A model for the interaction of TFIID with TATA box-containing vs. TATA-less, DPE-containing promoters. Depicted are two postulated TFIID–promoter interactions, not excluding other types of functionally important interactions between TFIID and core promoters. The lines between TFIID and the Inr indicate interactions between components of TFIID, such as TAFII150 and/or TAFII250, and the Inr.
