Abstract

We report the structure of the human annexin VI gene and compare the intron-exon organization with the known structures of the human annexin I and II genes. The gene is approximately 60 kbp long and contains 26 exons. Consistent with the published annexin VI cDNA sequence, the genomic sequence at the 3' end does not contain a canonical polyadenylation signal. The genomic sequence upstream of the transcription start site contains TATAA and CAAT motifs. The spatial organization of the exons does not reveal any obvious similarities between the two halves of the annexin VI gene. Comparison of the intron-exon boundary positions of the annexin VI gene with those of annexins I and II reveals that within the repeated domains the break points are perfectly conserved except for exon 8, which is one codon smaller in annexin II. The corresponding point in the second half of annexin VI is represented by two exons, exons 20 and 21. The latter exon is alternatively spliced, giving rise to two annexin VI isoforms that differ with respect to a 6-amino acid insertion at the start of repeat 7.
