Publication Abstract from PubMed
Interleukin enhancer binding factor (ILF) binds to the interleukin-2 (IL-2) promoter and regulates IL-2 gene expression. In this study, the 3D structure of the DNA-binding domain of ILF was determined by multidimensional NMR spectroscopy. NMR structure analysis revealed that the DNA-binding domain of ILF is a new member of the winged helix/forkhead family, and that its wing 2 contains an extra alpha-helix. This is the first study to report the presence of a C-terminal alpha-helix in place of a typical wing 2 in a member of this family. This structural difference may be responsible for the different DNA-binding specificity of ILF compared to other winged helix/forkhead proteins. Our deletion studies of the fragments of ILF also suggest that the C-terminal region plays a regulatory role in DNA binding.
