Previously we and others showed by targeted gene disruption that the zinc finger gene , erythroid Kruppel-like factor ( EKLF ), is required for expression of the beta-globin gene in mice , presumably through interaction with a high-affinity binding site in the proximal promoter .
 DNA: zinc finger gene; protein: EKLF; DNA: high-affinity binding site; DNA: proximal promoter; DNA: beta-globin gene; protein: erythroid Kruppel-like factor
