|Further information:||The plasmid was constructed as follows: 1) the mitochondrial targeting sequence (MTS) of the human manganese superoxide dismutase gene (hMnSOD) was amplified by PCR on pCAGGShMnSOD; 2) the hybrid rat/human catalase mature sequence was amplified by PCR on pCMVrhCAT (a TGA termination codon was introduced, 48 nucleotides of the coding sequence of hCAT are missing); 3) the MTS sequence and the hybrid catalase sequence were fused by PCR; 4) the fusion gene was inserted as an EcoRI/MstII(SauI) fragment between the EcoRI and MstII(SauI) sites of pCAGGS.
pCAGGSMtCAT is useful for highly efficient expression of MTS-rhCAT under the control of the chicken β-actin/rabbit β-globin hybrid promoter (AG) and the human CMV- IE enhancer in various mammalian cells.
The AG promoter sequence consists of the chicken β-actin promoter, the first exon and part of the first intron (that seems to have a strong enhancer-like activity) linked to a rabbit β-globin fragment, consisting of a 3' part of the second intron (inclusive a branch point which is required for normal splicing reactions) and a 5' part of the third exon.
The catalase fragment from the ATG to the PvuII site originates from rat, the fragment from the PvuII site to the termination codon originates from human.
When cloning a fragment downstream from the lac promoter it may be advisable to use lacI(q) strains in order to prevent fortuitous expression of a possibly noxious polypeptide.
he nucleotide sequence of the human MnSOD cDNA corresponds with the EMBL Nucleotide Sequence Database accession number Y00472.1, with minor corrections in the 5' UTR and with the Ala->Val polymorphism in the MTS. The differences were confirmed by sequence analysis at the Department of Biomedical Molecular Biology (Ghent University, Belgium).
Other name of the plasmid is pCAGGS/Mt-catalase.
