A small 95-bp fragment of the TCR alpha control region that contains the TCF-1 alpha binding site juxtaposed between a cAMP-response element ( the CRE or T alpha 1 motif ) and the binding site for a distinct lymphoid-specific protein ( TCF-2 alpha ) behaved as a potent T-cell-specific enhancer in vivo .
