A-kinase-interacting protein localizes protein kinase A in the nucleus [PDF]
The genetic variability and covalent modifications associated with the amino terminus of the protein kinase A (PKA) catalytic (C) subunit suggest that it may contribute to protein–protein interactions and/or localization. By using a yeast two-hybrid screen, we identified a PKA-interacting protein (AKIP1) that binds to the amino terminus (residues 1–39)

The Kinase Specificity of Protein Kinase Inhibitor Peptide
G-protein-coupled-receptor (GPCR) signaling is exquisitely controlled to achieve spatial and temporal specificity. The endogenous protein kinase inhibitor peptide (PKI) confines the spatial and temporal spread of the activity of protein kinase A (PKA ...

Role of adenosine triphosphate and protein kinase A in the force-frequency relationship in isolated rat cardiomyocytes [PDF]
The physiological heart rate of rodents is around 4-6 Hz, although a stimulus frequency of 1 Hz is generally used in isolated cardiomyocytes to study changes in the contraction-relaxation cycle in cardiac muscle physiology and pathophysiology.

A-kinase-anchoring proteins [PDF]
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-

Cardiac cAMP-PKA Signaling Compartmentalization in Myocardial Infarction
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.

Beta-adrenergic agonist protects retinal pigment epithelium against hydroxycholoroquine toxicity via cAMP-PKA signal pathway [PDF]
AIM: To test our hypothesis that activation of protein kinase A (PKA) signal pathway by β-adrenergic agonist plays an important role in the protecting of cultured retinal pigment epithelial (RPE) cells against the hydroxychloroquine (HCQ) toxicity ...

Protein Kinase A Anchoring [PDF]
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.

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