cDNAs coding for human proteins having transmembrane domains

1. Technical Field The invention provides cDNAs coding for human proteins having transmembrane domains and eucaryotic cells expressing said cDNAs. The cDNAs of the invention can be utilized as probes for the gene diagnosis and gene sources for the gene therapy. Furthermore, the cDNAs can be utilized for large-scale expression of said proteins. Cells, wherein these membrane protein genes are introduced and membrane proteins are expressed in large amounts, can be utilized for detection of the corresponding ligands, screening of novel low-molecular pharmaceuticals, and so on.
