Abstract:
The present invention is based upon the identification of human angiotensin-converting enzyme-2 (ACE-2) as a functional receptor for the SARS coronavirus. Transfection of cells with ACE-2 confers upon them the ability to support viral replication. In addition, assays performed using ACE-2 together with the S protein of the SARS virus or a fragment derived from the S protein can be used to identify inhibitors that block the interaction between virus and host cell.
Receptor Binding Peptides Derived From The Sars S Protein
The present invention is directed to peptides that bind to the cellular receptors for the SARS S protein. The invention also includes polynucleotides coding for these peptides and methods in which they can be used to block the binding of the S protein to receptor. The peptides can also be detectably labeled and used in assays for identifying cells that have receptors for the S protein, in vaccines and for identifying other agents that inhibit receptor binding.
