adenylyl cyclase is a membrane-bound enzyme that catalyzes the conversion of atp to camp. the inhibition of adenylyl cyclase was carried out by measuring the ability of the macrophage chemotactic protein-1 to inhibit the torskolin-induced enzyme activity. adenylyl cyclase activity in the presenc of macrophage chemotactic protein-1 was decreased compared to that in controls [2.11+/-0.15 (mean +/...

Adenylyl cyclase, E.C. 4.6.1.1, converts ATP to cyclic AMP and pyrophosphate. Mammalian membrane-delimited adenylyl cyclases (nomenclature as approved by the NC-IUPHAR Subcommittee on [11]) are typically made up of two clusters six TM domains separating intracellular, overlapping catalytic that target for nonselective activators Gαs (the stimulatory G protein α subunit) forskolin (except AC9, [...

phosphodiesterases  (pde)  hydrolyse intracellular camp  and  cgmp  to  inactive  5’ monophosphates. decreased level of camp is involved in the pathogenesis of asthma. we and others have shown that phosphodiesterases were upregulated in the lung of allergic rats, and bacilli calmette-guérin (bcg) induced the production of camp in vitro. however, it is unclear how bcg’s effect asthma and whether...

We cloned the adenylyl cyclase gene from the fission yeast Schizosaccharomyces pombe using low-stringency hybridization to the Saccharomyces cerevisiae adenylyl cyclase gene. The Sc. pombe gene encodes a 1692-amino acid-residue protein. The identity of this gene was confirmed by studies of its expression in Sa. cerevisiae. Expression of the carboxyl-terminal region of the Sc. pombe adenylyl cyc...

The aim of the present study was to identify which adenylyl cyclase isoforms were expressed in the human adrenal gland and to determine which isoform(s) may be coupled to ACTH action. Our results indicate that, in both glomerulosa and fasciculata zones, adenylyl cyclase 1 was detected in cells at the membrane level, adenylyl cyclases 3 and 2 in both the cytoplasm and the plasma membrane, wherea...

Long-term opioid agonist treatment results in adenylyl cyclase superactivation. A recent "RAVE" theory implicates a direct correlation between the ability of agonist to induce receptor internalization and the magnitude of adenylyl cyclase superactivation. We decided to test such a theory by examining the adenylyl cyclase superactivation after long-term activation of mu-opioid receptor (MOR) in ...
