Transcription factor IIIA is a protein that in humans is encoded by the GTF3A gene.

It was first purified and identified as the first mammalian gene-specific activator by Robert G. Roeder in 1980, and later characterized by Wolffe and Brown in 1988.

The TFIIIA in Xenopus was the first zinc finger protein discovered.
