecipitation-purified with mouse IgG. (B) Validation of the interaction between CLTA and NCL with the IP assay. Proteins in the lysates of RK-13 cells were immunoprecipitated with anti-CLTA mAb, anti-AP2 mAb, or mouse IgG, and then immunoblotted with anti-NCL mAb. β-actin was employed as an internal control. (C) Schematic illustration of the full-length and truncated forms of <t>GST-CLTA</t> for the GST pull-down assay. The numbers indicate aa positions. (D) GST-CLTA proteins were purified on <t>glutathione-sepharose</t> beads and incubated in RK-13 cells lysates containing the NCL protein. After extensive washing, the binding of NCL was determined by western blot analysis with anti-NCL mAb. The GST protein acted as a negative control.

A gel staining with Coomassie Brilliant Blue ( CBB ) was present below to show protein loading. Note that the CT2 segment was markedly phosphorylated by ERK2. c A representative autoradiograph above a CBB staining illustrating phosphorylation of GST-mGluR1a-CT2 by active but not inactive ERK2. d A representative autoradiograph above a CBB staining illustrating phosphorylation of GST-mGluR1a-CT2 in the presence but not absence of ATP. e CIP-mediated dephosphorylation of ERK2-phosphorylated GST-mGluR1a-CT2. All phosphorylation reactions were carried out at 30 °C for 30 min ( b–e ) followed by dephosphorylation reactions (e). The reactions were then subjected to gel electrophoresis followed by autoradiography. Solid and open arrows indicate phosphorylated GST-mGluR1a-CT2 (pGST-mGluR1a-CT2) and Elk-1, respectively. Red stars in CBB staining images ( b–d ) indicate the CT2 and Elk-1 bands that were phosphorylated by ERK2. Note that these bands smeared and shifted upward as a result of slower migration due to phosphorylation

    ALS-FTLD-associated SQSTM1 mutations impact on the recognition of LC3B (SQSTM1 L341V ) or ubiquitin (SQSTM1 <t>G425R</t> ) in vitro. Mutations as indicated (or wild type, WT) were introduced into the full-length <t>GST-SQSTM1</t> sequence and affinity isolation assays (LC3B and ubiquitin on beads) were performed at 37°C. Bacterial lysates containing the GST-SQSTM1 fusions were incubated with glutathione- (G), control- (C), LC3B (LC3), and ubiquitin-Sepharose (Ub) beads and captured proteins were detected by western blotting (anti-SQSTM1 antibodies). A representative blot is shown; see Fig. S1 for quantification of 3 independent experiments.

    RHDV VP60 interacted with the N-terminal domain of NCL. (A) NCL binds to VP60 during RHDV internalization. An IP assay was performed on cell lysates using NCL mAb in RK-13 cells that were infected or uninfected with mRHDV, then immunoblotted with mAbs against NCL or VP60. β-actin was employed as an internal control. The cells uninfected with mRHDV served as negative control. (B) Validation of the interaction of VP60 with NCL by the Co-IP assay.

    Adiponectin and macrophage-associated Irak3 are indispensable molecules in the anti-atherosclerotic properties of PPAR agonists. The schematic draw demonstrates the anti-atherosclerotic properties of the PPARγ agonist rosiglitazone. Treatment with rosiglitazone improves the adipocyte function characterized by a decrease in adipocyte size, a reduction in adipose tissue macrophages and an increased expression of anti-inflammatory adiponectin. The increase in blood adiponectin and de novo adiponectin production in atherosclerotic lesions is necessary for the upregulation of Irak3 in plaque macrophages, which is crucial for the indirect rosiglitazone-mediated decrease in Mcp1 secretion. Abbreviations: Mφ, macrophages; ROS, reactive oxygen species.
