NettetOkamura et al. (2000) found that mouse Impact was imprinted and expressed from the paternal allele only. They identified a CpG island within intron 1 of the mouse gene that has a tandem repeat structure characteristic of imprinted genes, and this CpG island was highly methylated on the maternal allele. Nettetmouse models provided important insights into regulation of imprinted gene expression in the PWS/AS region. The coordinated regulation of the imprinted genes within the PWS/AS domain is mediated by a bipartite imprinting center (IC), composed of PWS-IC, a 4.3-kb sequence, which includes the SNRPN promoter/exon 1 and AS-IC, a 880-bp … precept by preceptNettetAbstract.

That imprinting might be a feature of mammalian development was suggested in breeding experiments in mice carrying reciprocal chromosomal translocations. Nucleus transplantation experiments in mouse zygotes in the early 1980s confirmed that normal development requires the contribution of both the maternal and paternal genomes.
