Structure, expression and phylogenetic analysis of the glycoprotein gene of Cocal virus.
A cDNA copy of the mRNA of the glycoprotein G of Cocal virus, a rhabdovirus, has been cloned, sequenced and expressed in mammalian cells. The deduced amino acid sequence shows a typical transmembrane glycoprotein, 512 amino acids in length, containing two potential N-linked glycosylation sites. The amino acid sequence showed a high degree of identity with that of the prototype vesicular stomatitis virus serotype Indiana [VSV (IND)] G protein. In addition, phylogenetic analysis of amino acid sequence differences among the G proteins of vesiculoviruses indicated that Cocal virus represents a distinct lineage within the VSV (IND) serotype. Expression of the cloned Cocal G gene in mammalian cells produced a glycoprotein of mol.wt 71000 which was not palmitylated but induced cell fusion at acid pH.
