The Estrogen receptor alpha cistrome defined by DamIP

ABSTRACT: We have developed a new method to study DNA-protein interaction in vivo called DamIP, which is based on fusing a protein of interest to a mutant form of DNA adenine methylatransferase (Dam) from E. coli. We showed previously that DamIP can efficiently identify in vivo binding sites of Dam-tethered human estrogen receptor alpha (hERα). In current study, we present the cistrome of hERα determined by DamIP and high throughput sequencing (DamIP-seq). The DamIP-seq defined hERα cistrome overlaps significantly with those determined by ChIP-chip or ChIP-seq, but identifies many new binding regions. As shown by conventional ChIP assay, many DamIP-seq unique hERα binding regions show relatively stable hERα binding, whereas DamIP-seq misses some regions with very transient hERα binding.
