function:TFIIA is a component of the transcription machinery of RNA polymerase II and plays an important role in transcriptional activation. TFIIA in a complex with TBP mediates transcriptional activity.,similarity:Belongs to the TFIIA subunit 2 family.,subunit:TFIIA is a heterodimer of the large unprocessed subunit 1 and a small subunit gamma. It was originally believed to be a heterotrimer of an alpha (p35), a beta (p19) and a gamma subunit (p12). Interacts with NCOA6 general coactivator (By similarity). TFIIA forms a complex with TBP. Interacts with SV40 Large T antigen.,
