Schematic diagrams of the 5’-flanking sequences of the <i>Oog1</i> coding regions.

<p>A. Locations of putative transcription factor binding sites in the 3.9 kb <i>Oog1</i> promoter region (on chromosome 12, NT_039551) are shown by arrows. E-box (-188 bp), SP1 binding element (-1369 bp), and NBEs (-2829 bp and -3490 bp) are conserved among upstream regions of the five copies of <i>Oog1</i>. B. Promoter regions of the five copies of <i>Oog1</i>. All five sequences share a ~3.9 kb long, highly homologous region including a TATA box. Some sequences have sequence insertions at -0.7 kb, -2.7 kb, and -3.2 kb from the TATA box. The sequences on chromosome 4 (the upstream regions of NM_001007077 and NM_001177542) have the largest gaps at -2.7 kb.
