CC   -!- FUNCTION: Functions as a component of the DNA-binding general
CC       transcription factor complex TFIID. May also function as a component of
CC       transcription regulatory histone acetyl transferase (HAT) complexes
CC       such as SAGA. Binding of TFIID to a promoter (with or without TATA
CC       element) is the initial step in preinitiation complex (PIC) formation.
CC       TFIID plays a key role in the regulation of gene expression by RNA
CC       polymerase II through different activities such as transcription
CC       activator interaction, core promoter recognition and selectivity, TFIIA
CC       and TFIIB interaction, chromatin modification, facilitation of DNA
CC       opening and initiation of transcription (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Component of the DNA-binding general transcription factor
CC       complex TFIID. Component of histone acetyl transferase (HAT) complexes
CC       such as SAGA (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250}.
CC   -!- DEVELOPMENTAL STAGE: Expressed in late sporogonial stages.
CC       {ECO:0000269|PubMed:16691553}.
CC   -!- SIMILARITY: Belongs to the TAF9 family. {ECO:0000305}.
