Evidence is emerging that transcription factors (TFs) lacking methyl-CpG binding domains can interact with methylated DNA. This Analysis article reviews thein vitro and in vivoevidence for methylation-mediated interactions between TFs and DNA, and their functional consequences.
This Analysis provides a statistical evaluation of the core structure inherent to all gene-set analyses. The authors examine current implementations in available tools and show which factors affect valid and successful detection of gene sets.
