Transcriptional adapter 2-alpha is a protein that in humans is encoded by the TADA2A gene.Many DNA-binding transcriptional activator proteins enhance the initiation rate of RNA polymerase II-mediated gene transcription by interacting functionally with the general transcription machinery bound at the basal promoter. Adaptor proteins are usually required for this activation possibly to acetylate and destabilize nucleosomes thereby relieving chromatin constraints at the promoter.
