Figure 1. KROX-26 genomic DNA sequence. The NarI/Bst1107I genomic DNA fragment from BAC clone RP11-285G1 contains the entire KROX-26 open reading frame (underlined) as well as 2.4 kb of upstream sequence and 1.3 kb of downstream sequence. Several TATA and CCAAT box consensus sites in the upstream region are shown in bold, and the conserved polyadenylation site in the 3'-untranslated region is underlined. The sequence differences between KROX-26 and the HKR-T1 cDNA sequence are indicated in bold and italicized lower case in positions 2517, 2518, and 3074.
