生化/生理作用
The transcription factor IIA (TFIIA) has been shown to bind to the TBP-DNA complex and to increase the affinity of TBP for the TATA element. Human TFIIA consists of three subunits of 35 kDa ( α subunit), 19 kDa ( β subunit) and 12 kDa ( γ subunit). The α and β subunits are derived from the product, p55, of a single gene by an unknown mechanism. However, recombinant p55, in combination with a 12 kDa subunit ( γ subunit), retains native TFIIA activity.

A native gel electrophoresis DNA binding assay was used to resolve complexes formed on the adenovirus Major Late Promoter by general transcription factors and RNA polymerase II. Five sets of complexes containing distinct components were identified. These complexes were generated

TFIIA is a transcription factor that, by interacting with the TATA-binding subunit (TBP) of TFIID, modulates transcription initiation by RNA polymerase II in vitro. By use of a mobility shift assay, TFIIA was purified from HeLa cells as a complex

The general transcription factor TFIIA was purified from yeast. A key step in the purification was affinity chromatography using a column containing the adenovirus major late promoter with bound recombinant TFIID to which TFIIA binds with high affinity. TFIIA activity
