FIELD: chemistry; biochemistry.
SUBSTANCE: invention relates to biotechnology, specifically to a method of identifying γ-secretase and its inhibitors and can be used in medicine when searching for active compounds for treating Alzheimer's disease. A genetic structure is formed, which codes fused protein, which contains a signal peptide and amino acid sequence GAIIGLMVGGVVIATVIVITLVML. In the obtained fused protein, except the GAIIGLMVGGVVIATVIVITLVML sequence, all sites acting as a signal for endo- or exocytosis, and/or protease splitting site are excluded.
EFFECT: invention allows for highly effective identification of γ-secretase or substances which inhibit its activity by reducing background signal and increasing specificity of the signal.
