A box named for them binds C-myc and other (*) basic helix-loop-helix proteins.
Bicoid patterning in Drosophila is driven by one of these structures immediately surrounded by Homie and Nhomie and named for the even-skipped stripe 2 protein.  Hi-C and ChIA-PET were developed to improve 3C methods for identifying these structures. They are considered flexible in the "billboard" model. A complex of HMG-1, NF-κB, and IRF-3 occurs at one of these structures named for interferon-beta. They are "trapped" using P-element transposons. In yeast, these structures are called UAS. A box named for them binds C-myc and other (*) basic helix-loop-helix proteins. These structures loop because of cohesin-associated proteins, which allows them to bind the Mediator complex either upstream or downstream. These cis-acting elements are often thousands of base-pairs away from where RNA polymerase binds. For 10 points, name these DNA sequences that activate transcription along with promoters.
