Endothelial PKA activity regulates angiogenesis by limiting autophagy through phosphorylation of ATG16L1

open access: yeseLife, 2019
The cAMP-dependent protein kinase A (PKA) regulates various cellular functions in health and disease. In endothelial cells PKA activity promotes vessel maturation and limits tip cell formation.

Modulation of HERG K+ Channels by Chronic Exposure to Activators and Inhibitors of PKA and PKC: Actions Independent of PKA and PKC Phosphorylation

open access: yesCellular Physiology and Biochemistry, 2013
Background: Human ether-a-go-go-related gene (HERG) channel is the major molecular component of the native rapid delayed rectifier K+ current (IKr) that is a crucial determinant of cardiac repolarization.

Dephosphorylation specificities of protein phosphatase for cardiac troponin I, troponin T, and sites within troponin T

open access: yesInternational Journal of Biological Sciences, 2006
Protein dephosphorylation by protein phosphatase 1 (PP1), acting in concert with protein kinase C (PKC) and protein kinase A (PKA), is a pivotal regulatory mechanism of protein phosphorylation.

GABAC-Receptor Stimulation Activates cAMP-Dependent Protein Kinase via A-Kinase Anchoring Protein 220

open access: yesJournal of Pharmacological Sciences, 2008
In our previous study, anti-apoptotic effects of GABAC-receptor stimulation was suppressed by inhibitors of cAMP-dependent protein kinase (PKA), implying GABACreceptor–mediated PKA activation. The present study showed that GABAC-receptor stimulation with

Polymorphisms/Mutations in A-Kinase Anchoring Proteins (AKAPs): Role in the Cardiovascular System

open access: yesJournal of Cardiovascular Development and Disease, 2018
A-kinase anchoring proteins (AKAPs) belong to a family of scaffolding proteins that bind to protein kinase A (PKA) by definition and a variety of crucial proteins, including kinases, phosphatases, and phosphodiesterases.

Fragile X Mental Retardation Protein positively regulates PKA anchor Rugose and PKA activity to control actin assembly in learning/memory circuitry

open access: yesNeurobiology of Disease, 2019
Recent work shows Fragile X Mental Retardation Protein (FMRP) drives the translation of very large proteins (>2000 aa) mediating neurodevelopment.

Regulation of IKs Potassium Current by Isoproterenol in Adult Cardiomyocytes Requires Type 9 Adenylyl Cyclase

open access: yesCells, 2019
The subunits KCNQ1 and KCNE1 generate the slowly activating, delayed rectifier potassium current, IKs, that responds to sympathetic stimulation and is critical for human cardiac repolarization.

Bora bridges Aurora-A activation and substrate recognition of PLK1

open access: yesEMBO Reports
The activation of PLK1 in late G2 is critical for mitotic entry, requiring its phosphorylation by Aurora-A, facilitated by the intrinsically disordered protein Bora. The structural basis of this mechanism has remained unresolved.

Protein Kinase A Regulates Platelet Phosphodiesterase 3A through an A-Kinase Anchoring Protein Dependent Manner

open access: yesCells
Platelet activation is critical for haemostasis, but if unregulated can lead to pathological thrombosis. Endogenous platelet inhibitory mechanisms are mediated by prostacyclin (PGI2)-stimulated cAMP signalling, which is regulated by phosphodiesterase 3A (

Autophagosomes anchor an AKAP11-dependent regulatory checkpoint that shapes neuronal PKA signaling

open access: yesThe EMBO Journal
Protein Kinase A (PKA) is regulated spatially and temporally via scaffolding of its catalytic (Cα) and regulatory (RI/RII) subunits by the A-kinase-anchoring proteins (AKAP). By binding to an AKAP11 scaffold, PKA engages in poorly understood interactions
