Protein kinase NII and the regulation of rDNA transcription in mammalian cells.

abstract：:Transcription factor binding sites (TFBSs) are short DNA sequences interacting with transcription factors (TFs), which regulate gene expression. Due to the relatively short length of such binding sites, it is largely unclear how the specificity of protein-DNA interaction is achieved. Here, we have performed a genome-w...
