Cloned DNA: Human polypyrimidine tract binding protein 1 cDNA (PTBP1, HNRNP-I, HNRPI, pPTB, PTB-1, PTB2, PTB3, PTB4, GeneID 5725); fragment
Promoter: Chicken β-actin/rabbit β-globin hybrid promoter (AG)
Human cytomegalovirus immediate early promoter (CMV-IE); enhancer only
Escherichia coli lac operon promoter
binding site:
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: pCAGGS; pCAGGS-E-hPTB
Further information: The plasmid was constructed as follows: human ΔPTB was amplified by PCR on pCAGGS-E-hPTB and cloned as an EcoRI/BglII fragment in the EcoRI/BglII opened pCAGGS vector.
pCAGGS-deltaPTB is useful for highly efficient expression of human ΔPTB under the control of the AG promoter and the human CMV-IE enhancer in various mammalian cells.
The ΔPTB fragment contains the first two of the four RNA recognition motifs (RRM).
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 LT726973.1.
The nucleotide sequence of the human PTBP1 cDNA corresponds with the Genbank Nucleotide Sequence Database accession number NM_002819.4.
Name mentioned in Schepens et al. (2005) is pcΔPTB.
