In this study, we investigated the effect of ER alpha (referred to throughout as ER ) on DNA-binding activities of transcription factors involved in regulating the expression of erythroid-specific genes , and, in particular, the histone H5 gene .
 ( DNA: erythroid-specific genes, None) , ( protein: transcription factors, None) , ( DNA: histone H5 gene, None) , ( protein: ER, None) , ( protein: ER alpha, None)
