Structure of the murine CD156 gene, characterization of its promoter, and chromosomal location.
The murine cell surface antigen mCD156 is a glycoprotein that is expressed in monocytic cell lines and consists of a metalloprotease domain, a disintegrin domain, a cysteine-rich domain, and an epidermal growth factor-like domain in the extracellular region. The mCD156 gene is composed of 24 exons and 23 introns and spans approximately 14 kilobases. The first exon encodes most of the signal peptide sequence, and the transmembrane region is encoded by a single exon (19). In contrast, the other regions are composed of multiple exons. Of these, exons 7-12 and 12-15 encode a metalloprotease domain and a disintegrin domain, respectively. Sequence analysis of the 5'-flanking DNA revealed many potential regulatory motifs. Chloramphenicol acetyltransferase analysis demonstrated that nucleotides at positions -183, -334, and -623 contained cis-acting enhancing elements in a mouse monocytic cell line, aHINS-B3. Nucleotides at positions -183 and -390 contained elements responsible for lipopolysaccharide (LPS) inducibility, although several other 5'-flanking regions were also involved in LPS responsiveness. Regions -202, -507, and -659 play a role in interferon-gamma inducibility. Some of the potential regulatory motifs and other unknown cis elements may be involved in the constitutive expression, and LPS and interferon-gamma inducibilities. The mCD156 gene was mapped to chromosome 7, region F3-F4.
