A differentially methylated region within the gene Kcnq1 functions as an imprinted promoter and silencer

Abstract excerpt

The imprinted gene cluster on mouse distal chromosome 7 contains a differentially methylated CpG island that maps within the Kcnq1 gene that has been shown to be required for the imprinting of multiple genes. To evaluate models for how this imprinting control region (ICR) regulates imprinting, we have characterized it structurally and functionally. We show that the region contains a promoter for a paternally...
