The Role of G Protein-coupled Receptor Kinases in Cancer [PDF]

International Journal of Biological Sciences, 2018
G protein-coupled receptors (GPCRs) are the largest family of plasma membrane receptors. Emerging evidence demonstrates that signaling through GPCRs affects numerous aspects of cancer biology such as vascular remolding, invasion, and migration. Therefore, development of GPCR-targeted drugs could provide a new therapeutic strategy to treating a variety ...

G protein—coupled receptor kinase (GRK)

Folia Pharmacologica Japonica, 2010
Gタンパク質共役受容体キナーゼ（G Protein-coupled Receptor Kinase: GRK）の分子機能，分子構造，生理的役割を解説する．GRKは，Gタンパク質共役受容体（G Protein-Coupled Receptor: GPCR）をリン酸化するセリン・トレオニンキナーゼである．基本的な作用機構は，(1)アゴニスト結合した受容体（GPCR）がGRKを活性化，(2)活性化されたGRKが受容体をリン酸化，(3)リン酸化された受容体にアレスチン（arrestin）が結合，(4)その結果受容体の脱感受性（desensitization）が起こる，というものである．脱感受性は，受容体とGタンパク質との相互作用が損なわれる脱共役（uncoupling），受容体の細胞内への移行 ...

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Regulation of G Protein-coupled Receptor Kinases by Caveolin [PDF]

Journal of Biological Chemistry, 1999
G protein-coupled receptor kinases (GRKs) have been principally characterized by their ability to phosphorylate and desensitize G protein-coupled receptors. However, recent studies suggest that GRKs may have more diverse protein/protein interactions in cells.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Caveolae-Independent Activation of Protein Kinase A in Rat Neonatal Myocytes

Journal of Pharmacological Sciences, 2005
Cardiomyocytes express both β1- and β2-adrenergic receptors, and these receptors play a differential role in chronotropic and inotropic effects of the heart. Caveolae are known as an important regulator of G-protein-coupled receptor signaling.

Endothelial APC/PAR1 distinctly regulates cytokine-induced pro-inflammatory VCAM-1 expression

Frontiers in Molecular Biosciences, 2023
Introduction: Dysfunction of the endothelium impairs its’ protective role and promotes inflammation and progression of vascular diseases. Activated Protein C (APC) elicits endothelial cytoprotective responses including barrier stabilization, anti ...

G Protein-Coupled Receptor Kinases Take Central Stage

Cells, 2022
The relevance of the family of G protein-coupled receptor kinases (GRKs) is based on its key participation in the regulation and intracellular dynamics of the largest family of membrane receptors, namely G protein-coupled receptors (GPCRs) [...]

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane

FEBS Letters, EarlyView.
Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.
