Further information: | The plasmid was constructed by inserting a KpnI-XbaI PCR fragment, amplified from a HepG2 cDNA library and containing the mutated, full-length hOMI coding sequence, between the KpnI and XbaI sites of pEF1/V5-HisA. Because of the presence of the hOMI termination codon, the C-terminal V5 epitope and histidine tag are not expressed. The full-length hOMI coding sequence includes an N-terminal mitochondrial targeting sequence. The serine (S) codon at position 306 of the hOMI coding sequence was replaced by an alanine (A) codon, creating an additional NaeI site. The human Omi/HtrA2 serine point mutant is no longer cytotoxic. 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. pEF1-hOMI-S306A is designed for high-level expression of mutated hOMI in mammalian cells. There is uncertainty about the presence of a second enhancer in the SV40 early promoter. The absence of a second enhancer in this promoter may cause bacterial leakage expression of the Tn5 neomycin resistance gene. This would cause transformed E. coli cells to be resistant to kanamycin, although growth should be reduced compared to growth on medium containing ampicillin. The nucleotide sequence of this plasmid corresponds with the EMBL Nucleotide Sequence Database accession number LT727110.1. The nucleotide sequence of the hOMI cDNA corresponds with the EMBL Nucleotide Sequence Database accession number AF141305.1. Other name of the plasmid is pEF1-hOmi/HtrA2-S306A. |
