Structural basis of adenylyl cyclase 9 activation
Adenylyl cyclases (ACs) generate the second messenger cAMP and play an important role in cellular signaling. Here, the authors use cryo-EM to trace the conformational changes resulting from binding to partial and full activators to one of these enzymes ...

In mammalian cells, 10 different adenylyl cyclases produce the ubiquitous second messenger, cyclic adenosine monophosphate (cAMP). Amongst these cAMP-generating enzymes, bicarbonate (HCO3−)-regulated soluble adenylyl cyclase (sAC; ADCY10) is uniquely ...

Modulation of sensory information processing by a neuroglobin in C. elegans [PDF]
Sensory receptor neurons match their dynamic range to ecologically relevant stimulus intensities. How this tuning is achieved is poorly understood in most receptors. We show that in the C. elegans URX O2 sensing neurons two putative molecular O2 sensors, a neuroglobin and O2-binding soluble guanylate cyclases, work antagonistically to sculpt a slowly ...

Bicarbonate Stimulated Adenylyl Cyclases [PDF]
AbstractBicarbonate ion is fundamental to the biology of all living organisms. HCO3‐ is vital to such diverse physiological processes as carbon fixation, cellular homeostasis, sperm maturation, and nucleotide synthesis. A defined subset of adenylyl cyclases identified in eukaryotes and prokaryotes are directly activated by HCO3‐.

CO2/HCO3−- and Calcium-regulated Soluble Adenylyl Cyclase as a Physiological ATP Sensor*
Background: The affinity of soluble adenylyl cyclase (sAC) for its substrate ATP suggested that it might be sensitive to fluctuations in ATP. Results: In sAC-overexpressing and glucose-responsive cells, sAC-generated cAMP reflects intracellular ATP ...

Adenylyl cyclase VI mediates vasopressin-stimulated ENaC activity.
Vasopressin modulates sodium reabsorption in the collecting duct through adenylyl cyclase-stimulated cyclic AMP, which exists as multiple isoforms; the specific isoform involved in vasopressin-stimulated sodium transport is unknown.

Background: Soluble adenylyl cyclase (sAC) may be an alternative intracellular localized source of cAMP controlling proliferation. Results: sAC is overexpressed in prostate carcinoma, and inhibition of sAC leads to cell cycle arrest.

New Perspectives on Plant Adenylyl Cyclases [PDF]
It is increasingly clear that plant genomes encode numerous complex multidomain proteins that harbor functional adenylyl cyclase (AC) centers. These AC containing proteins have well-documented roles in development and responses to the environment. However, it is only for a few of these proteins that we are beginning to understand the intramolecular ...
