Further information: The plasmid was constructed by inserting a 1386 bp NdeI-Sfil PCR fragment, containing the mutated, full-length hOMI coding sequence, into the NdeI-SfiI opened pAS2 vector. As a result, the mutated hOMI coding sequence is fused in phase to the N-terminal HA epitope and the S. cerevisiae GALbd domain.
The full-length hOMI coding sequence includes an N-terminal mitochondrial targeting sequence.
The serine (S) codon at position 306 of the hOMI coding sequence was replaced by an alanine (A) codon, creating an additional NaeI site.
The human Omi/HtrA2 serine point mutant is no longer cytotoxic.
The S. cerevisiae GALbd is composed of the first 147 codons from GAL4, containing the nuclear localization signal.
The GALbd-HA-hOMI-S306A fusion protein can be used as a bait protein in two-hybrid screening.
pAS2-hOMI-S306A carries the S. cerevisiae tryptophan 1 coding sequence (TRP1) 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 this plasmid corresponds with the EMBL Nucleotide Sequence Database accession number LT727107.1.
The nucleotide sequence of the pAS2 vector corresponds with the EMBL Nucleotide Sequence Database accession number U30496.1, but adapted as follows: 1) the 'N' nucleotide was removed, restoring the coding sequence of cycloheximide; 2) the sequence GATTTC between GALbd and the HA epitope was replaced by GAATTC, an EcoRI site that has been experimentally confirmed in pAS2; 3) the sequence TTCGAA (Csp45I site) in the ADH1 promoter was replaced by TCGAAG, eliminating the Csp45I site that could not be experimentally confirmed in pAS2.
The nucleotide sequence of the hOMI cDNA corresponds with the EMBL Nucleotide Sequence Database accession number AF141305.1.
