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 Philippine postal system has a history spanning over 250 years. In 1767, the first post office in the Philippines was established in the city of Manila, which was later organized under a new postal district of Spain. [4] At first, the postal office served mainly to courier government and church documents.
Ten-eleven translocation methylcytosine dioxygenase 1 (TET1) is a member of the TET family of enzymes, in humans it is encoded by the TET1 gene.Its function, regulation, and utilizable pathways remain a matter of current research while it seems to be involved in DNA demethylation and therefore gene regulation, [5] [6] but is expressed as different isoforms which may have distinct functions.
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.
Telomerase reverse transcriptase (abbreviated to TERT, or hTERT in humans) is a catalytic subunit of the enzyme telomerase, which, together with the telomerase RNA component (TERC), comprises the most important unit of the telomerase complex. [5] [6] Telomerases are part of a distinct subgroup of RNA-dependent polymerases.
