scription start site in many genes that lack a TATA-box promoter. Because of its position, this regulatory sequence is called the downstream promoter element (DPE). The DPE facilitates transcription of TATA-less genes that contain it by increasing TFIID binding.

In addition to general transcription factors, specific activators and repressors regulate transcription of genes by Pol II. In the next section we will examine how these regulatory proteins influence Pol II transcription initiation.
