[Antigen receptor response element] A short nucleotide sequence, designated ARRE-2, is found in the promoter region of the IL2 gene. It contains the binding site for a transcription factor (see also: gene expression), known as NFAT-1, which is expressed exclusively in T-cells after cell activation and appears to modulate the expression of the IL2 gene.
