Parental and sexual conflicts over the Peg3 imprinted domain
In the current study, the imprinting control region of the mouse Peg3 domain was deleted to test its functional impact on animal growth and survival. The paternal transmission of the deletion resulted in complete abolition of the transcription of two paternally expressed genes, Peg3 and Usp29, causing the reduced body weight of the pups. In contrast, the maternal transmission resulted in the un...
متن کاملRegulation and Function of the Peg3 Imprinted Domain
A subset of mammalian genes differ functionally between two alleles due to genomic imprinting, and seven such genes (Peg3, Usp29, APeg3, Zfp264, Zim1, Zim2, Zim3) are localized within the 500-kb genomic interval of the human and mouse genomes, constituting the Peg3 imprinted domain. This Peg3 domain shares several features with the other imprinted domains, including an evolutionarily conserved ...
متن کاملAllele-specific demethylation at an imprinted mammalian promoter
A screen for imprinted genes on mouse Chromosome 7 recently identified Inpp5f_v2, a paternally expressed retrogene lying within an intron of Inpp5f. Here, we identify a novel paternally expressed variant of the Inpp5f gene (Inpp5f_v3) that shows a number of unusual features. Inpp5f_v3 initiates from a CpG-rich repeat region adjoining two B1 elements, despite previous reports that SINEs are gene...
متن کاملCTCF is the master organizer of domain-wide allele-specific chromatin at the H19/Igf2 imprinted region.
A paternally methylated imprinting control region (ICR) directs allele-specific expression of the imprinted H19 and Igf2 genes. CTCF protein binding in the ICR is required in the maternal chromosome for insulating Igf2 from the shared enhancers, initiation of the H19 promoter transcription, maintaining DNA hypomethylation, and chromosome loop formation. Using novel quantitative allele-specific ...
متن کاملAllele-specific histone modifications regulate expression of the Dlk1-Gtl2 imprinted domain.
Dlk1 and Gtl2 are reciprocally expressed imprinted genes located on mouse chromosome 12. The Dlk1-Gtl2 locus carries three differentially methylated regions (DMRs), which are methylated only on the paternal allele. Of these, the intergenic (IG) DMR, located 12 kb upstream of Gtl2, is required for proper imprinting of linked genes on the maternal chromosome, while the Gtl2 DMR, located across th...
