Abstract
A cell-free method for translation and assembly of viral capsid and capsid intermediates is disclosed. Also disclosed are novel capsid assembly intermediates and novel host proteins which bind to such assembly intermediates. The invention also includes a screening method for compounds that alter viral capsid assembly, and a method of treating viral infection using compounds which inhibit the capsid assembly pathway.
Claims8
A method for identifying a compound that interferes with capsid assembly of a virus, said method comprising:
- expressing at least one conformer of a protein required for said capsid assembly in the presence of a test compound, wherein said expressing is in a cell free translation system programmed with nucleic acid encoding said at least one conformer of such protein, and wherein said cell free translation system produces fully completed capsids in the absence of said test compound;
- and
- determining whether there has been a decrease in production of said capsids in the presence of said compound relative to the production of said capsids in the absence of said compound.
