Ltr

Ltr --> long-terminal repeat

(Science: molecular biology) identical dna sequences, several hundred nucleotides long, found at either end of transposons and the proviral dna, formed by reverse transcription of retroviral rna.

They are thought to have an essential role in integrating the transposon or provirus into the host dna. Long terminal repeats have inverted repeats, that is, sequences close to either end are identical when read in opposite directions. In proviruses the upstream long-terminal repeat acts as a promoter and enhancer and the downstream long-terminal repeat as a polyadenylation site.

5' LTR sequece

Hi, I want to check the 5' LTR sequence of my plasmid. I will like to confirm that it is a hybrid 5' LTR and not a wild type HIV-1 5' LTR. Can someone pls guide me on how I can evaluate this? Best, John

... Neuralgia When I started the stochastic activation of CD4 T cells, the latency was overcome by the Tat-mediated transactivation of the LTR, so the virus gene transcription and production of infection-competent viral particles reconstituted the viral reservoir. Thanks a bunch!!

... endogenous HERV-K progeny. We also show that this element amplifies via an extracellular pathway involving reinfection, at variance with the non-LTR-retrotransposons (LINEs SINEs) or LTR-retrotransposons, thus recapitulating ex vivo the molecular events responsible for its dissemination in the ...
