Abstract
Expression of globin genes in developing erythroid cells is controlled by upstream locus control regions. Activity of these regions in vivo requires an erythroid-specific nuclear factor (NF-E2) that binds AP-1-like recognition sites. Its tissue-specific component (p45 NF-E2) has been characterized by complementary DNA cloning as a new basic region-leucine zipper protein which dimerizes with a ubiquitous partner to form native NF-E2.
