Dec 15, 2023 · Here, studying the oncogenic fusion TF PAX3-FOXO1 (P3F) from alveolar rhabdomyosarcoma (aRMS), we show that a single cysteine in the activation domain (AD) of P3F is important for a small alpha...

Nov 3, 2000 · Here we show that p300 works as a co-activator of the transcription factor Pax 8 on the thyroperoxidase gene promoter. Consistent with its role as co-activator, p300 potentiates Pax 8-activated transcription.

Nov 3, 2000 · Here we show that p300 works as a co-activator of the transcription factor Pax 8 on the thyroperoxidase gene promoter. Consistent with its role as co-activator, p300 potentiates Pax 8-activated transcription. Furthermore, we provide evidence supporting the formation of a complex between both factors in vivo and in vitro.

Apr 22, 2011 · Here, we show that co-expression of histone acetyltransferase E1A binding protein p300 dramatically enhances Pax5-mediated transcriptional activation. The p300-mediated enhancement is dependent on its intrinsic histone acetyltransferase activity.

Jul 1, 2005 · Our results describe the first dominant negative missense mutation in a paired domain and provide evidence for a crucial role of the p300 coactivator in mediating the functional synergism between PAX8 and TTF-1 in thyroid-specific gene expression.

PAX’s S300 is the latest integrated retail payment solution for retail merchants who wish to offer high levels of transactional security combined with contactless, e-signature, magnetic stripe and Chip & PIN.

The homeodomain transcription factors brain-4, pax-6, and cdx-2 have been shown to bind to these sites and to transactivate glucagon gene expression. In the present study, we investigated the interaction of cdx-2 and pax-6 with p300, a co-activator coupled to …

Here we show that p300 works as a co-activator of the transcription factor Pax 8 on the thyroperoxidase gene promoter. Consistent with its role as co-activator, p300 potentiates Pax...

Here we show that p300 works as a co-activator of the transcription factor Pax 8 on the thyroperoxidase gene promoter. Consistent with its role as co-activator, p300 potentiates Pax 8-activated transcription.

We show that the Gal4- p300 deletion mutant 964 -1922, containing the CH3 domain, does not interact with Pax 8. We envisage the amino-terminal portion of this mutant as masking the CH3 domain...
