Abstract
In vitro translation of mRNA from cells infected with the autonomous parvovirus MVM yields four major virally coded proteins. Two of these proteins are indistinguishable both antigenically and by peptide map analysis from the viral capsid polypeptides VP-1 and VP-2. The other two proteins, designated NS-1 and NS-2, are not related to the capsid polypeptides but are recognized by sera from animals infected with different autonomous parvovirus serotypes. The NS-1 protein made in vitro comigrates with VP-1 (MW approximately 83,000), while the NS-2 polypeptide has an apparent molecular weight of 24,000. The transcript for the NS-1 polypeptide was mapped to a block of open reading frame located in the major intron of the left-hand transcription unit in the MVM genome.
