Genome-wide mapping of in vivo SCL/DNA interactions in erythroid cells

ABSTRACT: We have previously proposed two distinct molecular mechanisms by which SCL binds its targets in hematopoiesis; either by direct contact with specific DNA sequences or by indirect recruitment through interaction with other proteins. We have established that direct DNA binding is the major non-redundant mechanism SCL exerts in red cells. A DNA-binding mutant form of SCL (SCLRER) had detrimental effect on erythropoiesis in vivo. To extend these data to a molecular and mechanistic level, we have set out to identify the genomic sequences bound by SCL in vivo in erythroid precursors; we performed anti-SCL ChIP assays on immature, Ter119- erythroid cell populations isolated from day E12.5 wild-type (SCLWT/WT) fetal livers followed by ultra-throughput sequencing (ChIP-SEQ). To compare SCL’s dir
