TAFs are components of the transcription factor IID (TFIID) complex that is essential for mediating regulation of RNA polymerase transcription. Required for proper pollen function. May stabilize the interaction of TFIID with selected promoters. Not redundant with TAF6B. Component of the TFIID complex. TFIID is composed of TATA binding protein (TBP) and a number of TBP-associated factors (TAFs) whose MWs range from 14-217 kDa. Expressed in roots, leaves, inflorescences and siliques. Expressed in germinating pollen. Lethal when homozygote. Reduced pollen tube growth when heterozygote. Belongs to the TAF6 family.
