Fig. 2.
EMSA on the FT1 footprint of the ATR bound by Gata-1 factor present in MEL extract but not Jurkat extract.
Competitors and probes with mutations that remove the 5′, 3′, or both noncanonical Gata-1 sites (FT1B, FT1C, and FT1D, respectively) and a consensus Gata-1 competitor are indicated, as are antibodies used in supershift experiments. M indicates MEL extract; J, Jurkat extract.
