The Tet-On Advanced transactivator (also known as rtTA2 S-M2) is an alternative version of Tet-On that shows reduced basal expression, and functions at a 10-fold lower Dox concentration than Tet-Off. In addition, its expression is considered to be more stable in eukaryotic cells due to being human codon optimized and utilizing three minimal ...
The transactivator gene expresses a transcription factor that binds to specific promoter region of DNA. By binding to the promoter region of a gene, the transcription factor causes that gene to be expressed. The expression of one transactivator gene can activate multiple genes, as long as they have the same, specific promoter region attached.
Rev is a transactivating protein that is essential to the regulation of HIV-1 (and other lentiviral) protein expression.A nuclear localization signal is encoded in the rev gene, which allows the Rev protein to be localized to the nucleus, where it is involved in the export of unspliced and incompletely spliced mRNAs.

Reverse transcription loop-mediated isothermal amplification (RT-LAMP) is a one step nucleic acid amplification method to multiply specific sequences of RNA. It is used to diagnose infectious disease caused by RNA viruses. [1] It combines LAMP [2] DNA-detection with reverse transcription, making cDNA from RNA before running the reaction. [3]
Like other lentiviruses, HIV-1 encodes a trans-activating regulatory protein (Tat), which is essential for efficient transcription of the viral genome. [7] [8] Tat acts by binding to an RNA stem-loop structure, the trans-activation response element (TAR), found at the 5′ ends of nascent HIV-1 transcripts.
A reverse transcriptase (RT) is an enzyme used to convert RNA genome to DNA, a process termed reverse transcription.Reverse transcriptases are used by viruses such as HIV and hepatitis B to replicate their genomes, by retrotransposon mobile genetic elements to proliferate within the host genome, and by eukaryotic cells to extend the telomeres at the ends of their linear chromosomes.
