DESCRIPTION: RecName: Full=Transcription initiation factor TFIID subunit 8; AltName: Full=Protein taube nuss; AltName: Full=TBP-associated factor 8;
FUNCTION: Transcription factor TFIID is one of the general factors required for accurate and regulated initiation by RNA polymerase II. Mediates both basal and activator-dependent transcription. Plays a role in the differentiation of preadipocyte fibroblasts to adipocytes, however does not seem to play a role in differentiation of myoblasts. Required for the integration of TAF10 in the TAF complex (By similarity). May be important for survival of cells of the inner cell mass which constitute the pluripotent cell population of the early embryo.
SUBUNIT: TFIID is composed of TATA binding protein (TBP) and a number of TBP-associated factors (TAFs). Interacts with TBP, TAF1, TAF6, TAF10, TAF11 and TAF13. Component also of a small TAF complex (SMAT) containing TAF8, TAF10 and SUPT7L. Forms a heterodimer with TAF10. Interaction with TAF10 is mediated mainly via its histone fold domain while interaction with SUPT7L is via its C-terminal region (By similarity).
SUBCELLULAR LOCATION: Nucleus. Cytoplasm. Note=Localized in the cytoplasm and transported from the cytoplasm to the nucleus in some cells, possibly depending on the functional or developmental state of the cell.
TISSUE SPECIFICITY: Low level of expression throughout the brain with slightly higher expression in the hippocampus.
DEVELOPMENTAL STAGE: Expressed ubiquitously at very low levels throughout embryonic development. Higher levels of expression seen in inner cell mass and heart.
DISRUPTION PHENOTYPE: Death during early embryonic development. The inner cell mass cells of mutant embryos died of apoptosis.
MISCELLANEOUS: 'Taube nuss' means "empty nut' in German.
SIMILARITY: Belongs to the TAF8 family.
SIMILARITY: Contains 1 histone-fold domain.

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.

ModBase Predicted Comparative 3D Structure on Q9EQH4
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.
