- W1993684322 abstract "Early region 1B (E1B) of human adenoviruses encodes two major proteins. The 19-kDa polypeptide appears to prevent E1A-induced cytolysis and DNA degradation. The larger E1B product of approximately 55 kDa, which is essential for viral replication, plays a role in the accumulation and stability of viral mRNAs and the late shutoff of host metabolism. For serotype 12 (Ad12), this 482-residue (482R) protein is essential for viral DNA replication. In the present report we have used a series of mutants to examine the roles of Ad12 482R and the 19-kDa, 163R protein in the metabolism of early viral mRNAs. No specific effects on the accumulation of early (or late) mRNAs were detected with any of the mutants affecting 163R. With mutant dl42, which encodes an altered 482R product that lacks residues 114-155, both viral DNA replication and late viral protein synthesis were defective. Accumulation of E1A transcripts in the nucleus and cytoplasm resembled wt. The levels of mRNAs from early regions E1B, E2A and E3 at later times during infection were somewhat lower than those of wt, but this decrease may have been due to the absence of progeny viral DNA in dl42-infected cells. However, the accumulation of both E2B and E4 mRNAs at all times was severely reduced. These data suggested that the requirement of 482R for Ad12 DNA replication may be related to its specific role in the metabolism of E2B and E4 mRNAs that encode products necessary for viral DNA synthesis." @default.
