TLDR
The regulation of many of the ACs by the ubiquitous second messenger Ca(2+) provides an overarching mechanism for integrating the activities of these two major signaling systems, and cAMP will exhibit distinct kinetics in discrete cellular domains.
Abstract
The adenylyl cyclases are variously regulated by G protein subunits, a number of serine/threonine and tyrosine protein kinases, and Ca2+. In some physiological situations, this regulation can be re...

A Coupled SYSTEM of Intracellular Ca2+ Clocks and Surface Membrane Voltage Clocks Controls the Timekeeping Mechanism of the Heart’s Pacemaker

TL;DR: Evidence is examined that forms the basis of this coupled-clock system concept in cardiac SANCs, where G protein-coupled receptors signaling creates pacemaker flexibility, ie, effects changes in the rhythmic action potential firing rate, by impacting on these very same factors that regulate robust basal coupled- clock system function.

Underpinning compartmentalised cAMP signalling through targeted cAMP breakdown

TL;DR: Genes for these important regulatory enzymes are linked to schizophrenia, stroke and asthma, thus indicating the therapeutic potential that selective inhibitors could have as anti-inflammatory, anti-depressant and cognitive enhancer agents.

Cyclic GMP phosphodiesterase-5: target of sildenafil.

TL;DR: The characteristics of PDE5, its relationship to other PDEs, its role in cGMP signaling, and its involvement in the efficacious action of sildenafil on corpus cavernosum and vascular smooth muscle resulting in penile erection are the subjects of this review.

Regulation of NMDA Receptors by an Associated Phosphatase-Kinase Signaling Complex

TL;DR: Yotiao is a scaffold protein that physically attaches PP1 and PKA to NMDA receptors to regulate channel activity and targeting of these enzymes near the substrate is proposed to enhance phosphorylation-dependent modulation.
