Long Terminal Repeats (LTRs) - Encyclopedia of GeneticsELSEVIEREncyclopedia of Genetics
Long terminal repeats (LTRs) are DNA sequences flanking the proviral genes of retroviruses. These direct repeats are created from the viral RNA during the process of reverse transcription and contain sequence information from the 5′ and the 3′ end of the RNA. The LTRs help order the ...
Chicken syncytial viruses induce bursal lymphomas by integrating into the c-myc locus and activating myc expression by 3' long terminal repeat (LTR) promoter insertion. In contrast to wild-type proviruses, in which transcription initiates predominantly in the 5'LTR, these myc-associated proviruses ...

Its long-terminal repeats (LTRs) are unusually long (1,755 bp) compared with those of other retrotransposons. Sequence analysis revealed that they differ from each other by only six point mutations. They contain a few tandem direct repeats, which could be explained by slippage mechanisms during ...
The LTRs are identical and exhibit the following features: a terminal inverted 6-bp repeat, a Goldberg–Hogness (TATAAA) sequence, sequences which have been implicated in polyadenylation and the termination of transcription, and an open reading frame. The open reading frame of the R-LTR starts...
even those transposons flanked bydirect repeatssuch as LTRs are also flanked by short inverted repeats. That is, each LTR itself contains aterminal inverted repeat sequence– in the case ofTy1this sequence is TG … CA. Inverted repeat sequences are also known as palindromes. However, palindromes...
A human endogenous long terminal repeat provides a polyadenylation signal to a novel, alternatively spliced transcript in normal placenta We have been investigating the impact that the long terminal repeats (LTRs) of the RTVL-H family of human endogenous retroviral-like elements may have on t......
ISelements in bacteria carry perfect or nearly perfect inverted repeats of about 10–40 bp. These terminal repeats are believed to serve as recognition sequences for the transpositionenzymes(transposases) in their role of fusing the ends of the element with the target DNA. LTRs provide a ...
The HERV-H family of endogenous retrovirus-like elements is widely distributed in the human genome, with about 1,000 full-length elements and a similar number of solitary long terminal repeats (LTRs). HERV-H LTRs have been shown to direct the transcription of both HERV-H-encoded and adjacent...
