Analysis of changes to mRNA levels and CTCF occupancy upon TFII-I knockdown.

ABSTRACT: CTCF is a key regulator of nuclear chromatin structure, chromatin organization and gene regulation. The impact of CTCF on transcriptional output is quite varied, ranging from repression, to transcriptional pausing and transactivation. The multifunctional nature of CTCF is mediated, in part, through differential association with protein partners having unique properties. We identified the general transcription factor TFII-I as an interacting partner of CTCF. To gain an understanding of the function of TFII-I in regulating gene expression and CTCF binding genome wide, we conducted microarray experiments following TFII-I knockdown and chromatin immunoprecipitation of CTCF followed by next generation sequencing (ChIP-seq) from the same TFII-I depleted cells. Here, we described the experimental
