HCV RNA-dependent RNA polymerase
View Patent ↗The present invention features NS5B polypeptides from different clinically important HCV genotypes. The polypeptides can be used individually, or as part of a panel of RNA-dependent RNA polymerases, to evaluate the effectiveness of a compound to inhibit NS5B activity.
1. A purified polypeptide comprising SEQ ID NO: 1.
2. The polypeptide of claim 1 , wherein said polypeptide consists of the amino acid sequence of SEQ ID NO: 1.
3. A recombinant nucleic acid comprising a nucleotide sequence encoding SEQ ID NO: 1.
4. The nucleic acid of claim 3 , wherein the nucleotide sequence encodes an amino acid sequence consisting of SEQ ID NO: 1.
5. The nucleic acid of claim 3 , wherein said nucleic acid is an expression vector.
6. The nucleic acid of claim 3 , wherein said nucleotide sequence is SEQ ID NO: 6.
7. A method of evaluating the ability of a compound to inhibit HCV RNA-dependent RNA polymerase comprising the step of measuring the ability of said compound to inhibit activity of one or more HCV RNA-dependent RNA polymerases, wherein at least one of the polymerases is SEQ ID NO: 1.
8. The method of claim 7 wherein activity of one HCV RNA-dependent RNA polymerase is measured and the polymerase is SEQ ID NO: 1.
