CC -!- FUNCTION: The TFIID basal transcription factor complex plays a major
CC role in the initiation of RNA polymerase II (Pol II)-dependent
CC transcription (By similarity). TFIID recognizes and binds promoters
CC with or without a TATA box via its subunit TBP, a TATA-box-binding
CC protein, and promotes assembly of the pre-initiation complex (PIC) (By
CC similarity). The TFIID complex consists of TBP and TBP-associated
CC factors (TAFs), including TAF1, TAF2, TAF3, TAF4, TAF5, TAF6, TAF7,
CC TAF8, TAF9, TAF10, TAF11, TAF12 and TAF13 (By similarity). The TFIID
CC complex structure can be divided into 3 modules TFIID-A, TFIID-B, and
CC TFIID-C (By similarity). TAF8 is involved in forming the TFIID-B
CC module, together with TAF5 (By similarity). Mediates both basal and
CC activator-dependent transcription (By similarity). Plays a role in the
CC differentiation of preadipocyte fibroblasts to adipocytes, however,
CC does not seem to play a role in differentiation of myoblasts
CC (PubMed:14580349). Required for the integration of TAF10 in the TAF
CC complex (By similarity). May be important for survival of cells of the
CC inner cell mass which constitute the pluripotent cell population of the
CC early embryo (PubMed:11076765). {ECO:0000250|UniProtKB:Q7Z7C8,
CC ECO:0000269|PubMed:11076765, ECO:0000269|PubMed:14580349}.
CC -!- SUBUNIT: Component of the TFIID basal transcription factor complex,
CC composed of TATA-box-binding protein TBP, and a number of TBP-
CC associated factors (TAFs), including TAF1, TAF2, TAF3, TAF4, TAF5,
CC TAF6, TAF7, TAF8, TAF9, TAF10, TAF11, TAF12 and TAF13. Interacts with
CC TBP, TAF1, TAF6, TAF10, TAF11 and TAF13. Component also of a small TAF
CC complex (SMAT) containing TAF8, TAF10 and SUPT7L. Forms a heterodimer
CC with TAF10. Interaction with TAF10 is mediated mainly via its histone
CC fold domain while interaction with SUPT7L is via its C-terminal region.
CC {ECO:0000250|UniProtKB:Q7Z7C8}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000269|PubMed:11076765}. Cytoplasm
CC {ECO:0000269|PubMed:11076765}. Note=Localized in the cytoplasm and
CC transported from the cytoplasm to the nucleus in some cells, possibly
CC depending on the functional or developmental state of the cell.

CC -!- TISSUE SPECIFICITY: Low level of expression throughout the brain with
CC slightly higher expression in the hippocampus.
CC -!- DEVELOPMENTAL STAGE: Expressed ubiquitously at very low levels
CC throughout embryonic development. Higher levels of expression seen in
CC inner cell mass and heart. {ECO:0000269|PubMed:11076765}.
CC -!- DISRUPTION PHENOTYPE: Death during early embryonic development. The
CC inner cell mass cells of mutant embryos died of apoptosis.
CC {ECO:0000269|PubMed:11076765}.
CC -!- MISCELLANEOUS: 'Taube nuss' means 'empty nut' in German.
CC -!- SIMILARITY: Belongs to the TAF8 family. {ECO:0000305}.
