FIG. 3.

DNA sequence of the 5′ region of the mouse Fli-1 gene (1). Coordinates are shown relative to ATG initiation codon of the 51-kDa Fli-1 protein. The primers used to characterize the 5′ ends of Fli-1 transcripts are shown in boldface. The 5′ ends of major 5′ RACE products are indicated by unfilled and filled stars for the 745-A and CB7 cell lines, respectively. Major and minor transcription initiation sites further characterized by S1 and RNase mapping are indicated by large and thin arrowheads, respectively.
