- Abstract
We have isolated full-length cDNA clones for apolipoprotein AI from a human fetal liver cDNA library made in the vector lambda gt10. One such clone, pBL13AI, was 965 nucleotides long and contained the entire preproapolipoprotein AI sequence, in addition to 86 nucleotides of 5' untranslated region and 75 nucleotides of the 3' untranslated region. The complete structure of this clone is presented. Furthermore, we have obtained a 20-kb genomic fragment from a human genomic library, encompassing the entire apo AI gene. Sequence analysis of the gene shows that the coding region is interrupted by three introns of 197, 187, and 588 bp, respectively. Digestion of the DNA of various individuals with the endonuclease Msp I revealed a new restriction site polymorphism in the apo AI gene.
