Long terminal repeat - Wikipedia
A long terminal repeat (LTR) is a pair of identical sequences of DNA, several hundred base pairs long, which occur in eukaryotic genomes on either end of a series of genes or pseudogenes that form a retrotransposon or an endogenous retrovirus or a retroviral provirus.
Long Terminal Repeat - an overview | ScienceDirect Topics
Long-terminal repeats. LTR is present on either side of the viral genome. It harbors cis-acting elements, which are required for RNA synthesis, and is the initiation site for transcription of the viral genome. LTR consists of three regions: U3 (unique, 3′ end), R (repeated), and U5 (unique, 5′ end). Various elements present in U3 help in ...
Long terminal repeats power evolution of genes and gene …
Retrotransposons often carry long terminal repeats (LTRs) for retrovirus-like reverse transcription and integration into the genome. We report an extraordinary impact of a group of LTRs from the mammalian endogenous retrovirus-related ERVL retrotransposon class on gene expression in the germline and beyond.

Long Terminal Repeat - an overview | ScienceDirect Topics
Long terminal repeats (LTRs) at the ends of mRNA initiate gene transcription and are bound by several transcription factors [55].
