Imprinting chromatin

WitrynaChromatin regulators of genomic imprinting Genomic imprinting is an epigenetic phenomenon in which genes are expressed monoallelically in a parent-of-origin … Witryna1 lis 1999 · Most imprinted loci have key regulatory elements that are methylated on only one of the parental chromosomes. For several of these ‘differentially methylated regions’, recent studies establish that the unmethylated chromosome has a specialized chromatin organization that is characterized by nuclease hypersensitivity.
