Genomic imprinting: CTCF protects the boundaries

Curr Biol. 2004 Apr 6;14(7):R284-6. doi: 10.1016/j.cub.2004.03.026.

Abstract

The DNA-binding protein CTCF, which acts as a chromatin 'insulator', regulates imprinting of the mammalian Igf2 and H19 genes in a methylation-sensitive manner. It has now been shown that CTCF is also required for protection against de novo methylation of the differentially methylated domain of H19 in the female germline.
