Polypeptides and cytomegalovirus (CMV) antigens that include at least two introduced amino acid mutations relative to the amino acid sequence of the wild-type HCMV glycoprotein B (gB). For example, polypeptides stabilized in a conformation alternative to the gB postfusion conformation. Compositions including the polypeptides and uses thereof.

Human cytomegalovirus gB polypeptide

The present invention comprises mutants of a wild-type cytomegalovirus (CMV) glycoprotein B (gB) protein that include at least two introduced amino acid mutations relative to the amino acid sequence of the wild-type HCMV glycoprotein B (gB), compositions including the mutants and uses thereof. In some embodiments, the mutant is stabilized in a conformation alternative to the gB postfusion conformation.

Human cytomegalovirus GB polypeptide

The present invention relates to polypeptides and cytomegalovirus (CMV) antigens that include at least one introduced amino acid mutation relative to the amino acid sequence of the wild-type HCMV glycoprotein B (gB). In some embodiments, the polypeptide is stabilized in a conformation alternative to the gB postfusion conformation. Also disclosed are compositions including the polypeptides and uses thereof.
