- _5 value "A striking feature of this element is its palindrome sequences and eight-base pair direct repeats. We have purified to near homogeneity a 66-68-kDa protein that binds to this region and have designated it alpha-PAL {Nrf1}. The alpha-PAL-binding site extends from -74 to -10. By methylation protection analysis and mobility shift assay, the alpha-PAL-binding site is shown to be two adjacent sites, one with high and one with lower affinity, which bind alpha-PAL in a noncooperative manner. When the high affinity binding site is cloned upstream of the adenovirus 2 core promoter, in vitro transcription is stimulated 2-3-fold. When linked to a CAT reporter gene, activity of the eIF-2 alpha {eif2s1} promoter shows an approximate 2-fold dependence on the alpha-PAL element {in a leukemia cell line}." provenance.
