Schematic representation of the structure of the chicken and human E2A genes. Black lines represent assigned exons, grey lines represent exons lying in gap sequences; their exact position has not been determined. Open boxes represent the alternatively spliced E12 and E47 exons encoding the helix-loop-helix domain of these proteins. See Table 2 for the exact position of each of the exons.
