FIG. 4.

Sequences from the fetal 1b proximal p45-NF-E2 promoter and EKLF erythroid hypersensitive site 1 bind CP2. Binding of recombinant CP2 and GATA-1 to the p45 NF-E2 promoter (A) and the EKLF promoter (B) was assessed by EMSA. The positions of the GATA-1 and CP2 complexes are indicated. (C) The effects of the addition of recombinant CP2 and anti-CP2 antibody on GATA-1 and CP2 complex formation on the p45 NF-E2 and EKLF promoters were assessed by EMSA. The positions of the GATA-1 and CP2 complexes are indicated.
