|Further information:||The plasmid was constructed by inserting a 1136 bp NotI-XhoI PCR fragment, containing the codons 1 up to and including 375 of the mutated human A20-binding inhibitor of NF-κB activation 1 (hABIN-1) coding sequence, into the NotI-XhoI opened pCAGGS-E-hABIN1-P299A vector.
As compared to the wt hABIN-1 cDNA, the valine (V) codon at position 277 is replaced by an alanine (A) codon creating an additional MspA1I site, the proline (P) codon at position 299 is also replaced by an alanine (A) codon resulting in the loss of an AvaI site and the isoleucine (I) codon at position 9 contains a silent mutation (atc -> att) resulting in the loss of a DpnI and a Sau3AI site.
pCAGGS-E-hABIN1-N is useful for highly efficient expression of the mutated N-terminal fragment of hABIN-1, fused in phase to the N-terminal E-tag, 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 the hABIN-1 cDNA was obtained from Genbank (Accession number NM_006058.2).
