摘要

Comprehensive understanding of mechanisms of epigeneticregulation requires identification of molecules boundto genomic regions of interest in vivo. However, nonbiasedmethods to identify molecules bound to specificgenomic loci in vivo are limited. To perform biochemicaland molecular biological analysis of specific genomicregions, we developed the insertional chromatin immunoprecipitation(iChIP) technology to purify the genomicregions of interest [1]. The scheme of iChIP is as follows:(i) A repeat of the recognition sequence of an exogenousDNA-binding protein such as LexA is inserted intothe genomic region of interest in the cell to be analyzed.(ii) The DNA-binding domain (DNA DB) of the exogenousDNA-binding protein is fused with a tag(s) and anuclear localization signal(s) and expressed into the cellto be analyzed.
