ID:TAF9B_HUMAN DESCRIPTION: RecName: Full=Transcription initiation factor TFIID subunit 9B; AltName: Full=Neuronal cell death-related protein 7; Short=DN-7; AltName: Full=Transcription initiation factor TFIID subunit 9-like; AltName: Full=Transcription-associated factor TAFII31L; FUNCTION: Essential for cell viability. TAF9 and TAF9B are involved in transcriptional activation as well as repression of distinct but overlapping sets of genes. May have a role in gene regulation associated with apoptosis. TAFs are components of the transcription factor IID (TFIID) complex, the TBP-free TAFII complex (TFTC), the PCAF histone acetylase complex and the STAGA transcription coactivator-HAT complex. TFIID or TFTC are essential for the regulation of RNA polymerase II-mediated transcription. SUBUNIT: Binds TAF5 and TAF6. Component of TFIID and the TATA- binding protein-free TAF complex (TFTC). TFIID is composed of TATA binding protein (TBP) and a number of TBP-associated factors (TAFs). Binds N-terminal domain of p53/TP53 which is essential for transcription. SUBCELLULAR LOCATION: Nucleus (By similarity). SIMILARITY: Belongs to the TAF9 family.
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
