Cloned DNA: -
Promoter: Mouse metallothionein 1 promoter (Mt1)
Herpes simplex virus (HSV) thymidine kinase promoter (TK)
binding site:
Terminator: Herpes simplex virus (HSV) thymidine kinase polyadenylation signal (TK polyA)
Rabbit β-globin polyadenylation signal (β-globin polyA)
Selection marker: Ampicillin (amp)
Neomycin (neo; G418; kanamycin (kan))
Replicon: Escherichia coli plasmid pMB1 origin
Bovine papilloma virus origin (BPV)
Host range: Escherichia coli
Mammalian cells; e.g. NIH3T3, FR3T3, C127
Parental clone: BMTNeo
Further information: pBMGNeo has the ability to replicate extrachromosomally in some mammalian cells (because of the 69% fragment of bovine papilloma virus) as well as in prokaryotic cells (due to the E. coli pMB1 origin of replication).
The bacterial gene for neomycin resistance is used as a dominant selectable marker: in bacteria, the expression of this gene is driven by its own promoter; in mammalian cells by the HSV-TK promoter.
The mouse Mt1 promoter controls the expression of inserted cDNA's in mammalian cells; this mouse Mt1 promoter can be induced by some kations such as Zn(2)(+) or Cd(2)(+).
The polyA signal and the 3' flanking region from the rabbit β-globin gene allow efficient processing and termination of transcription.
The fragment of the human genomic β-globin DNA carries an activity that enhances the ability of BPV vectors to replicate as episomes.
cDNA can be inserted into the SalI expression site as well as in the XhoI expression site. The majority of full-length cDNA's can be inserted since XhoI and SalI sites are rare in mammalian DNA.
Because of the presence of the second intron of the rabbit β-globin gene, cDNA inserts in the SalI site (located at 20 bp in front of the splice donor signal) are spliced in the 3' untranslated region and inserts in the XhoI site (located at 50 bp behind the splice acceptor signal) in the 5' untranslated region.
The nucleotide sequence of the plasmid was compiled based on the information in Karasuyama et al. (1988). However, we could not completely trace back the sequence, that thus contains some uncertainties. Consequently, there is also uncertainty as to the cutting frequency of the restriction enzymes, except for the sites that were analysed in the authenticity test.
The nucleotide sequence of the bovine papilloma virus corresponds with the EMBL Nucleotide Sequence Database accession number X02346.1.
Name mentioned in Karasuyama et al. (1988) is BMGNeo.
EMBL Accession number: X02346.1, view at EMBL, GenBank, DDBJ
Latest sequence update: 09/09/2008
Authenticity test: Restriction enzyme pattern analysed at GeneCorner: BamHI, HindII/HindIII, NotI, NotI/XbaI, SalI, XbaI and XhoI.

This plasmid has also been fully sequenced but the NGS sequence data still need to be implemented.
