Cloned DNA: Mouse tumor necrosis factor, alpha-induced protein 3 cDNA (Tnfaip3, A20, Tnfip3, GeneID 21929); fragment
Promoter: Phage T7 gene 10 promoter (T7g10)
Phage T3 promoter
Escherichia coli lac operon promoter
binding site:
Ribosome binding site (RBS) of the Escherichia coli lac Z gene (lacZ)
Terminator: -
Selection marker: Ampicillin (amp)
Replicon: Escherichia coli plasmid pMB1 origin
Phage f1 origin
Host range: Escherichia coli; use strains expressing the lacZ ω fragment (lacZΔM15) for screening
Parental clone: pBluescriptIIKS-
Further information: pBlue-mA20f3 was constructed as follows: 1) pBluescriptIIKS- was digested with BamHI, filled in with Klenow DNA polymerase and religated. 2) a 1116 bp KpnI-SalI PCR fragment, containing codons 1 up to and including 366 of the mouse zinc finger protein A20 coding sequence (mA20), was then inserted between the SalI and KpnI sites.
pBlue-mA20f3 contains the T7 and T3 RNA polymerase promoters for efficient in vitro RNA synthesis of the coding or non-coding DNA strand.
This plasmid also contains the replication origin of the single-stranded DNA phage f1 (clockwise orientated), so that it can be rapidly switched between the plasmid and the phage mode (ssDNA) of replication. The latter requires infection with a helper phage, e.g. M13KO7.
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.
The nucleotide sequence of this plasmid corresponds with the EMBL Nucleotide Sequence Database accession number LT727290.1.
The nucleotide sequence of pBluescriptIIKS- corresponds with the EMBL Nucleotide Sequence Database accession number X52329.1.
The nucleotide sequence of the mA20 cDNA corresponds with the EMBL Nucleotide Sequence Database accession number U19463.1 and adapted to the sequence analysis results of the Department of Biomedical Molecular Biology (Ghent University, Belgium). The following difference is observable: the nucleotide T at position 2096 is substituted by a C- residue, resulting in a Leu/Pro replacement.
Other names of the plasmid are pBluescript-mA20(1-366) and pB-001-006#1.
