RNA and protein synthesis mechanisms

The gene defective in Menkes disease, an X-linked recessive disturbance of copper metabolism, has been isolated and predicted to encode a copper-binding P-type ATPase. We determined the complete exon—intron structure of the Menkes disease gene, which spans about 150 kb of genomic DNA. The gene contains 23 exons, and the ATG start codon is in the second exon. All of the exon—intron boundaries were sequenced and conformed to the GT/AT rule, except for the 5′ splice site of intron 9. A preliminary comparison demonstrated a striking similarity between the exon structures of the Menkes and Wilson disease genes, giving insight into their evolution.
