Functional sequestration of transcription factor activity by repetitive DNA.

Abstract excerpt

Higher eukaryote genomes contain repetitive DNAs, often concentrated in transcriptionally inactive heterochromatin. Although repetitive DNAs are not typically considered as regulatory elements that directly affect transcription, they can contain binding sites for some transcription factors. Here, we demonstrate that binding of the transcription factor CCAAT/enhancer-binding protein alpha (C/EBPalpha) to the mouse...
