ADAM is a recently discovered gene family that encodes proteins with a disintegrin and metalloproteinase. ADAMTS-1 is a gene encoding a new member protein of the ADAM family with the thrombospondin (TSP) type I motif, the expression of which is associated with inflammatory processes. In the present study, we have characterized the exon/intron organization of the mouse ADAMTS-1 gene. The ADAMTS-1 gene is composed of nine exons, all of which are present within the 9.2-kb genomic region. Among the nine exons, exons 1, 5, and 6 encode a proprotein domain, a disintegrin-like domain, and a TSP type I motif, respectively, of the ADAMTS-1 protein, suggesting that there is a correlation between exon/intron organization and functional domains. In addition, the exon/ intron organization of the ADAMTS-1 gene is very different from that of the metalloproteinase-like/disintegrin-like/ cysteine-rich protein gene (MDC) (ADAM11), suggesting that the genomic structure of ADAM family genes is not necessarily conserved. Furthermore, fluorescence in situ hybridization revealed that the ADAMTS-1 gene is located in region C3-C5 of chromosome 16, to which none of the previously identified ADAM genes have been mapped.
