In order to determine which sequences in the GATA - 1 promoter are crucial for activation by the ME26 viral protein , we made deletions of the promoter , cloned them into a luciferase expression vector and tested their activity in mouse fibroblasts , which do not express GATA - 1 .
 GENE: GATA - 1 promoter; GENE: ME26 viral protein; GENE: luciferase; GENE: GATA - 1
