Mapping of adenylyl cyclase genes type I,II, III,IV, V,and VI in mouse

The adenylyl cyclases (AC) act as second messengers in regulatory processes in the central nervous system. They might be involved in the pathophysiology of diseases, but their biological function is unknown, except for AC type I, which has been implicated in learning and memory. We previously mapped the gene encoding AC I to human Chromosome (Chr) 7p12. In this study we report the mapping of the adenylyl cyclase genes type I–VI to mouse chromosomes by fluorescence in situ hybridization (FISH): Adcy1 to Chr 11A2, Adcy2 to 13C1, Adcy3 to 12A-B, Adcy4 to 14D3, Adcy5 to 16B5, and Adcy6 to 15F. We also confirmed previously reported mapping results of the corresponding human loci ADCY2, ADCY3, ADCY5, and ADCY6 to human chromosomes and, in addition, determined the chromosomal location of ADCY4 to human Chr 14q11.2. The mapping data confirm known areas of conservation between mouse and human chromosomes.
