OR15-5 Human Sex Determination at the Edge of Ambiguity: Impaired SRY Phosphorylation Attenuates Expression of the Male Program [PDF]

, 2019
A paradox is posed by metazoan gene-regulatory networks (GRNs) that are robust yet evolvable. Insight may be obtained through studies of bistable genetic circuits mediating developmental decisions. A model in organogenesis is provided by the sex-specific

Leucine-rich repeat kinase 2 controls protein kinase A activation state through phosphodiesterase 4

Journal of Neuroinflammation, 2018
Background Evidence indicates a cross-regulation between two kinases, leucine-rich repeat kinase 2 (LRRK2) and protein kinase A (PKA). In neurons, LRRK2 negatively regulates PKA activity in spiny projecting neurons during synaptogenesis and in response ...

Activation of PKA via asymmetric allosteric coupling of structurally conserved cyclic nucleotide binding domains

Nature Communications, 2019
Protein kinase A (PKA) is a cyclic nucleotide dependent protein kinase. Here the authors use single molecule optical tweezers and steered molecular dynamic simulations to follow in real time and quantitatively characterize the signals transduced by cAMP ...

Functional mapping of protein kinase A reveals its importance in adult Schistosoma mansoni motor activity.

PLoS Neglected Tropical Diseases, 2013
Cyclic AMP (cAMP)-dependent protein kinase/protein kinase A (PKA) is the major transducer of cAMP signalling in eukaryotic cells. Here, using laser scanning confocal microscopy and 'smart' anti-phospho PKA antibodies that exclusively detect activated PKA,

Intracellular mechanisms underlying the nicotinic enhancement of LTP in the rat dentate gyrus [PDF]

, 2008
We have previously shown that activation of nicotinic acetylcholine receptors (nAChRs) enhanced long-term potentiation (LTP) in the rat dentate gyrus in vitro via activation of α7 nAChR. In the present studies, mechanisms underlying the acute and chronic

New Aspects for the Treatment of Cardiac Diseases Based on the Diversity of Functional Controls on Cardiac Muscles: Mitochondrial Ion Channels and Cardioprotection

Journal of Pharmacological Sciences, 2009
Mitochondrial ATP-sensitive K+ (mitoKATP) and Ca2+-activated K+ (mitoKCa) channels exist in cardiac myocytes, and they play key roles in cardioprotection.

Multi-state recognition pathway of the intrinsically disordered protein kinase inhibitor by protein kinase A

eLife, 2020
In the nucleus, the spatiotemporal regulation of the catalytic subunit of cAMP-dependent protein kinase A (PKA-C) is orchestrated by an intrinsically disordered protein kinase inhibitor, PKI, which recruits the CRM1/RanGTP nuclear exporting complex.

The centrosomal deubiquitylase USP21 regulates Gli1 transcriptional activity and stability [PDF]

, 2016
USP21 is a centrosome-associated deubiquitylase (DUB) that has been implicated in the formation of primary cilia - crucial organelles for the regulation of the Hedgehog (Hh) signaling pathway in vertebrates. Here, we identify KCTD6 - a cullin-3 E3-ligase

Protein kinase a distribution differentiates human glioblastoma from brain tissue [PDF]

, 2017
Brain tumor glioblastoma has no clear molecular signature and there is no effective therapy. In rodents, the intracellular distribution of the cyclic AMP (cAMP)-dependent protein kinase (Protein kinase A, PKA) R2Alpha subunit was previously shown to ...

Comprehensive Analysis of Aspergillus nidulans PKA Phosphorylome Identifies a Novel Mode of CreA Regulation

mBio, 2019
In filamentous fungi, an important kinase responsible for adaptation to changes in available nutrients is cyclic AMP (cAMP)-dependent protein kinase (protein kinase A [PKA]).
