Abstract
The nucleotide sequence of the mRNA encoding the glycoprotein of infectious hematopoietic necrosis virus was determined from a cDNA clone containing the entire coding region. The G-protein cDNA is 1,609 nucleotides long (excluding the polyadenylic acid) and encodes a protein of 508 amino acids. The predicted amino acid sequence was compared with that of the glycoprotein of the Indiana and New Jersey serotypes of vesicular stomatitis virus and with the glycoprotein of rabies virus, using a computer program which determined optimal alignment. An amino acid identity of approximately 20% was found between infectious hematopoietic necrosis virus and the two vesicular stomatitis virus serotypes and between infectious hematopoietic necrosis virus and rabies virus. The positions and sizes of the signal sequence and transmembrane domain and the possible glycosylation sites were determined.
