|Further information:||This plasmid was constructed as follows: i) the XbaI-StuI fragment of pSCGAL1MF3, containing the prepro secretion signal sequence (ppMF) of the Saccharomyces cerevisiae α-mating factor 1 gene (MFα1), was ligated to the XbaI-Eco47III vector fragment of pUChGNTI1; ii) this intermediate construction was then digested with HindIII and EcoRI, the sticky ends were filled in with Klenow DNA polymerase and EcoRI linkers (5'-CGGAATTCCG-3') were added; iii) finally, this EcoRI-EcoRI fragment was digested with XbaI and EcoRI and the resulting XbaI-EcoRI fragment was inserted into the XbaI-EcoRI digested pCAGGS vector.
This expression plasmid carries the ppMF sequence of the S. cerevisiae MFα1 gene fused to the mature sequence of the human gene encoding N-acetylglucosaminyltransferase I, cloned in the sense orientation relative to the chicken β-actin/rabbit β-globin hybrid promoter (AG).
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 LT727444.1.
The nucleotide sequence of the human GlcNAc-TI cDNA corresponds with the Genbank accession number M55621.1.
