  • PubMed Abstract: 

    The nuclear factor of activated T cells (NFAT) and the AP-1 heterodimer, Fos-Jun, cooperatively bind a composite DNA site and synergistically activate the expression of many immune-response genes. A 2.7-A-resolution crystal structure of the DNA-binding domains of NFAT, Fos and Jun, in a quaternary complex with a DNA fragment containing the distal antigen-receptor response element from the interleukin-2 gene promoter, shows an extended interface between NFAT and AP-1, facilitated by the bending of Fos and DNA. The tight association of the three proteins on DNA creates a continuous groove for the recognition of 15 base pairs.
