[https://www.uniprot.org/uniprot/FOXK2_HUMAN FOXK2_HUMAN] Recognizes the core sequence 5'-TAAACA-3'. Binds to NFAT-like motifs (purine-rich) in the IL2 promoter. Also binds to HIV-1 long terminal repeat. May be involved in both positive and negative regulation of important viral and cellular promoter elements.<ref>PMID:1909027</ref> <ref>PMID:1339390</ref>

== 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.
