Unwinding of a cholesteric liquid crystal and bidirectional surface anchoring [PDF]

, 2013
We examine the influence of bidirectional anchoring on the unwinding of a planar cholesteric liquid crystal induced by the application of a magnetic field. We consider a liquid crystal layer confined between two plates with the helical axis perpendicular

A-Kinase Anchoring Protein Targeting of Protein Kinase A and Regulation of HERG Channels [PDF]

Journal of Membrane Biology, 2008
Adrenergic stimulation of the heart initiates a signaling cascade in cardiac myocytes that increases the concentration of cAMP. Although cAMP elevation may occur over a large area of a target-organ cell, its effects are often more restricted due to local concentration of its main effector, protein kinase A (PKA), through A-kinase anchoring proteins ...

Subcellular location of PKA controls striatal plasticity: stochastic simulations in spiny dendrites. [PDF]

PLoS Computational Biology, 2012
Dopamine release in the striatum has been implicated in various forms of reward dependent learning. Dopamine leads to production of cAMP and activation of protein kinase A (PKA), which are involved in striatal synaptic plasticity and learning.

Regulation of CaV1.2 Current: Interaction With Intracellular Molecules

Journal of Pharmacological Sciences, 2007
CaV1.2 (α1c) is a pore-forming subunit of the voltage-dependent L-type calcium channel and is expressed in many tissues. The β and α2/δ subunits are auxiliary subunits that affect the kinetics and the expression of CaV1.2.

Bub1 is a fission yeast kinetochore scaffold protein, and is sufficient to recruit other spindle checkpoint proteins to ectopic sites on chromosomes [PDF]

, 2007
The spindle checkpoint delays anaphase onset until all chromosomes have attached in a bi-polar manner to the mitotic spindle. Mad and Bub proteins are recruited to unattached kinetochores, and generate diffusible anaphase inhibitors.

Glucose deprivation affects the expression of genes encoding cAMP-activated protein kinase and related proteins in U87 glioma cells in ERN1 dependent manner

Endocrine Regulations, 2020
Objective. The aim of this investigation was to study the expression of genes encoding cAMP-activated protein kinase catalytic and regulatory A subunits (PRKACA and PRKAR1A) and related proteins such as cAMP-dependent protein kinase inhibitors A and G ...

Identification of Sperm-specific Proteins That Interact with A-kinase Anchoring Proteins in a Manner Similar to the Type II Regulatory Subunit of PKA*

Journal of Biological Chemistry, 2001
The cAMP-dependent protein kinase (PKA) is targeted to specific subcellular compartments through its interaction with A-kinase anchoringproteins (AKAPs). AKAPs contain an amphipathic helix domain that binds to the type II regulatory subunit of PKA (RII).

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

FEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

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

Journal 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

14-3-3 Proteins Interact with a Hybrid Prenyl-Phosphorylation Motif to Inhibit G Proteins [PDF]

, 2013
Signaling through G proteins normally involves conformational switching between GTP- and GDP-bound states. Several Rho GTPases are also regulated by RhoGDI binding and sequestering in the cytosol.
