Nishikawa, Jun-ichi, Kokubo, Tetsuro, Horikoshi, Masami, Roeder, Robert G., Nakatani, Yoshihiro

The transcription initiation factor TFIID, consisting of the TATA box-binding protein (TBP) and many TBP-associated factors (TAFs), plays a central role in both basal and activated transcription. An...

The Yeast TAF145 Inhibitory Domain and TFIIA Competitively Bind to TATA-Binding Protein

Kokubo, Tetsuro, Swanson, Mark J., Nishikawa, Jun-ichi, Hinnebusch, Alan G., Nakatani, Yoshihiro

The Drosophila 230-kDa TFIID subunit (dTAF230) interacts with the DNA binding domain of TATA box-binding protein (TBP) which exists in the same complex. Here, we characterize the inhibitory domain in...

The transcriptional co-activator P/CAF potentiates TGF-β/Smad signaling

Itoh, Susumu, Ericsson, Johan, Nishikawa, Jun-ichi, Heldin, Carl-Henrik, Ten Dijke, Peter

Smads perform pivotal functions in the intracellular signaling of transforming growth factor-β (TGF-β). TGF-β-mediated activation of TGF-β type I receptor stimulates the phosphorylation of Smad2...
