Restriction endonuclease mapping of the frog virus 3 genome
Virology, 1983A physical map for the frog virus 3 (FV 3) genome was constructed after digestion with the following restriction endonucleases: EcoRI, HindIII, KpnI, and XbaI. Mapping of the DNA was accomplished by partial digestion and recutting, double-digestion, and Southern blot hybridization with deduction of overlaps. Although the virion DNA is physically linear,

The inhibition of vesicular stomatitis virus protein synthesis by frog virus 3
Virology, 1979Abstract Heat-inactivated frog virus 3 (ΔFV 3) inhibited the synthesis of vesicular stomatitis virus (VSV) proteins in BHK cells by 40 to 60%. This inhibition was apparently a direct effect on translation because (i) inhibition occurred throughout the growth cycle of VSV and (ii) it did not depend on the ability of ΔFV 3 to inhibit transcription. The

Transcriptional Regulation of Frog Virus 3
1989Transcriptional regulation of eukaryotic promoters is now thought to be mediated by the interaction of specific trans— acting factors with cis-regulatory DNA sequences and RNA poly-merase II (Kingston et al., 1985). Large DNA viruses such as the iridovirus frog virus 3 (FV3) provide an excellent model system for the study of such regulatory processes ...

Localization of some frog virus 3 structural polypeptides
Virology, 1982Abstract The localization of several frog virus 3 structural polypeptides has been established by stripping the different layers of the virion with controlled degradations using Brij, NP 40, and Pronase. The degradation products were further separated on sucrose gradients and characterized by electron microscopy and SDS-gel electrophoresis.

The organization of frog virus 3 as revealed by freeze-etching
Virology, 1984A variety of freeze-fracture techniques has been employed in this study with the aim of dissecting the frog virus 3 virion and obtaining further information about its architecture. The icosahedral capsid has a skew symmetry with a triangulation number of 133 or 147. The capsomers are closely packed with a center-to-center spacing of 72 A.

Virology, 1979
Abstract A ts mutant (ts 9467) of frog virus 3 (FV3) does not synthesize late viral RNAs or proteins, although it does synthesize viral DNA. We have analyzed by polyacrylamide gel electrophoresis the RNAs and proteins produced in ts 9467-infected cells to determine the requirements for turning on late transcription. The electrophoretic pattern of the

Macromolecular Synthesis in Cells Infected by Frog Virus 3
1985The best studied member of the Iridoviridae is frog virus 3 (FV3), isolated by Granoff et al. (1966) from a renal adenocarcinoma of the leopard frog, Rana pipiens. Similar isolates were made from normal frog kidney and liver (FV1, FY 2, FV5–FY24), but FV3 was chosen for further investigation because of its presence in the tumor.

Instability of Frog Virus 3 mRNA in Productively Infected Cells
Virology, 1994Cloned DNA restriction fragments encoding representative frog virus 3 messages were used as probes to assess the stability of viral transcripts in infected fathead minnow cells. Analysis of Northern blot hybridization profiles confirmed earlier findings and revealed that in infected cells the steady-state level of representative frog virus 3 (FV3 ...

1989
Frog virus 3 (FV3) is a large icosahedral virus belonging to the Iridoviridae family. The genome is double—stranded, linear DNA with a molecular weight of 100 x 106 (Kelly and Avery, 1974; Murti et al., 1982). Among animal viruses, FV3 was the first demonstrated to contain a circularly permuted and terminally redundant genome (Goorha and Murti, 1982 ...

Transactivation of Methylated HIV-LTR by a Frog Virus 3 Protein
Virology, 1994DNA methylation has been implicated in the suppression of transcription of a large spectrum of eukaryotic genes. Frog virus 3 (FV3) contains genomic DNA that is the most extensively methylated of all known animal viruses. However, FV3 gene expression is tightly regulated in a sequential fashion in infected cells.
