Studies on the organization of the human apolipoprotein B 100 gene.
The organization of five exons of the 3' terminal end of the human apolipoprotein B 100 (apo B 100) gene 1906, 184, 115, 7572 and 374 bp long have been determined from two overlapping EMBL3 human genomic clones extending over 18 kb. They encode more than 70% of the apo B 100 amino-acid sequence. The introns between these five exons were sequenced revealing the common intron/exon splice junction sequences. The 7572 bp exon is the longest exon so far reported for mammalian genes with the proposed sequence coding for the LDL receptor binding site. Its possible relationship to apolipoprotein B 48 is discussed.
