"WebEven though the TATA box is present in many eukaryotic promoters, it is not contained in the majority of promoters. One study found less than 30% of 1031 potential promoter regions contain a putative TATA box motif in humans. In Drosophila, less than 40% of 205 core promoters contain a TATA box.

WebSome biologists prefer to restrict the range of the eukaryotic promoter to the core promoter, or polymerase binding site, and refer to these additional sites as promoter-proximal elements, because they are usually found within a few hundred base pairs upstream of the transcriptional start site.
