|Further information:||This plasmid was constructed by inserting a 3520 bp AseI fragment (filled in with Klenow DNA polymerase) from pPIC9-TSE, containing the prepro secretion signal sequence (ppMF) of the Saccharomyces cerevisiae α-mating factor 1 gene (MFα1) fused to the mature Trypanosoma cruzi trans-sialidase gene (TS) with C-terminal E-tag, in the MscI site of pCAGGS.
pCAGGS-prepro-TSE is useful for highly efficient expression of the fusion protein under the control of the chicken β-actin/rabbit β-globin hybrid promoter (AG) and the human CMV-IE enhancer in various mammalian cells.
The AG promoter sequence consists of the chicken β-actin promoter, the first exon and part of the first intron (that seems to have a strong enhancer-like activity) linked to a rabbit β-globin fragment, consisting of a 3' part of the second intron (inclusive a branch point which is required for normal splicing reactions) and a 5' part of the third exon.
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 LT727319.1.
Other name of the plasmid is pCAGGS-MFTSjE.
