TAF(II)s are conserved components of the TFIID, TFTC and SAGA-related mRNA transcription complexes. In yeast (y), yTAF(II)17 is required broadly for transcription, but various other TAF(II)s appear to have more specialized functions. It is important to determine how TAF(II)s contribute to transcription in metazoans, which have larger and more diverse genomes. We have examined TAF(II) functions ...

Tenofovir alafenamide (TAF) is a phosphonoamidate prodrug of the nucleotide HIV reverse transcriptase inhibitor tenofovir (TFV). TAF is approved for the treatment of HIV-1 infection as part of the single-tablet regimen containing elvitegravir, cobicistat, emtricitabine, and TAF. When dosed once-daily, TAF results in approximately 90% lower levels of plasma TFV and a 4-fold increase in intracell...

Using an antiserum raised against tumour angiogenesis factor (TAF) we have developed a radioimmunoassay for retina and tumour angiogenesis factor(s). This antiserum was previously shown to bind to both human and animal tumour extracts and to inhibit the angiogenesis induced by TAF in vivo. TAF from rat Walker tumour was used for iodination by the chloramine-T method. An excess of 125I-labelled ...

TAF(II)105 is a TFIID-associated factor highly expressed in B lymphocytes. This subunit is found in a small portion of TFIID complexes and is homologous to human TAF(II)130 and Drosophila TAF(II)110. In the present study we show that TAF(II)105 is involved in transcription activation directed by the B cell-specific octamer element found in many B cell-specific genes. B cells overexpressing TAF(...

We have previously demonstrated that the human oestrogen receptor (hER) contains two transcriptional activation functions located in the N-terminal region (TAF-1) and in the hormone binding domain (TAF-2), which can act both independently and synergistically in a promoter- and cell-specific manner in animal cells. We have also demonstrated that hER can activate transcription from chimaeric oest...

BACKGROUND Thought-Shape Fusion (TSF) and Thought-Action Fusion (TAF) are cognitive distortions that are associated with eating and obsessional pathology respectively. Both involve the underlying belief that mere thoughts and mental images can lead to negative outcomes. TSF involves the belief that food-related thoughts lead to weight gain, body dissatisfaction, and perceptions of moral wrong-d...

BACKGROUND Tenofovir alafenamide (TAF) is a novel investigational prodrug of tenofovir (TFV) that permits enhanced delivery of TFV into peripheral blood mononuclear cells (PBMCs) and lymphatic tissues. A critical step in the intracellular metabolic activation of TAF is mediated by the lysosomal protease cathepsin A (CatA). Here, we investigated CatA levels together with intracellular metabolism...

The TATA box-binding protein (TBP) and TBP-associated factors (TAF(II)s) compose the general transcription factor TFIID. The TAF(II) subunits mediate activated transcription by RNA polymerase II by interacting directly with site-specific transcriptional regulators. TAF(II)s also participate in promoter recognition by contacting core promoter elements in the context of TFIID. To further dissect ...

OBJECTIVE To examine the relationship between thought-action fusion (TAF) and schizotypy. METHOD In two separate samples of undergraduate students (Ns = 77 and 64), correlations were computed between a measure of TAF and indices of schizotypy and fantasy proneness. RESULTS Positive correlations were found between TAF and various aspects of schizotypy (i.e. perceptual aberration, magical ide...

The human RNA polymerase II transcription factor B-TFIID consists of TATA-binding protein (TBP) and the TBP-associated factor (TAF) TAF(II)170 and can rapidly redistribute over promoter DNA. Here we report the identification of human TBP-binding regions in human TAF(II)170. We have defined the TBP interaction domain of TAF(II)170 within three amino-terminal regions: residues 2 to 137, 290 to 38...
