Imprinted genes harbor discrete regions which are differentially methylated in gametes; usually the final differential methylation patterns in adults are established during embryogenesis through modifications of the initial methylation patterns in gametes. Previous reports have shown that a 200-bp region termed region II within the CpG island of the mouse imprinted U2afbp-rs gene is methylated in oocytes but not in sperm, suggesting that this region is a center for the propagation of methylated CpGs on the maternal allele and is also a candidate for an imprinting control element. To determine whether region II is required for the imprinted methylation of this gene at the endogenous locus, we generated mice carrying a deletion of this region. We herein show that parental methylation differences still exist in the CpG island on the region II-deleted allele. These findings suggest that region II is dispensable for the imprinted methylation of the U2afbp-rs gene.
