Using a combination of transfection , protein-DNA binding, and in vitro transcription methods , we have discovered the novel T-cell-specific transcriptional activator TCF-1 (for T-Cell Factor-1 ), which recognizes a T-cell-specific response element ( TCE ) located within the IL-2 promoter .
 protein: TCF-1; protein: T-Cell Factor-1; protein: novel T-cell-specific transcriptional activator; DNA: IL-2 promoter; DNA: T-cell-specific response element; protein: IL-2; DNA: TCE
