Abstract
Saporin, a type I ribosome-inactivating protein from soapwort plant, is a potent protein synthesis inhibitor. Catalytically, saporin is a characteristic N-glycosidase, and it depurinates a specific adenine residue from a universally conserved loop of the major ribosomal RNA (rRNA) of eukaryotic cells. It is well-known that saporin induces apoptosis through different pathways, including ribotoxic stress response, cell signal transduction, genomic DNA fragmentation and RNA abasic lyase (RAlyase) activity, and NAD+ depletion by poly-(ADP)-ribose polymerase hyperactivation. Saporin's high enzymatic activity, high stability, and resistance to conjugation procedures make it a well-suited tool for immunotherapy approaches.In the present study, we focus on saporin-based targeted toxins that may be efficacious therapeutic agents for the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Our discussed points suggest that saporin may be a strategic molecule for therapeutic knockout treatments and a powerful candidate for novel drugs in the struggle against coronavirus 2019 (COVID-19).
