Molecular cloning of the human histamine H1 receptor gene.
The human histamine H1 receptor gene, an intron-lacking gene, was isolated with bovine H1 receptor cDNA [Yamashita, M., Fukui, H., Sugama, K., Horio, Y., Ito, S., Mizuguchi, H., and Wada, H. (1991) Proc. Natl. Acad. Sci. USA 88, 11515-11519] used as a probe. The receptor protein deduced from the nucleotide sequence of this gene was composed of 487 amino acid residues with a calculated Mr of 55,781 and possessed characteristic properties of GTP binding protein-coupled receptors. At the 5' flanking region of the human H1 receptor gene, we located potential TATA box and CACCC sequences, AP1 binding site-like sequences, glucocorticoid responsive element-like sequences, and other binding sequences for inducers. Northern blot analysis showed that H1 receptor mRNAs visualized as two bands with 3.0-kilobase and 3.5-kilobase nucleotides were expressed in peripheral tissues such as placenta, lung, skeletal muscle, and kidney and that only one species with 3.5-kilobase nucleotides was present in the brain. H1 receptor mRNA was most abundant in the placenta. The human H1 receptor gene was mapped to the chromosome 3p25 by the fluorescence in situ hybridization method.
