IP₃-mediated Ca²⁺ release regulates atrial Ca²⁺ transients and pacemaker function by stimulation of adenylyl cyclases.

Am J Physiol Heart Circ Physiol, 2021
Inositol trisphosphate (IP3) is a Ca2+-mobilizing second messenger shown to modulate atrial muscle contraction, and is thought to contribute to atrial fibrillation.

Assessing potency and binding kinetics of soluble adenylyl cyclase (sAC) inhibitors to maximize therapeutic potential

Frontiers in Physiology, 2022
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 ...

Malignant progression of liver cancer progenitors requires lysine acetyltransferase 7–acetylated and cytoplasm‐translocated G protein GαS

Hepatology, EarlyView., 2022
KAT7‐acetylated and cytoplasm‐translocated G‐protein GαS enhances IL‐6 effect and drives HCC progenitor cell progression. Abstract Background and Aims Hepatocarcinogenesis goes through HCC progenitor cells (HcPCs) to fully established HCC, and the mechanisms driving the development of HcPCs are still largely unknown.

Structural basis of adenylyl cyclase 9 activation

Nature Communications, 2022
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 ...

The Receptor-Bound Guanylyl Cyclase DAF-11 Is the Mediator of Hydrogen Peroxide-Induced cGMP Increase in Caenorhabditis elegans [corrected].. [PDF]

PLoS ONE, 2013
Adenosine 3', 5'-cyclic monophosphate (cAMP) and guanosine 3', 5'-cyclic monophosphate (cGMP) are well-studied second messengers that transmit extracellular signals into mammalian cells, with conserved functions in various other species such as ...

AKAP79 Orchestrates a Cyclic AMP Signalosome Adjacent to Orai1 Ca2+ Channels

Function, 2021
To ensure specificity of response, eukaryotic cells often restrict signalling molecules to sub-cellular regions. The Ca2+ nanodomain is a spatially confined signal that arises near open Ca2+ channels.

cAMP Signaling Compartmentation: Adenylyl Cyclases as Anchors of Dynamic Signaling Complexes. [PDF]

Mol Pharmacol, 2018
It is widely accepted that cAMP signaling is compartmentalized within cells. However, our knowledge of how receptors, cAMP signaling enzymes, effectors and other key proteins form specific signaling complexes to regulate specific cell responses is ...

A molecular dynamics study of adenylyl cyclase: The impact of ATP and G-protein binding. [PDF]

PLoS ONE, 2018
Adenylyl cyclases (ACs) catalyze the biosynthesis of cyclic adenosine monophosphate (cAMP) from adenosine triphosphate (ATP) and play an important role in many signal transduction pathways.
