Promoter transcription factors in ogn1 and ogn2 genes. Approximately 1.2 kilobases of the proximal promoter sequences of the Dicentrarchus labrax (Dl) ogn1 (located in linkage group 1A) and ogn2 (located in linkage group 22–25) are represented in the figure (solid line). Each vertical rectangle represents a transcription factor binding site predicted with the Matinspector software and below each rectangle the distance of the binding site relative to the beginning of the open reading frame (+ 1 base pairs-bp) is also shown. Red rectangles delimit the regions of the promoters that were enriched in chondrocyte, osteoblast, myocyte and adipocyte specific binding sites. To facilitate identification the different transcription factor binding sites for each cell type are represented in different colours as indicated in the colour chart
