Presence of a functional but dispensable Nuclear Export Signal in the HTLV-2 Tax protein [PDF]
, 2005 Background Human T-cell leukemia virus type 1 and type 2 are related human retroviruses. HTLV-1 is the etiological agent of the Adult T-cell Leukemia/Lymphoma and of the Tropical Spastic Paraparesis/HTLV-1 Associated Myelopathy, whereas, HTLV-2 infection

A trans-activator-like structure in RCNMV RNA1 evokes the origin of the trans-activator in RNA2
PLOS Pathogens, 2020 The Red clover necrotic mosaic virus (RCNMV) genome consists of two plus-strand RNA genome segments, RNA1 and RNA2. RNA2 contains a multifunctional RNA structure known as the trans-activator (TA) that (i) promotes subgenomic mRNA transcription from RNA1, (ii) facilitates replication of RNA2, and (iii) mediates particle assembly and copackaging of ...

Trans-activation of the human immunodeficiency virus long terminal repeat sequences, expressed in an adenovirus vector, by the adenovirus E1A 13S protein [PDF]
, 1988 The human immunodeficiency virus 1 (HIV-1) long terminal repeat (LTR) sequences were inserted into adenovirus in place of the E1 region. The HIV-1 LTR contained in this recombinant adenovirus responds to trans-activation by tatIII in a HeLa cell line ...

An emerging and variant viral promoter of HIV-1 subtype C exhibits low-level gene expression noise
Retrovirology, 2021 Background We observe the emergence of several promoter-variant viral strains in India during recent years. The variant viral promoters contain additional copies of transcription factor binding sites present in the viral modulatory region or enhancer ...

Bioassay for trans-activation using purified human immunodeficiency virus tat-encoded protein: trans-activation requires mRNA synthesis. [PDF]
Proceedings of the National Academy of Sciences, 1989 Expression of the human immunodeficiency virus tat-encoded protein (Tat) is required for virus replication. A genetic approach was used to facilitate the purification of biologically active Tat. A recombinant Tat protein containing a stretch of six histidine residues and a protease cleavage site was engineered and purified to greater than 95 ...

Activation of the U2 snRNA promoter by the octamer motif defines a new class of RNA polymerase II enhancer elements [PDF]
, 1988 The recent discovery that the activation domains of transcriptional activators (e.g., GAL4) from a number of species are interchangeable has led to the concept of a general mechanism for activation of RNA polymerase II genes.
