VEZF1 Elements Mediate Protection from DNA Methylation
Figure 7
VEZF1 interacts with the HS4 insulator in vivo.
(A) ChIP analysis of VEZF1 and CTCF interactions at the β-globin locus in (A) 6C2 erythroid progenitor cells or (B) 10 day embryonic erythrocytes. DNA enrichments at the βA promoter or the HS4 and 3′HS insulators were normalized to a negative control located in the 16 kb condensed chromatin region upstream of the β-globin locus.
