    Description: Viruses have always been classified according to whether their genome is composed of DNA or RNA. That may be set to change with the discovery that human cytomegalovirus has both a DNA genome and four mRNA transcripts that are produced before the DNA genome is transcribed after infection of the host cell (Bresnahan and Shenk). As Roizman points out in a lively Perspective, finding out what the proteins encoded by these four mRNAs do, and whether other DNA viruses show this sneaky partnering of DNA and RNA, will keep virologists busy for many years to come.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Roizman, B -- New York, N.Y. -- Science. 2000 Jun 30;288(5475):2327-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Marjorie Kovler Viral Oncology Laboratories, University of Chicago, 910 East 58th Street, Chicago, IL 60637, USA. bernard@kovler.uchicago.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10917831" target="_blank"〉PubMed〈/a〉

    Description: The gene designated gamma 134.5 maps in the inverted repeats flanking the long unique sequence of herpes simplex virus-1 (HSV-1) DNA, and therefore it is present in two copies per genome. This gene is not essential for viral growth in cell culture. Four recombinant viruses were genetically engineered to test the function of this gene. These were (i) a virus from which both copies of the gene were deleted, (ii) a virus containing a stop codon in both copies of the gene, (iii) a virus containing after the first codon an insert encoding a 16-amino acid epitope known to react with a specific monoclonal antibody, and (iv) a virus in which the deleted sequences were restored. The viruses from which the gene was deleted or which carried stop codons were avirulent on intracerebral inoculation of mice. The virus with the gene tagged by the sequence encoding the epitope was moderately virulent, whereas the restored virus reacquired the phenotype of the parent virus. Significant amounts of virus were recovered only from brains of animals inoculated with virulent viruses. Inasmuch as the product of the gamma 134.5 gene extended the host range of the virus by enabling it to replicate and destroy brain cells, it is a viral neurovirulence factor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chou, J -- Kern, E R -- Whitley, R J -- Roizman, B -- AI 1588-11/AI/NIAID NIH HHS/ -- AI 24009/AI/NIAID NIH HHS/ -- CA 47451/CA/NCI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1990 Nov 30;250(4985):1262-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Marjorie B.

    Description: The transition from the expression of alpha, the first set of five herpes simplex virus genes expressed after infection, to beta and gamma genes, expressed later in infection, requires the participation of infected cell protein 4 (alpha 4), the major viral regulatory protein. The alpha 4 protein is present in complexes formed by proteins extracted from infected cells and viral DNA fragments derived from promoter domains. This report shows that the alpha 4 protein forms specific complexes with DNA fragments derived from 5' transcribed noncoding domains of late (gamma 2) genes whose expression requires viral DNA synthesis as well as functional alpha 4 protein. Some of the DNA fragments to which alpha 4 binds do not contain homologs of the previously reported DNA binding site consensus sequence, suggesting that alpha 4 may recognize and interact with more than one type of DNA binding site. The alpha 4 proteins can bind to DNA directly. A posttranslationally modified form of the alpha 4 protein designated alpha 4c differs from the alpha 4a and alpha 4b forms with respect to its affinity for DNA fragments differing in the nucleotide sequences of the binding sites.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Michael, N -- Spector, D -- Mavromara-Nazos, P -- Kristie, T M -- Roizman, B -- AI124009/AI/NIAID NIH HHS/ -- CA08494/CA/NCI NIH HHS/ -- CA19264/CA/NCI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1988 Mar 25;239(4847):1531-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Marjorie B.

    Description: Viruses classified by immunologic criteria as equine herpesvirus 1 cause respiratory disease and abortion in horses. Restriction endonuclease analyses of the DNA's of viruses from animals with respiratory disease and from aborted fetuses show that the patterns for respiratory viruses, while similar to each other, are entirely different from the patterns for fetal viruses. It is therefore proposed that the DNA restriction endonuclease patterns of fetal and respiratory viruses analyzed in this study be designated as prototypic of equine herpesvirus 1 and 4, respectively.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Studdert, M J -- Simpson, T -- Roizman, B -- CA 08494/CA/NCI NIH HHS/ -- CA 09241/CA/NCI NIH HHS/ -- CA 19264/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1981 Oct 30;214(4520):562-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6270790" target="_blank"〉PubMed〈/a〉

    Description: The herpes simplex virus 1 genome consists of one long and one short stretch of unique sequences flanked by inverted repeat sequences. The nucleotide sequence and RNA map predict 12 open reading frames designated as US1 through US12 within the short stretch of unique sequences. This paper reports the construction of virus mutants from which US2, US3, or US4 had been deleted that are capable of growth in cell culture. One of the three deleted genes, US4, specifies the viral envelope glycoprotein G. Mutants with deletions in US1, US8, US9, US10, US11, and US12 have been previously reported. The nine genes deleted from this region form two clusters, US1 through US4 and US8 through US12, and encode at least two and possibly more structural proteins. The presence of so many genes dispensable for growth in cell culture suggests several hypotheses regarding their function and evolution.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Longnecker, R -- Roizman, B -- CA-08494/CA/NCI NIH HHS/ -- CA-19264/CA/NCI NIH HHS/ -- T32 PHS AI 07182/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1987 May 1;236(4801):573-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3033823" target="_blank"〉PubMed〈/a〉

    Description: Analyses of the function of specific genes and sequences of large DNA viruses such as herpesviruses and poxviruses present special problems because of the size of their genomes (120 to 250 kilobase pairs). Various methods for engineering site-specific insertions or deletions based on the use of selectable markers have been developed and applied for the elucidation of the function of specific DNA sequences, the identification of genes nonessential for virus growth in cell culture, and the expression of foreign genes. These methods should also make possible the construction of viral vectors capable of delivering genes specifying antigens for the prevention of infectious diseases in humans and animals.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Roizman, B -- Jenkins, F J -- CA08494/CA/NCI NIH HHS/ -- CA09241/CA/NCI NIH HHS/ -- CA19264/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1985 Sep 20;229(4719):1208-14.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2994215" target="_blank"〉PubMed〈/a〉
