Cardiac cAMP-PKA Signaling Compartmentalization in Myocardial Infarction

open access: yesCells, 2021
Under physiological conditions, cAMP signaling plays a key role in the regulation of cardiac function. Activation of this intracellular signaling pathway mirrors cardiomyocyte adaptation to various extracellular stimuli.

Subcellular Propagation of Cardiomyocyte β-Adrenergic Activation of Calcium Uptake Involves Internal β-Receptors and AKAP7

open access: yesFunction, 2022
β-adrenergic receptor (β-AR) signaling in cardiac myocytes is central to cardiac function, but spatiotemporal activation within myocytes is unresolved. In rabbit ventricular myocytes, β-AR agonists or high extracellular [Ca] were applied locally at one ...

A-Kinase Anchoring Proteins in Cardiac Myocytes and Their Roles in Regulating Calcium Cycling

open access: yesCells, 2023
The rate of calcium cycling and calcium transient amplitude are critical determinants for the efficient contraction and relaxation of the heart. Calcium-handling proteins in the cardiac myocyte are altered in heart failure, and restoring the proper ...

A-kinase-anchoring proteins [PDF]

open access: yesJournal of Cell Science, 2004
Highly organized molecular complexes determine the precise location and timing of the signal transduction events that occur downstream of cell surface receptor activation ([Pawson and Nash, 2003][1]). One set of scaffolding molecules that organize such complexes is a family of proteins known as A-

Protein Kinase A Anchoring [PDF]

open access: yesJournal of Biological Chemistry, 1997
Specificity is perhaps the most enigmatic property of hormonemediated signaling pathways, especially when one considers that more than 30 hormones employ the ubiquitous second messengers, Ca, phospholipid, or cAMP, to relay messages from the cell membrane to intracellular effectors.

AKAP79 enables calcineurin to directly suppress protein kinase A activity

open access: yeseLife, 2021
Interplay between the second messengers cAMP and Ca2+ is a hallmark of dynamic cellular processes. A common motif is the opposition of the Ca2+-sensitive phosphatase calcineurin and the major cAMP receptor, protein kinase A (PKA).

A-Kinase Anchoring Proteins [PDF]

open access: yesCirculation, 2010
The heart is a sophisticated organ that continuously pumps blood to ensure that oxygen and nutrients reach the brain, other organs, and peripheral tissue. The right side of the heart pumps blood to the lungs, where oxygen is taken up and carbon dioxide is removed.
