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 ...

GRKs as Modulators of Neurotransmitter Receptors

Cells, 2020
Many receptors for neurotransmitters, such as dopamine, norepinephrine, acetylcholine, and neuropeptides, belong to the superfamily of G protein-coupled receptors (GPCRs). A general model posits that GPCRs undergo two-step homologous desensitization: the

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 ...

ABL kinase‐dependent phosphorylation of SH proteins promotes their direct interaction with CRK family SH2 domains

FEBS Letters, EarlyView.
CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.

Nutrient/TOR signaling controls adipose mitochondrial transcription factor A (TFAM) to regulate organismal growth in Drosophila

FEBS Letters, EarlyView.
Animals must match their growth rate to available nutrients. We show that in Drosophila larvae, the nutrient‐sensing TOR kinase controls growth by regulating levels of TFAM, a key regulator of mitochondrial function, in the adipose tissue. When nutrients are abundant, high TOR activity suppresses TFAM, lowering mitochondrial bioenergetic activity and ...

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.

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) [...]

Liver organoids: modelling complexity in homeostasis and disease

FEBS Letters, EarlyView.
Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses

Autophagy and mitophagy in pancreatic β‐cell homeostasis and their involvement in diabetes pathophysiology

FEBS Letters, EarlyView.
This review focuses on the role of autophagy and mitophagy in maintaining pancreatic β‐cell function and homeostasis. We discuss how genetic defects affecting these pathways contribute to the development of type 1, type 2, monogenic, and gestational diabetes. We further explore their potential as therapeutic targets. Created in BioRender.
