Further information: The plasmid was constructed by blunt ligation of the Saccharomyces cerevisiae ADE2 gene under its own promoter into the EcoRV opened pAS2 vector.
pAS3 is designed to generate a fusion of the S. cerevisiae GALbd domain with a sequence encoding a target protein (bait fusion protein).
The GALbd is composed of the first 147 codons from GAL4, containing the nuclear localization signal, and is followed by the HA epitope sequence, a multicloning site and termination codons in all reading frames.
pAS3 is useful in a yeast three-hybrid approach. The ADE2 auxotrophic selection marker makes the system compatible with the existing yeast strains and libraries that are currently used in Gal4-based two- and three-hybrid systems and which make use of the TRP1, LEU2, HIS3 and URA3 selection markers.
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 this plasmid corresponds with the EMBL Nucleotide Sequence Database accession number LT727334.1.
The nucleotide sequence of the ADE2 cDNA corresponds with the Genbank accession number NC_001147.5.
