Enrichment of Ldb1 complex binding sites at erythroid genes and erythroid cis-regulatory elements. (A) Ldb1 complex binding sites at erythroid “fingerprint” genes.²⁴  (B-E) UCSC Genome Browser shots of Ldb1 complex binding at known or presumed cis-regulatory elements: (B) β-globin LCR, (C) α-globin (MARE) cis-regulatory region, (D) Runx1 locus, and (E) presumed cis-regulatory element near Zdhhc19. Binding sites for p300 and H3K27ac, H3K4me1 profiles in MEL cells, and mammalian conservation tracks are shown at the bottom.
