As conserved components of the transcription factor (TF) IID- and TFTC/SAGA-related complexes, TATA-binding protein-associated factors (TAF(II)s) are important for eukaryotic mRNA transcription. In yeast, genetic analyses suggest that, although some individual TAF(II)s are required for transcription of most genes, others have highly specialized functions. Much less is known about the functions ...

Tumour-derived adhesion factor (TAF) has been shown to be associated with breast, prostate and colorectal cancer (CRC), acting as tumour suppressor or tumour promoter by mechanisms not as yet understood. Here, we comparatively analyzed the expression profile of TAF in plasma, tumour and paired normal tissue from patients with CRC. In addition, we investigated the relationship between TAF and sy...

In Drosophila, a coordinate interplay between the Rel transcription factor Dorsal and the basic Helix-Loop-Helix transcription factor Twist initiates mesoderm formation by activating the zygotic expression of mesoderm-determining genes. Here, we show that TBP-associated-factors (TAF(II)s) within the basal transcription factor TFIID mediate transcriptional activation by Dorsal and Twist. Dorsal ...

The general transcription factor TFIID sets the mRNA start site and consists of TATA-binding protein and associated factors (TAF(II)s), some of which are also present in SPT-ADA-GCN5 (SAGA)-related complexes. In yeast, results of multiple studies indicate that TFIID-specific TAF(II)s are not required for the transcription of most genes, implying that intact TFIID may have a surprisingly special...

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 ...
