Abstract
The present invention provides mutant RSV F molecules, such as those that can be, or are stabilized, in a pre-fusion conformation by the introduction of one or more DT cross-links. The present invention also provides methods of making such mutant RSV F molecules, compositions comprising such mutant RSV F molecules, and methods of use of such mutant RSV F molecules, for example in vaccination methods, therapeutic methods, and antibody production methods.
Claims20
A mutant RSV F molecule comprising:
- (a) an F2 polypeptide comprising amino acid residues 26-109 of SEQ ID NO 81, and (b) an F1 polypeptide comprising amino acid residues 137-513 of SEQ ID NO 81;
- wherein the F2 polypeptide is linked to the F1 polypeptide by a disulfide bond.
A soluble, mature trimeric RSVF molecule consisting of three monomers, wherein each monomer comprises (a) an F2 polypeptide comprising amino acid residues 26-109 of SEQ ID NO 81, and (b) an F1 polypeptide comprising amino acid residues 137-513 of SEQ ID NO. 81, and (c) a heterologous trimerization domain, wherein the F2 polypeptide is linked to the F1 polypeptide by a disulfide bond.
