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, None) , ( protein: EKLF, None) , ( DNA: high-affinity binding site, None) , ( DNA: proximal promoter, None) , ( DNA: beta-globin gene, None) , ( protein: erythroid Kruppel-like factor, None)
