PRC2 is required to maintain expression of the maternal Gtl2-Rian-Mirg locus
PRC2 transcriptionally regulates the Gtl2-Rian-Mirg locus through DNAme at IG-DMR
IG-DMR serves as an enhancer of the maternal Gtl2-Rian-Mirg locus
PRC2 prevents de novo DNAme at IG-DMR for maternal Gtl2-Rian-Mirg locus expression
