Peptide Synthesis> | Benzoyl-norleucine-lysine-lysine-arginine 7-amido-4-methylcou-marin (Bz-Nle-Lys-Lys-Arg-AMC; Genscript) was used as substrate to measure protease activity and the efficacy of different NS3 inhibitors. | Get A Quote |
Zika virus (ZIKV) targets neural progenitor cells in the brain, attenuates cell proliferation, and leads to cell death. Here, we describe a role for the ZIKV protease NS2B-NS3 heterodimer in mediating neurotoxicity through cleavage of a host protein required for neurogenesis. Similar to ZIKV infection, NS2B-NS3 expression led to cytokinesis defects and cell death in a protease activity-dependent fashion. Among binding partners, NS2B-NS3 cleaved Septin-2, a cytoskeletal factor involved in cytokinesis. Cleavage of Septin-2 occurred at residue 306 and forced expression of a non-cleavable Septin-2 restored cytokinesis, suggesting a direct mechanism of ZIKV-induced neural toxicity.
