|Further information:||The plasmid was constructed by inserting a 596 bp NcoI-SalI fragment, containing the mutated sequence of mBID, into the NcoI-SalI opened pAS2.1 vector. As a result, the mutated sequence of mBID is fused in phase to the N-terminal S. cerevisiae GALbd domain.
The mutated sequence of mBID was obtained by fusion PCR using pAS2mBID as template. As compared to the wt mBID cDNA, the glycine (G) codon at position 94 was replaced by a glutamic acid (E) codon.
pAS2.1 was derived from pAS2 by removing the Influenza HA epitope, encoding the haemagglutinin tagging peptide. Therefore, unlike pAS2mBIDG94E, pAS2.1mBIDG94E transformants lack aspecific β-galactosidase activity.
The S. cerevisiae GALbd is composed of the first 147 codons from GAL4, containing the nuclear localization signal.
The GALbd-mBIDG94E fusion protein can be used as a bait protein in two-hybrid screening.
pAS2.1mBIDG94E carries the S. cerevisiae tryptophan 1 coding sequence and the CYH2 sequence encoding ribosomal protein L29 for dominant cycloheximide sensitivity which facilitates the elimination of false positives.
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 pAS2.1 vector corresponds with the EMBL Nucleotide Sequence Database accession number U30497.1, corresponding to the Clontech website (version 05/01/1996).
The nucleotide sequence of the mBID cDNA corresponds with the Genbank accession number NM_007544.2 and adapted to the sequence analysis results of the Department of Biomedical Molecular Biology (Ghent University, Belgium). The following difference is observable: the nucleotide G at position 6023 is substituted by an A- residue, resulting in a Glu/Lys replacement for amino acid 14.
Other name of the plasmid is pAS2.1 mBid G94E.
