Abstract

Adrenomedullin (ADM), a peptide characterized by persistent hypotensive activity, is thought to be involved when the control mechanism of blood pressure is deranged, because its plasma concentration is upregulated in hypertensive patients. The receptor for ADM, a molecular complex consisting of calcitonin-receptor-like receptor (CRLR) and receptor-activity-modifying protein 2 (RAMP2), is activated through a unique intracellular transport mechanism. By analyzing the nucleotide sequences of bacterial artificial chromosome (BAC) clones, we have established that the gene encoding CRLR is spread over a genomic distance of 103,145 bases; it contains 15 exons interrupted by 14 introns, including 1 that spans more than 60 kilobases. Exons 1-3 constitute the 5' noncoding region; exons 4 through 15 are coding elements, of which exons 8 to 14 encode seven transmembrane domains. Eight novel single-nucleotide polymorphisms (SNPs) and their allelic frequencies in the Japanese population were found by direct sequencing of 32 alleles; two SNPs were in the 5' flanking region, one in exon 2, and the other five around intron-exon junctions. Eight haplotypes were constructed using these alleles in our Japanese population sample. The data establish...Continue Reading
