In the toad Xenopus laevis alpha-MSH controls skin darkening during background adaptation, and the level of POMC gene transcription in the intermediate lobe depends on the color of the background. In the lobe, two structurally different POMC proteins are produced from two mRNAs that are transcribed to approximately the same level from two POMC genes (A and B). We previously reported the entire nucleotide sequence of Xenopus POMC gene B. To identify conserved-- and thus potential regulatory--DNA elements in the Xenopus POMC gene, we here report the determination and analysis of the complete nucleotide sequence of Xenopus POMC gene A and its 5'- and 3'-flanking regions. Comparison of the two Xenopus POMC genes revealed, in addition to the exons, three highly conserved regions. First, the promoter regions are greater than 90% identical. The second region concerns JH12 repetitive elements situated at approximately the same position in both genes. These elements are greater than 86% identical. The third region is a 500-bp sequence just upstream of exon three (63% identity). Besides these three large regions, several small regions with significant identity were found at similar positions in the two POMC genes. The fact that, except for the JH12 element, the repetitive elements are not conserved between the two POMC genes indicates that these repeats are not functionally important."xsd:string |
