    摘要: Filovirus glycoprotein mutations that stabilize the trimeric form of the glycoprotein are provided. The Filovirus glycoproteins have certain amino acid substitutions at specified positions in the glycoprotein sequence. The Filovirus glycoproteins described herein have an improved percentage of trimer formation and/or an improved trimer yield as compared to a Filovirus glycoprotein that does not have one or more of the indicated amino acid substitutions. Also provided are nucleic acid molecules and vectors encoding the Filovirus glycoproteins, as well as compositions containing the Filovirus glycoproteins, nucleic acid, and vectors.
