Previous studies demonstrated correct tissueand temporal-specific expression of human 7and ~-globin genes in transgenic mice; however, expression was extremely low. When the erythroid-specific DNase I superhypersensitive (HS) sites that are normally located upstream of the human 13-globin locus were fused individually to 7" or 13-globin genes, expression increased to endogenous mouse globin levels but temporal specificity was lost. In contrast, when the HS sequences were combined with fragments containing both 7" and 13-globin genes, correct developmental regulation was restored. We suggest that human 7" to 13-globin gene switching during development results from competition of individual globin gene family members for interaction with the HS sequences and that factors influencing these competitive interactions determine temporal specificity.
