First, we show that mutations in the LEF-1 -binding site inhibit the activity of multimerized copies of the HIV-1 enhancer in Jurkat T cells , and that LEF-1 /GAL4 can activate a GAL4-substituted HIV-1 enhancer 80- to 100-fold in vivo.
 DNA: LEF-1 -binding site; DNA: HIV-1 enhancer; protein: LEF-1; DNA: GAL4-substituted HIV-1 enhancer; cell line: Jurkat T cells; DNA: multimerized copies; DNA: HIV-1 enhancer; protein: LEF-1 /GAL4; protein: LEF-1
