title: A ninth unique influenza virus-coded polypeptide.
abstract: A polypeptide with a molecular mass of ca. 11 000 has been found in various cell types infected with several strains of influenza A and B viruses. Differences have been found in the electrophoretic mobility of this polypeptide in cells infected with different strains, suggesting that it is virus coded. Peptide mapping studies have shown that this polypeptide is distinct from the eight defined influenza virus gene products. A fraction containing a virus-specific mRNA with an estimated size of ca. 300-400 nucleotides has been obtained. Schemes for the synthesis of this mRNA are discussed.
