Ovine herpesvirus-2 (OvHV-2), a member of the gammaherpesviruses (genus Rhadinovirus), asymptomatically infects its natural host, the sheep, but causes malignant catarrhal fever (MCF) in susceptible hosts, such as cattle, deer and pigs. A permissive cell culture system for virus replication has not been identified but viral DNA is present within lymphoblastoid cell lines (LCLs) established from...
Biologists require genetic as well as molecular tools to decipher genomic information and ultimately to understand gene function. The Berkeley Drosophila Genome Project is addressing these needs with a massive gene disruption project that uses individual, genetically engineered P transposable elements to target open reading frames throughout the Drosophila genome. DNA flanking the insertions is...
Open reading frame (ORF) E4 is a 353-base-pair ORF of bovine papillomavirus type 1. To determine the biological activities of this ORF in mouse C127 cells, we analyzed the effects of two constructed mutations which are predicted to prevent synthesis of ORF E4 proteins while leaving the amino acid sequence encoded by the overlapping ORF E2 unchanged. Neither mutation interfered with the abilitie...
The full complement of genes encoded by Orf virus (ORFV) is not yet known. A cDNA library was constructed using mRNA isolated 5 h post-infection from cells infected with ORFV in vitro and grown in the presence of cytosine arabinoside. Using 12 non-overlapping probes representing the entire genome of the Orf-11 strain of the virus, cDNA clones representing individual genes expressed early in inf...
Large collections of protein-encoding open reading frames (ORFs) established in a versatile recombination-based cloning system have been instrumental to study protein functions in high-throughput assays. Such 'ORFeome' resources have been developed for several organisms but in virology, plasmid collections covering a significant fraction of the virosphere are still needed. In this perspective, ...
The Borna disease virus (BDV) antigenome is comprised of five major open reading frames (ORFs). Products have been reported only for ORFs I, II, and III, encoding N (p40), P (p24/p23), and M (gp18), respectively. ORF IV predicts a 57-kDa protein with several potential glycosylation sites. Analysis of radiolabeled extracts from BDV-infected C6 cells and BHK-21 cells transfected with a Semliki Fo...
One of the most puzzling results from the complete genome sequence of the methanogenic archaeon Methanococcus jannaschii was that the organism may have only one DNA polymerase gene. This is because no other DNA polymerase-like open reading frames (ORFs) were found besides one ORF having the typical alpha-like DNA polymerase (family B). Recently, we identified the genes of DNA polymerase II (the...
Recently, we identified and classified 926 human endogenous retrovirus H (HERV-H)-like proviruses in the human genome. In this paper, we used the information to, in silico, reconstruct a putative ancestral HERV-H. A calculated consensus sequence was nearly open in all genes. A few manual adjustments resulted in a putative 9-kb HERV-H provirus with open reading frames (ORFs) in gag, pro, pol, an...
We use a network of workstations to compute all pairwise alignments of the 500 bp upstream regions of 6,225 yeast ORFs (Open Reading Frames). We correlate the alignments with DNA microarray expression data f~om budding yeast cells over an oxidative stress time course. We confirm on a genomic scale that, in general, genes with extremely similar upstream regions have similar activity levels, even...
