UniProt Comments
TAFs are components of the transcription factor IID (TFIID) complex that is essential for mediating regulation of RNA polymerase transcription. Core scaffold of the TFIID complex. Acts as a histone acetyltransferase involved in the light regulation of growth and gene expression. Required for H3K9, H3K27, and H4K12 acetylation on the target promoters.
