Human ubiquitin B cDNA (UBB, Ub, HEL-S-50, GeneID 7314); K27 mutated mature sequence|
FLAG epitope tag; N-terminal
|Promoter:||Chicken β-actin/rabbit β-globin hybrid promoter (AG)
Human cytomegalovirus immediate early promoter (CMV-IE); enhancer only
Escherichia coli lac operon promoter
|Terminator:||Rabbit β-globin polyadenylation signal (β-globin polyA)
Simian virus 40 polyadenylation signal (SV40 polyA)
|Selection marker:||Ampicillin (amp)|
|Replicon:||Escherichia coli plasmid pMB1 origin
Simian virus 40 bidirectional origin (SV40)
|Host range:||Escherichia coli
Mammalian cells; SV40 permissive cells
|Parental clone:||pET3E-His-AU1-hUb-K27; pCAGGS-FLAGmA20|
|Further information:||The plasmid was constructed as follows: 1) the human ubiquitin B mutated mature sequence was PCR amplified on the template pET3E-His-AU1-hUb-K27; 2) the KpnI and partially SalI digested amplicon was then inserted into the KpnI and SalI opened pCAGGS-FLAGmA20 plasmid.
The human ubiquitin B K27 cDNA only encodes the wild type lysine at position 27; the other six lysine codons at positions 6, 11, 29, 33, 48 and 63 are mutated to arginine codons.
pCAGGS-FLAG-hUb-K27 is useful for highly efficient expression of human Ub-K27 under the control of the AG promoter and the human CMV-IE enhancer in various mammalian cells.
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 LT726949.1.
The nucleotide sequence of the human Ub insert, which was the result of the sequence analysis at BCCM/GeneCorner, differs from the nucleotide sequence obtained from the EMBL Nucleotide Sequence Database accession number BT020104.1 in some silent mutations next to the 6 K->R mutations.
