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...

Principles of c-di-GMP signalling in bacteria.

TL;DR: This Review focuses on emerging principles of c-di-GMP signalling using selected systems in different bacteria as examples.

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.

Caveolae as Organizers of Pharmacologically Relevant Signal Transduction Molecules

TL;DR: The role of Caveolae/caveolin in cardiac and pulmonary pathophysiology, pharmacologic implications of caveolar localization of signaling molecules, and the possibility that caveolae might serve as a therapeutic target are reviewed.

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.

Physiological roles for G protein-regulated adenylyl cyclase isoforms: insights from knockout and overexpression studies.

TL;DR: The latest on AC knockout and overexpression studies are explored to better understand the roles of G protein regulation of ACs in the brain, olfactory bulb, and heart.

Cholesterol Depletion Inhibits Epidermal Growth Factor Receptor Transactivation by Angiotensin II in Vascular Smooth Muscle Cells ROLE OF CHOLESTEROL-RICH MICRODOMAINS AND FOCAL ADHESIONS IN ANGIOTENSIN II SIGNALING

TL;DR: It is shown that cholesterol depletion by β-cyclodextrin disrupts caveolae structure and concomitantly inhibits tyrosine phosphorylation of the EGF-R and subsequent activation of protein kinase B (PKB)/Akt induced by angiotensin II, and cholesterol-rich microdomains as well as focal adhesions are important signal-organizing compartments required for the spatial and temporal organization of angiotsin II signaling in VSMCs.

Regulation and function of the cyclic nucleotide phosphodiesterase (PDE3) gene family.

TL;DR: This chapter discusses some general information about cyclic nucleotide phosphodiesterases (PDEs), and discusses the PDE3 gene family, emphasizing the molecular biology, structure/function relationships, and cellular regulation and functional roles of Pde3s, as well as physiological/pharmacological actions, therapeutic applications, and potential benefits of PDE2 inhibitors.

Endogenous TRPC1, TRPC3, and TRPC7 Proteins Combine to Form Native Store-operated Channels in HEK-293 Cells

TL;DR: Endogenously expressed canonical transient receptor potential (TRPC) homologs participate in forming heteromeric store-operated channels, whereas TRPC1, TRPC3, and TRPC7 can also participate in form heteromersic receptor- operated channels.

Functional stoichiometry and local enrichment of calmodulin interacting with Ca2+ channels

TL;DR: This estimate indicates marked enrichment of local CaM, as if a “school” of nearby CaMs were poised to enhance the transduction of localCa2+ entry into diverse signaling pathways.
