NCIt definition : Transcription initiation factor TFIID subunit 4 (1085 aa, 110 kDa) is encoded by
the human TAF4 gene. This protein is involved in the modulation of transcription.;
NCIt note : TBP-Associated Factor 4, containing 1 TAFH/NHR1 domain, is one of the larger subunits
of the multimeric TFIID complex that mediates promoter responses to various activators
and repressors. A component of the TFTC-HAT complex, TAF4 interacts with transcription
factor CREB and other proteins containing glutamine-rich regions and potentiates transcriptional
activation by the AF-2S of the RAR, THR and vitamin D3 receptor.;
