13. “Hidden” dUTPase Sequence in Human Immunodeficiency Virus Type 1 gp120
A coding region homologous to the sequence for essential eukaryotic enzyme dUTPase has been identified in different genomic regions of several viral lineages. Unlike the nonprimate lentiviruses (caprine arthritis- encephalitis virus, equine infectious anemia virus, feline immunodeficiency virus, and visna virus), where dUTPase is integrated into the pol codi

14. Selection against CpG dinucleotides in lentiviral genes: a possible role of methylation in regulation of viral expression.
Extremely low frequencies of CpG dinucleotides are found in the genomes of the lentivirus subfamily of retroviruses, including the human, simian and feline immunodeficiency viruses (HIV1, HIV2, SIV, and FIV, respectively), equine infectious anemia virus (EIAV), and the ovine lentivirus, Visna. The occurrence of CpG dinucleotides is greater in the 2-3 (NCG) t

15. Characterization of a retravirus isolated from squirrel monkeys.
A new retravirus (SMRV) isolated from a squirrel monkey, Saimiri sciureus, has an Mg2+-dependen reverse transcriptase and a buoyant density of 1.17 g/cm3 in sucrose and 1.21 g/cm3 in cesium chloride, similar to the mouse mammary tumor virus and the Mason-Pfizer monkey virus. The polypeptide patter of SMRV as determined by sodium dodecyl sulfate-polyacrylamid

16. Envelope Glycoprotein Cytoplasmic Domains from Diverse Lentiviruses Interact with the Prenylated Rab Acceptor
Lentivirus envelope glycoproteins have unusually long cytoplasmic domains compared to those of other retroviruses. To identify cellular binding partners of the simian immunodeficiency virus (SIV) envelope transmembrane protein (gp41) cytoplasmic domain (CD), we performed a yeast two-hybrid screen of a phytohemagglutinin-activated human T-cell cDNA library wi

17. Initiation of (-) strand DNA synthesis from tRNA(3Lys) on lentiviral RNAs: implications of specific HIV-1 RNA-tRNA(3Lys) interactions inhibiting primer utilization by retroviral reverse transcriptases.
Initiation of minus (-) strand DNA synthesis was examined on templates containing R, U5, and primer-binding site regions of the human immunodeficiency virus type 1 (HIV-1), feline immunodeficiency virus (FIV), and equine infectious anemia virus (EIAV) genomic RNA. DNA synthesis was initiated from (i) an oligoribonucleotide complementary to the primer-binding

18. Important Role for the CA-NC Spacer Region in the Assembly of Bovine Immunodeficiency Virus Gag Protein
Lentiviral Gag proteins contain a short spacer sequence that separates the capsid (CA) from the downstream nucleocapsid (NC) domain. This short spacer has been shown to play an important role in the assembly of human immunodeficiency virus type 1 (HIV-1). We have now extended this finding to the CA-NC spacer motif within the Gag protein of bovine immunodefic

19. DNA Sequence Relationship of the Baboon Endogenous Virus Genome to the Genomes of Other Type C and Type D Retroviruses
Baboon endogenous virus (BaEV) is a type C retrovirus present in multiple proviral copies in the DNA of baboons. Although interspecies antigenic determinants present on reverse transcriptase and gag proteins are shared among all mammalian type C viruses, no nucleic acid homology between BaEV and other type C viruses (except RD-114) has been found in conventi
