SOLUTION NMR STRUCTURE OF THE CORE NFATC1/DNA COMPLEX, 18 STRUCTURES

Overview

The nuclear factor of the activated T cell (NFAT) family of transcription, factors regulates cytokine gene expression by binding to the, promoter/enhancer regions of antigen-responsive genes, usually in, cooperation with heterologous DNA-binding partners. Here we report the, solution structure of the binary complex formed between the core, DNA-binding domain of human NFATC1 and the ARRE2 DNA site from the, interleukin-2 promoter. The structure reveals that DNA binding induces the, folding of key structural elements that are required for both, sequence-specific recognition and the establishment of cooperative, protein-protein contacts. The orientation of the NFAT DNA-binding domain, observed in the binary NFATC1-DBD*/ DNA complex is distinct from that seen, in the ternary NFATC2/AP-1/DNA complex, suggesting that the domain, reorients upon formation of a cooperative transcriptional complex.
