BATF, also known as SFA2, is a nuclear basic leucine zipper protein that belongs to the AP-1/ATF superfamily of transcription factors. BATF is strongly expressed in mature T and B lymphocytes, and is up-regulated after transformation by human T-cell leukemia virus type I. BATF functions as a tissue-specific modulator of the AP-1 transcription complex in human cells. BATF also associates with IFP35, a leucine zipper protein that translocates to the nucleus following IFN treatment.
