|Further information:||The plasmid was constructed by ligating the three following fragments: 1) the 2240 bp KpnI-XhoI digested PCR fragment, containing the mutated hIKKα coding sequence; 2) the 2473 bp KpnI-FspI fragment from pCAGGS-FLAGmA20; 3) the 2369 bp XhoI-FspI-ApaI fragment from pCAGGS.
As compared to the wt hIKKα cDNA, the tryptophan (W) codon at position 740 was replaced by an alanine (A) codon, creating an additional PvuII site. Consequently, the mutated hIKKα will not bind to NEMO.
pCAGGS-Flag-IKKalpha-W740A is useful for highly efficient expression of hIKKα-W740A under the control of the AG promoter and the human CMV-IE enhancer in various mammalian cells.
The nucleotide sequence of this plasmid corresponds with the EMBL Nucleotide Sequence Database accession number LT726918.1.
The nucleotide sequence of the hIKKα cDNA corresponds with the Genbank accession number NM_001278.3.
Other name of the plasmid is pCAGGS-Flag-IKKα-W740A.

|Authenticity test:||Restriction enzyme pattern analysed at GeneCorner: Alw44I, ApaI/PvuII, KpnI, NcoI/NheI, NotI/XhoI and PvuI/XbaI.
As compared to the compiled nucleotide sequence, the restriction site analysis pattern revealed that ApaI only cuts twice instead of three times. The ApaI site at position 5860 could not be experimentally confirmed.
|History of deposit:||This plasmid was deposited by Dr K. Heyninck(1) (2) and Prof. Dr R. Beyaert(1) (2). It was constructed by M. Kreike(1) (2).
