The core promoter DNA elements bind and control preinitiation complex assembly containing Pol II, transcription factor and coactivators. They position the transcription start site and control transcriptional directionality and they respond to activators and repressors in their vicinity in a cell. The preinitiation complex contains two classes of factors. ...
