A schematic diagram of the C/EBPα gene locus.

The gene does not contain introns; therefore, the coding region is contained within one exon represented as an open box. The domains discussed in the text are indicated by the shaded boxes. The position of the primers used for PCR-SSCP analysis for each region (1 through 4) are indicated by the arrows above (forward or sense primers) and below (reverse or antisense primers) the schematic. Abbreviations: ADM, activation domain modules; BR, basic region; and L-ZIP, leucine zipper.
