The imprinted mouse H19 gene exhibits maternal allele-specific expression and paternal allele-specific hypermethylation. We previously demonstrated that a 14-kb H19 minitransgene possessing 5' differentially methylated sequence recapitulates the endogenous H19 imprinting pattern when present as high-copy arrays. To investigate the minimal sequences that are sufficient for H19 transgene imprinting, we have tested new transgenes in mice. While transgenes harboring limited or no 3' H19 sequence indicate that multiple elements within the 8-kb 3' fragment are required for appropriate imprinting, transgenes incorporating 1.7 kb of additional 5' sequence mimic the endogenous H19 pattern, including proper imprinting of low-copy arrays. One of these imprinted lines had a single 15.7-kb transgene integrant. This is the smallest H19 transgene identified thus far to display imprinting properties characteristic of the endogenous gene, suggesting that all cis-acting elements required for H19 imprinting in endodermal tissues reside within the 15.7-kb transgenic sequence.
