In addition to the effect on ribonucleotide reductase, hydroxyurea causes changes at the gene expression level. In the presence of hydroxyurea, the transcription factor GATA2 becomes upregulated, turning on the expression of the y-globin gene, while the transcription factor BCL11A which is involved in the silencing of the y-globin gene, is rendered inactive. Q6: BCL11A is a   and a transcriptional  of the y-globin gene.
