The complete nucleotide sequences of the vesicular stomatitis virus mRNA's encoding the glycoprotein (G) and the matrix protein (M) have been determined from cDNA clones that contain the complete coding sequences from each mRNA. The G protein mRNA is 1,665 nucleotides long, excluding polyadenylic acid, and encodes a protein of 511 amino acids including a signal peptide of 16 amino acids. G protein contains two large hydrophobic domains, one in the signal peptide and the other in the transmembrane segment near the COOH terminus. Two sites of glycosylation are predicted at amino acid residues 178 and 335. The close correspondence of the positions of these sites with the reported timing of the addition of the two oligosaccharides during synthesis of G suggests that glycosylation occurs as soon as the appropriate asparagine residues traverse the membrane of the rough endoplasmic reticulum. The mRNA encoding the vesicular stomatitis virus M protein is 831 nucleotides long, excluding polyadenylic acid, and encodes a protein of 229 amino acids. The predicted M protein sequence does not contain any long hydrophobic or nonpolar domains that might promote membrane association. The protein is rich in basic amino acids and contains a highly basic amino terminal domain. Details of construction of the nearly full-length cDNA clones are presented.
