- the appearance time of the blue color can be very variable, from a few minutes to several hours. This test should always
- EXAMPLE 1 Construction of a vector allowing the expression of a fusion protein between the C-terminal part of the precursor of the amyloid peptide (CAPP) and the DNA binding domain of GAL4
- the 138 bpd DNA fragment corresponding to the last 46 amino acids of the APP was obtained by PCR from the Ogonucleotides (SEQ ID N ° 3 and N ° 4) which also allowed us to introduce the EcoRI and Dirty at the ends of the sequence.
- the PCR fragment was introduced between the EcoRI and SalI sites of the multisite for cloning the plasmid pGBTIO downstream of the sequence corresponding to GAL4DB to give the vector pGAL4DB-CAPP (FIG. 2).
- the construction was verified by DNA sequencing. This verification allowed us to show that this fragment did not present mutations generated during the PCR reaction and that it was fused in the same open reading phase as that of the fragment corresponding to GAL4DB.
- EXAMPLE 2 SCREENING OF THE BRAIN FUSION BANK.
- the screening of a fusion bank makes it possible to identify clones producing proteins fused to the transactivating domain of GAL4, which can interact with our protein of interest. This interaction makes it possible to reconstitute a transactivator which will then be capable of inducing the expression of the reporter genes His3 and LacZ in the YCM strain.
- a fusion library made from cDNA from the human brain As this library was supplied to us in the form of bacteria, the plasmid DNA of the library was first purified.
- the plasmid DNA from the brain cDNA library was extracted according to the Clontech protocol (see materials and methods, ⁇ 11). During this preparation, it was important to preserve the representativeness of the library, that is to say, to keep the number of independent plasmids which constitute it and which are 1.2.10 6 plasmids. In order to protect us from the loss of plasmids from the library during this preparation, the batch of plasmid DNA that we have assembled was obtained from a number of isolated bacterial colonies corresponding to slightly more than twice the representativeness of the bank, ie 4.10 6 colonies.
- each plasmid independent of the fusion library is present in at least one yeast at the same time as the plasmid GAL4DB-CAPP.
- a yeast transformation protocol giving an efficiency of 10 5 ceUules transformed per ⁇ g of DNA.
- This YCM-CAPP strain of His-, Lys-, Leu- phenotype was transformed with lOO ⁇ g of plasmid DNA from the fusion bank.
- EXAMPLE 3 ISOLATION OF BANK PLASMIDS
- the plasmid DNAs of the bacterial colonies obtained after transformation with yeast DNA extracts were analyzed by digestion with restriction enzymes and separation of the DNA fragments on agarose gel.
- the DNA of clone 3E is obtained from strains of the His + and ⁇ GAL + phenotype.
- EXAMPLE 4 DETERMINATION OF THE SEQUENCE OF THE INSERTS OF THE IDENTIFIED PLASMIDS.
- the sequencing was carried out using the oligonucleotide (SEQ ID No. 5) complementary to the GAL4TA region near the insertion site of the brain cDNA library, 52 bpd from the EcoRI site.
- the comparison of the 3 sequences with the sequences contained in the GENBank and EMBL (European Molecular Biology Lab) databases showed that the sequences of the cDNAs which were in the plasmids derived from strains 9A and 3H show 87% homology at the nucleic level with the mutant gene coding for the protein FE65, they are represented in SEQ ID No. 2, and that the sequence of the plasmid derived from the strain 7D has 60% homology with this same gene (see FIG. 3). Analysis of the sequence of the plasmids from strains 9A and 3H indicates that these contain two overlapping regions corresponding to the same mRNA. LIST OF SEQUENCES
