Norovirus virus-like particle (NoV VLP)

Norovirus virus-like particles are self-assembled structures composed primarily of the major capsid protein VP1 from noroviruses. These particles closely mimic the morphology and antigenicity of native noroviruses but lack viral genetic material, making them non-infectious. The VP1 protein forms icosahedral shells with T=3 symmetry, consisting of 180 copies arranged as 90 dimers. Each VP1 monomer has two domains: a shell domain that forms the structural core and a protruding domain involved in receptor binding, strain diversity, and immunogenicity. Virus-like particles are widely used in research to study immune responses to noroviruses, develop diagnostic assays, and serve as platforms for candidate vaccines because they present relevant epitopes without risk of causing disease. They do not function as receptors or enzymes themselves; rather, they are tools that simulate the external features of actual viruses. Note on correctness: "Norovirus virus-like particles" is not a canonical therapeutic target such as a receptor or enzyme. Instead, it refers to recombinant assemblies used mainly for research purposes—particularly vaccine development or serology—not direct drug targeting or modulation. Thus "is_target" should be set to false; "is_incorrect" should be true if you require only bona fide molecular targets like receptors or enzymes per your conventions above.
