Trans-acting transcriptional regulation of human T-cell leukemia virus type III long terminal repeat.
Human T-cell leukemia virus type III (HTLV-III) was recently identified as the probable etiologic agent of the acquired immune deficiency syndrome (AIDS). Here it is shown that, in human T-cell lines infected with HTLV-III, gene expression directed by the long terminal repeat sequence of this virus is stimulated by more than two orders of magnitude compared to matched uninfected cells. The rate...
متن کاملA cyclic AMP-responsive DNA-binding protein (CREB2) is a cellular transactivator of the bovine leukemia virus long terminal repeat.
To gain insight into the cellular regulation of bovine leukemia virus (BLV) trans activation, a lambda-gt11 cDNA library was constructed with mRNA isolated from a BLV-induced tumor and the recombinant proteins were screened with an oligonucleotide corresponding to the tax activation-responsive element (TAR). Two clones (called TAR-binding protein) were isolated from 750,000 lambda-gt11 plaques....
متن کاملTranscription factor AP-4 participates in activation of bovine leukemia virus long terminal repeat by p34 Tax.
Three 21bp repeats can be found in the bovine leukemia virus long terminal repeat, which are crucial for the LTR directed gene expression by the trans activator protein Tax. Previous studies demonstrated that the major target of the Tax directed activation are the CRE-like elements in the center of these repeats. In this work we report that another motif of the 21bp repeats is also required for...
متن کاملNucleotide sequence analysis of the long terminal repeat of human T-cell leukemia virus type II.
The nucleotide sequence of the human T-cell leukemia virus type II (HTLV-II) long terminal repeat (LTR) and its surrounding regions were determined. Our results show the following structural features: (i) the LTR is 763 base pairs (bp) in length and consists of 314 +/- 1 bp of region U3, 248 +/- 1 bp of region R, and 201 bp of region U5; (ii) the terminal nucleotides in the LTR form an inverted...
متن کاملImportant role of the long terminal repeat of the helper Moloney murine leukemia virus in Abelson virus-induced lymphoma.
The helper virus has been shown to play a critical role in the development of lymphoma induced by the defective Abelson murine leukemia virus (A-MuLV). Indeed, A-MuLV pseudotyped with some viruses, such as the Moloney MuLV, has been shown to be highly lymphogenic, whereas A-MuLV pseudotyped with other viruses, such as the BALB/c endogenous N-tropic MuLV, has been shown to be devoid of lymphogen...
