|Further information:||The plasmid was constructed by ligating the three following fragments: 1) the 4767 bp BglII/NotI fragment from pCAGGS-E-hABIN-1 2) a 226 bp NotI fragment of pFlag-hMKP-1 and 3) the 901 bp NotI/BglII fragment from pFlag-hMKP-1.
As compared to the wild type human DUSP1 coding sequence, codon 142 (CCC, proline) was replaced by a histidine (CAC) codon, resulting in the loss of an AvaI site and codon 360 (CCC, proline) was replaced by an arginine (CGC) codon. Additionally, the coding sequence includes the following silent nucleotide substitutions: C600A, A780G and G933A. Numbering includes the starting codon, which is absent in this plasmid.
The plasmid is useful for highly efficient expression of the fusion gene under the control of the AG promoter 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/tac/trc/N25/O2 promoter it may be advisable to use lacIq strains in order to prevent fortuitous expression of a possibly noxious polypeptide.
Other name of the plasmid is pCAGGS-E-hMKP1.
