    γ-Secretase is a protease complex embedded in the cell membrane, consisting of the catalytic presenilin subunits (PS1 or PS2) and three additional co-factors: nicastrin, Aph-1, and Pen2. It cleaves the transmembrane domains of type-I transmembrane proteins, such as the amyloid precursor protein (APP) and Notch. The cleavage of APP generates the amyloid β peptides (Aβ), which accumulate in patients with Alzheimer's disease. Despite significant research, the exact mechanism of this unique proteolysis, which occurs within the lipid bilayers, is still not fully understood. To study the enzymatic properties of γ-secretase, we have established a yeast reporter system using artificial γ-secretase substrates containing APP or Notch fragments fused to the transcriptional activator Gal4. The γ-secretase activity was evaluated by transcriptional activation of reporter genes upon Gal4 release from the membrane-bound substrates, as assessed by the growth of yeast or β-galactosidase activity. Furthermore, we have developed an in vitro assay to identify the different forms of Aβ produced from yeast microsomes. These yeast models provide a platform to screen mutations, genes, and compounds that affect γ-secretase function. By studying the loss of function properties of PS1 familial Alzheimer's disease (FAD) mutants, it is possible to screen for FAD suppressor mutations and γ-secretase modulators (GSMs), in addition to γ-secretase inhibitors (GSIs). In this report, we describe the genetic and biochemical methods used to study γ-secretase activity in the yeast system with the essential steps of the protocol for the video.

    The emergence of coronavirus disease 2019 (COVID-19) posed a major challenge to healthcare systems worldwide, especially as mutations in the culprit Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) complicated the development of vaccines and antiviral drugs. Therefore, the search for natural products with broad anti-SARS-CoV-2 capabilities is an important option for the prevention and treatment of similar infectious diseases. Lectins, which are widely recognized as antiviral agents, could contribute to the development of anti-SARS-CoV-2 drugs. This study evaluated the binding affinity of six lectins (including the cyanobacterial lectin from Microcystis viridis NIES-102 (MVL), and Jacalin, a lectin from the breadfruit, Artocarpus altilis) to the receptor binding domain (RBD) of the spike protein on the original (wild) SARS-CoV-2 and three of its mutants: Alpha, Delta, and Omicron. MVL and Jacalin showed distinct binding affinity to the RBDs of the four SARS-CoV-2 strains. The remaining four lectins (DB1, ConA, PHA-M and CSL3) showed no such binding affinity. Although the glycan specificities of MVL and Jacalin were different, they showed the same affinity for the spike protein RBDs of the four SARS-CoV-2 strains, in the order of effectiveness Alpha > Delta > original > Omicron. The verification of glycan-specific inhibition revealed that both lectins bind to RBDs by glycan-specific recognition, but, in addition, MVL binds to RBDs through protein-protein interactions.
