Olfactory adenylyl cyclase

Adenylyl cyclase-dependent axonal targeting in the olfactory system.

The vertebrate olfactory bulb is a remarkably organized neuronal structure, in which hundreds of functionally different sensory inputs are organized into a highly stereotyped topographical map. How this wiring is achieved is not yet understood. Here, we show that the olfactory bulb topographical map is modified in adenylyl cyclase 3 (adenylate cyclase 3)-deficient mice. In these mutants, axonal...

Adenylyl Cyclase in Yeast

The adenylyl cyclase system of the yeast Saccharomyces cerevisiae contains the CYRl polypeptide, responsible for catalyzing formation of cAMP from ATP, and two RAS polypeptides, responsible for stimulation of cAMP synthesis by guanine nucleotides. We have determined hydrodynamic properties of yeast adenylyl cyclase in taurocholate extracts of wild type and RASdeficient membranes. In taurocholat...

Bicarbonate-regulated soluble adenylyl cyclase.

Soluble adenylyl cyclase (sAC) represents a novel form of mammalian adenylyl cyclase structurally, molecularly, and biochemically distinct from the G protein-regulated, transmembrane adenylyl cyclases (tmACs). sAC possesses no transmembrane domains and is insensitive to classic modulators of tmACs, such as heterotrimeric G proteins and P site ligands. Thus, sAC defines an independently regulate...

Gene Expression Profiles of Main Olfactory Epithelium in Adenylyl Cyclase 3 Knockout Mice

Adenylyl Cyclase 3 (AC3) plays an important role in the olfactory sensation-signaling pathway in mice. AC3 deficiency leads to defects in olfaction. However, it is still unknown whether AC3 deficiency affects gene expression or olfactory signal transduction pathways within the main olfactory epithelium (MOE). In this study, gene microarrays were used to screen differentially expressed genes in ...
