cis-acting regulatory regions in the long terminal repeat of simian foamy virus type 1.
Simian foamy virus type 1 (SFV-1), a member of the Spumavirinae subfamily of retroviruses, encodes a transcriptional transactivator (taf) that strongly augments gene expression directed by the viral long terminal repeat (LTR) (A. Mergia, K. E. S. Shaw, E. Pratt-Lowe, P. A. Barry, and P. A. Luciw, J. Virol. 65:2903-2909, 1991). This report describes cis-acting regulatory elements in the LTR that...
متن کاملLocation of cis-acting regulatory sequences in the human T-cell leukemia virus type I long terminal repeat.
The location of cis-acting regulatory regions within the long terminal repeat (LTR) of the human T-cell leukemia virus type I (HTLV-1) was determined. The sequences present between nucleotides -350 and -55 (cap site +1) contain an enhancer element that is active in lymphoid and nonlymphoid cell lines. The sequences located near the "TATA" and RNA initiation sites contain a promoter, the activit...
متن کاملIn vivo protein binding and functional analysis of cis-acting elements in the U3 region of the bovine leukemia virus long terminal repeat.
Bovine leukemia virus (BLV) is a member of the human T-cell leukemia virus (HTLV)/BLV group of retroviruses. These viruses regulate their own transcription by producing Tax, a protein which activates the virus promoter region, the long terminal repeat (LTR). To explore the molecular mechanisms involved in the transactivation, we identified protein binding elements by in vivo footprinting and an...
متن کاملCis–Acting RNA Elements of Human Immunodeficiency Virus
The World Health Organization has indicated that effective control of the HIV/AIDS pandemic is the world’s most urgent public health challenge. The 2009 UNAIDS Global Facts and Figures report estimated that almost 60 million people have been infected with the virus and that 25 million AIDS-related deaths have occurred since the pandemic began in the early 1980s. In 2008, there were approximatel...
متن کاملCis- and trans-regulation of feline immunodeficiency virus: identification of functional binding sites in the long terminal repeat.
Nuclear protein binding sites in the long terminal repeat (LTR) of feline immunodeficiency virus (FIV) were identified by the method of DNase I footprinting. Using nuclear protein extracts from a feline T lymphoma cell line, several discrete footprints were generated upstream of the transcriptional initiation site (-50 to -150). The specificity of protein binding was examined by competition wit...
