ChIP-Seq analysis of Ldb1/Tal1/Gata1 complexes (Ldb1 complexes). (A) Frequency of colocalized Ldb1, Tal1, and Gata1 binding sites. Shown are (left) all sites , (center) gene binding sites, and (right) erythroid fingerprint gene binding sites. Gene binding sites are defined as those sites within 5 kb of a TSS or within a gene body. Erythroid fingerprint genes are as described.²⁴  (B) ChIP-over-input fold enrichment at Ldb1, Tal1, and Gata1 binding sites. G, Gata1; L, Ldb1; T, Tal1.
