Target Background

Transcription factor TFIID is one of the general factors required for accurate and regulated initiation by RNA polymerase II. TFIID is a multimeric protein complex that plays a central role in mediating promoter responses to various activators and repressors. Required in complex with TBPL2 for the differentiation of myoblasts into myocytes. The complex replaces TFIID at specific promoters at an early stage in the differentiation process.
Gene References into Functions
  1. Data show that transcription cofactor TAF3 is required for transcription of the alpha spectrin SPTA1 gene. PMID: 23935956
  2. Study shows that H3K4me3-TAF3 interactions direct global TFIID recruitment to active genes, some of which are p53 targets. Further analyses show that H3K4me3 enhances p53-dependent transcription by stimulating preinitiation complex formation. PMID: 23452851
  3. Study shows that this TAF3 activity is critical for early lineage segregation during stem cell differentiation. PMID: 21884934
  4. Data identified TAF3 as an evolutionarily conserved negative regulator of p53 transcription activation function. PMID: 18549481
