    GE Healthcare pgex 4t 1
    Cloning strategies for cloning the paracoccin ORF for expression. The left panel shows the standard strategy, with PCR amplification of the largest exon, restriction endonuclease digestion, and cloning into the expression vector <t>pGEX-4T-1.</t> The positions of the exons are displayed on the map of the gene. Genomic DNA template was extracted from P. brasiliensis strain Pb18. Agarose gel electrophoresis (mid-left) shows the corresponding band amplified by PCR. The exon 4 amplicon was cloned by Bam HI and Eco RI digestion. The right panel shows the strategy for synthesis of the predicted paracoccin sequence fused with the 5′-UTR elements for transcription in the vector pUC57. Green arrow, T7 promoter; black box, lacO (lac operator); and red box, the phage T7 trailer sequence for ribosome binding.

    Cloning strategies for cloning the paracoccin ORF for expression. The left panel shows the standard strategy, with PCR amplification of the largest exon, restriction endonuclease digestion, and cloning into the expression vector pGEX-4T-1. The positions of the exons are displayed on the map of the gene. Genomic DNA template was extracted from P. brasiliensis strain Pb18. Agarose gel electrophoresis (mid-left) shows the corresponding band amplified by PCR. The exon 4 amplicon was cloned by Bam HI and Eco RI digestion. The right panel shows the strategy for synthesis of the predicted paracoccin sequence fused with the 5′-UTR elements for transcription in the vector pUC57.

    Schematic diagram of the constructs used for CVA VP1 protein expression . (A) Schematic representation of the VP1 protein variants and expression vectors used in this study. The designations of the VP1 protein and its expression vectors are indicated, a, b and c. The first two constructs, a and b, contained the full-length VP1 gene cloned into vectors pET28a and pGEX-4T-1, for expression of VP1 protein with a six-histidine (6 × His) tag and glutathione-s-transferase (GST) tag at its N-terminus, respectively. Construct c contained VP1 gene with codon-optimized at its N-terminus; this was derived from construct b by replacing the rare codons in the area 1-321 bp without altering amino acid sequence. The N-terminal codon-optimized VP1 gene, opt-N, was fused with C-terminal domain of VP1 gene (VP1 C-term) by overlapping PCR, and then cloned into pGEX-4T-1. (B) Sequence comparison between the WT VP1 and Opt VP1 gene. The nucleotide sequences were compared between the original VP1 gene (WT VP1) and the sequence of codon-optimized VP1 gene (Opt VP1) over the N-terminal region. An asterisk ( * ) represents the fact that the aligned nucleotides are identical.

    ALS-FTLD-associated SQSTM1 mutations impact on the recognition of LC3B (SQSTM1 L341V ) or ubiquitin (SQSTM1 G425R ) in vitro. Mutations as indicated (or wild type, WT) were introduced into the full-length GST-SQSTM1 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.
