Abstract:
:Region 1 DNA sequences (map positions 0 to 11% on the linear adenovirus 2 genome) are expressed both early and late in lytic infection and are required for transformation by the virus. During productive infection six distinct cytoplasmic RNAs are synthesized from this region. These RNAs comprise two families, each consisting of three size classes that share 3' sequences. Region 1 RNA's were purified by hybridization selection, using restriction fragments bound to nitrocellulose membranes, and by size fractionation. The isolated RNAs were then translated in cell-free systems derived from wheat germ and rabbit reticulocytes. The family of RNAs specified by 0 to 4.4 sequences includes two RNAs, which are 12S and 13S in size. These RNAs were partially separated by molecular weight and translated. The 13S RNA produced 53,000-dalton (53K) and 41K peptides, and the 12S RNA synthesized 47K and 35K products. The family of RNAs mapping from 4.4 to 11.0 encodes three separate polypeptides, each of which can be assigned to a specific RNA. A 12K product that comigrates with structural polypeptide IX is synthesized from the 9S RNA as previously reported (U. Pettersson and M. B. Mathews, Cell 12:741-750, 1977). The 13S RNA encodes a 15K polypeptide that corresponds to a 15K polypeptide in infected cell extracts. The 22s RNA encodes a 52K protein distinct from the 0 to 4.4 polypeptides.
