Vesicular stomatitis virus N and NS proteins form multiple complexes.

The vesicular stomatitis virus nucleocapsid protein, N, associated specifically with the viral phosphoprotein, NS, in an in vitro system which supported vesicular stomatitis virus RNA replication. Essentially all the N protein was found complexed with NS. In addition, multiple forms of the N-NS complex were detected which differed in their sedimentation properties and ratios of N to NS.
