|Parental clone:||pET3E-His-AU1-hUb-K33; pCD-F-bio-MK-N149|
|Further information:||The plasmid was constructed by PCR amplifying the human UBB coding sequence from pET3E-His-AU1-hUb-K33 and ligating it as a BamHI/ApaI fragment into pCD-F-bio-MK-N149, replacing the human MALT1 coding sequence.
The human ubiquitin B K33 cDNA only encodes the wild type lysine at position 33; the other six lysine codons at positions 6, 11, 27, 29, 48 and 63 are mutated to arginine codons.
This plasmid is generated for high-affinity isolation of ubiquitinated proteins of a specific linkage. Biotinylation requires co-transfection of a mammalian expression vector with BirA. For even greater specificity, this plasmid can be combined with the corresponding His-tagged ubiquitin for 2D (first His-purification, then biotin precipitation) isolation of ubiquitinated proteins under denaturing conditions, for example for proteomic studies.
The nucleotide sequence of the wild type human UBB coding sequence corresponds with the EMBL Nucleotide Sequence Database accession number BT020104.1, except for some silent mutations.
Other name of the plasmid is pCD-F-bio-Ub-K33.
